AB  - Background The majority of CAKUT-associated CNVs overlap at least one miRNA gene, thus affecting the cellular levels of the corresponding miRNA. We aimed to investigate the potency of restitution of CNV-affected miRNA levels to remediate the dysregulated expression of target genes involved in kidney physiology and development in vitro.  Methods Heterozygous MIR484 knockout HEK293 and homozygous MIR185 knockout HEK293 cell lines were used as models depicting the deletion of the frequently affected miRNA genes by CAKUT-associated CNVs. After treatment with the corresponding miRNA mimics, the levels of the target genes have been compared to the non-targeting control treatment. For both investigated miRNAs, MDM2 and PKD1 were evaluated as common targets, while additional 3 genes were investigated as targets of each individual miRNA (NOTCH3, FIS1 and APAF1 as hsa-miR-484 targets and RHOA, ATF6 and CDC42 as hsa-miR-185-5p targets).  Results Restitution of the corresponding miRNA levels in both knockout cell lines has induced a change in the mRNA levels of certain candidate target genes, thus confirming the potential to alleviate the CNV effect on miRNA expression. Intriguingly, HEK293 WT treatment with investigated miRNA mimics has triggered a more pronounced effect, thus suggesting the importance of miRNA interplay in different genomic contexts.  Conclusions Dysregulation of multiple mRNA targets mediated by CNV-affected miRNAs could represent the underlying mechanism behind the unresolved CAKUT occurrence and phenotypic variability observed in CAKUT patients. Characterizing miRNAs located in CNVs and their potential to become molecular targets could eventually help in understanding and improving the management of CAKUT.

AB  - Congenital anomalies of the kidney and urinary tract (CAKUT) represent structural and functional urinary system malformations and take place as one of the most common congenital malformations with an incidence of 1:500. Ureteral obstruction-induced hydronephrosis is associated with renal fibrosis and chronic kidney diseases in the pediatric CAKUT. We aimed to construct interaction network of previously bioinformatically associated miRNAs with CAKUT differentially expressed genes in order to prioritize those associated with fibrotic process and to experimentally validate the expression of selected miRNAs in CAKUT patients compared to control group. We constructed interaction network of hsa-miR-101-3p, hsa-miR-101-5p and hsa-miR-29c-3p that showed significant association with fibrosis. The top enriched molecular pathway was extracellular matrix-receptor interaction (adjusted p = .0000263). We experimentally confirmed expression of three miRNAs (hsa-miR-29c-3p, hsa-miR-101-3p and hsa-miR-101-5p) in obstructed ureters (ureteropelvic junction obstruction and primary obstructive megaureter) and vesicoureteral reflux. The hsa-miR-29c-3p was shown to have lower expression in both patient groups compared to controls. Relative levels of hsa-miR-101-5p and hsa-miR-101-3p showed significant positive correlations in both groups of patients. Statistically significant correlation was observed between hsa-miR-101 (-3p and -5p) and hsa-miR-29c-3p only in the obstructed group. The significant downregulation of anti-fibrotic hsa-miR-29c-3p in obstructive CAKUT could explain activation of genes involved in fibrotic processes. As miRNAs are promising candidates in therapeutic approaches our results need further measurement of fibrotic markers or assessment of extent of fibrosis and functional evaluation of hsa-miR-29c.

AB  - Molecular background and biomarkers of highly heterogenous and hardly predictable disease progression among relapse-onset MS patients are of high research interest. In the current pilot study, we aimed to employ next-generation sequencing to investigate the expression of whole small non-coding microRNAs (miRNome) in two groups of MS patients with highly distinctive progression phenotype: one with fast progressing, severely disabling course vs. mild course of MS, longitudinally followed 10 years. Peripheral blood mononuclear cells (PBMC) miRNome data was obtained from mild phenotype MS (n=4 patients) and progressive phenotype MS (n=5 patients), using TakaraBio SMARTer smRNA-Seq Kit on iSeq100 (Illumina). Pre-processing of raw sequencing data, quality control and miRNA differential expression analysis was performed using sRNAtoolbox pipeline. Functional interpretation of differentially expressed miRNA target genes was done in DIANA-miRPathv3.0. Tarbase v8.0 served as a resource of miRNA:gene interactions. Achieved read depth was approximately 1 million raw reads/sample, allowing detection of up to 92 mature miRNAs after genome alignment and miRbase v22 annotation. Differential expression analysis identified the significant upregulation of hsa-miR-23c (log2FC=4.29, Padj= 0.03) in progressive phenotype. Top significantly enriched KEGG pathways in hsa-miR-23c targets suggested regulation of molecular pathways involved in autoimmunity (antigen presentation, Epstein-Barr virus infection) and cancer. In conclusion, this pilot study indicates phenotype-related differences in expression of miRNAs, molecules with high regulatory and biomarker properties. Although detected in PBMC, has-miR-23c is highly expressed in the brain and target MS relevant genes such as, HLA (A, B, C), transferrin receptor, Nrf2, recently proposed to play important role in neurodegeneration.

AB  - Rare copy number variants (CNVs) are among the most common genomic disorders underlying CAKUT. miRNAs located in rare CNVs represent well-founded functional variants for human CAKUT research. The study aimed to identify and functionally interpret miRNAs most frequently affected by rare CNVs in CAKUT and to estimate the overall burden of rare CNVs on miRNA genes in CAKUT. The additional aim of this study was to experimentally confirm the effect of a rare CNV in CAKUT on candidate miRNA’s expression and the subsequent change in mRNA levels of selected target genes. A database of CAKUT-associated rare CNV regions, created by literature mining, was used for mapping of the miRNA precursors. miRNAs and miRNA families, most frequently affected by rare CAKUT-associated CNVs, have been subjected to bioinformatic analysis. CNV burden analysis was performed to identify chromosomes with over/underrepresentation of miRNA genes in rare CNVs associated with CAKUT. A functional study was performed on HEK293 MIR484+/- KO and HEK293 WT cell lines, followed by the analysis of relative miRNA and mRNA target gene levels. 80% of CAKUT patients with underlying rare CNV had at least one miRNA gene overlapping the identified CNV. Network analysis of the most frequently affected miRNAs has revealed the dominant regulation of the two miRNAs, hsa-miR-484 and hsa-miR-185-5p. Additionally, miR-548 family members have shown substantial enrichment in rare CNVs in CAKUT. An over/underrepresentation of miRNA genes in rare CNVs associated with CAKUT was observed in multiple chromosomes, such as chr16, chr20, and chr21. A significant 0.37 fold downregulation of hsa-miR-484, followed by a notable upregulation of MDM2 and APAF1 and downregulation of NOTCH3 was detected in HEK293 MIR484+/- KO compared to HEK293 WT cell lines, supporting the study hypothesis. miRNA genes are frequently affected by rare CNVs in CAKUT patients. Understanding the potential of CNV-affected miRNAs to participate in CAKUT as genetic drivers represent a crucial implication for the development of novel therapeutic approaches.

AB  - Introduction: miR-548 family members, located on all human chromosomes except chr19 and chrY, regulate podocyte differentiation in vitro, important for kidney development. Rare copy number variants (rCNVs) are the common genetic cause of Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) and could harbour miRNAs. The aim of this study was to investigate to which extent rCNVs associated with CAKUT harbour miR-548 members.
Materials and Methods: Extensive literature review was conducted to collect data of pathogenic and likely pathogenic rCNVs in CAKUT patients. UCSC genome browser tool was employed for mapping of miR-548 members onto collected rCNV regions and gnomAD SV controls database. Bioinformatic analysis was conducted using miRPathDB2 tool.
Results: We generated CAKUT database of pathogenic CNVs in 79 chromosome regions from 191 patient and likely pathogenic CNVs in 74 regions from 87 patients. Pathogenic rCNVs of seventeen patients, located on 7 chromosomes, contained at least one miR-548 member. Likely pathogenic rCNVs of 4 patients, located on 3 chromosomes, contained one of miR-548 members. Bioinformatic analysis implied the role of mapped miRNAs in the regulation of processes associated with CAKUT. In controls, only hsa-mir-548i-3 (out of 73 precursors) was mapped on polymorphic CNVs (af>1%) and wasn’t identified in patients.
Conclusions: miR-548 members located in rCNVs should be investigated in future studies as potential genetic drivers of CAKUT development, beyond protein coding genes.

AB  - Introduction: Genetic studies of congenital anomalies of the kidney and urinary tract (CAKUT) have demonstrated variable penetrability and expressivity of the associated genetic defects. Previously, it was shown that deletions of 17q12 and 22q11.2 regions were specific for kidney anomalies (KA) while 16p11.2 and 1q21.1 loci showed extensive pleiotropy in CAKUT phenotypes. CNVs affecting miRNA gene dosage have been described to have functional influence on gene expression. We aimed to conduct comprehensive in silico analysis using publicly available databases to analyze miRNA content of CAKUT-associated CNVs in quoted chromosomal loci with regard to pleiotropy.  Methods: Extensive literature review was conducted to collect data about pathogenic rCNVs associated with CAKUT. UCSC genome browser tool was employed for mapping miRNAs onto collected rCNV regions.  Results: Analysis of CNVs in CAKUT included four studies counting more than 2500 patients. In further analysis we included 191 patients harboring pathogenic CNVs. Surprisingly, CAKUT pleiotropic regions (16p11.2, 1q21.2) did not contain any miRNA. 22q11.2 showed the densest miRNAs content (n = 21).  Conclusions: Absence of miRNAs may potentially pronounce the pleiotropy of the CAKUT genetic defects, thus leading to the variety of phenotypes. Contrary, abundancy of miRNAs in 22q11.2 might be associated with reproducible phenotype, such as KA, producing the functional effect when deleted. This assumption agrees with recent results of miRNA expression variability in 22q11.2 deletion syndrome.

AB  - Objective Cholesteatoma is a challenging chronic pathology of the middle ear for which pharmacologic therapies have not been developed yet. Cholesteatoma occurrence depends on the interplay between genetic and environmental factors while master regulators orchestrating disease progression are still unknown. Therefore, in this review, we will discuss the diagnostic and therapeutic potential of non-coding RNAs (ncRNA) as a new class of regulatory molecules. Methods We have comprehensively reviewed all articles investigating ncRNAs, specifically micro RNAs (miRNAs) and long ncRNAs (lncRNA/circRNA) in cholesteatoma tissue. Results Candidate miRNA approaches indicated that miR-21 and let-7a are the major miRNAs involved in cholesteatoma growth, migration, proliferation, bone destruction, and apoptosis. Regulatory potential for the same biological processes was also observed for miR-203a. The NF-kB/miR-802/PTEN regulatory network was in relation to observed miR-21 activity in cholesteatoma as well. High throughput approaches revealed additional ncRNAs implicated in cholesteatoma pathology. Competitive endogenous RNA (ceRNA) analysis highlighted lncRNA/circRNA that could be “endogenous sponge” for miR-21 and let-7a based on the hypothesis that RNA transcripts can communicate with and regulate each other by using shared miRNA response elements. Conclusion In this review, we summarize the discoveries and role of ncRNA in major pathways in cholesteatoma and highlight the potential of miRNA-based therapeutics in the treatment of cholesteatoma. Level of Evidence: NA.

AB  - Objectives This study aimed to experimentally validate dysregulated expression of miRNA candidates selected through updated meta-analysis of most commonly deregulated miRNAs in oral cancer and to explore their diagnostic and prognostic potential. Materials and methods Five miRNAs (miR-31-3p, miR-135b-5p, miR-18a-5p, miR-30a-5p and miR-139-5p) from updated meta-signature were selected for validation by qRT-PCR method in 35 oral cancer clinical specimens and adjacent non-cancerous tissue. Results Updated meta-analysis has identified 13 most commonly deregulated miRNAs in oral cancer. Seven miRNAs were consistently up-regulated (miR-21-5p, miR-31-3p, miR-135b-5p, miR-31-5p, miR-424-5p, miR-18a-5p and miR-21-3p), while five were down-regulated (miR-139-5p, miR-30a-3p, miR-375-3p, miR-376c-3p and miR-30a-5p). Increased expression of miR-31-3p and miR-135b-5p, and decreased expression of miR-139-5p and miR-30a-5p were confirmed in oral cancer compared to adjacent non-cancerous tissue. A three miRNAs combination (miR-31-3p, miR-139-5p and miR-30a-5p) gave the most promising diagnostic potential for discriminating oral cancer from non-cancerous tissue (AUC: 0.780 [95% CI: 0.673–0.886], p < 0.0005, sensitivity 94.3%, specificity 51.4%). High expression of miR-135b-5p, miR-18a-5p and miR-30a-5p was associated with poor survival (p = 0.003, p = 0.048, p = 0.016 respectively). Conclusion miR-31-3p, miR-139-5p and miR-30a-5p panel was confirmed as a potential diagnostic biomarker when distinguishing oral cancer from non-cancerous tissue. miR-135b-5p, miR-18a-5p and miR-30a-5p might serve as potential biomarkers of poor survival of oral cancer patients.

AB  - Oral cancer is the most prevalent type of head and neck cancer, characterized by rising incidence, high relapse occurrence and low survival. There is a high demand for the identification of novel and sensitive diagnostic and prognostic molecular biomarkers of oral cancer. MicroRNAs (miRNAs) are considered as promising candidates. Previously conducted meta-analysis on high throughput miRNA profiling in oral cancer emphasized consistent down-regulation of miR-30a-5p and miR-139-5p. We aimed to validate these findings in oral cancer clinical samples and to test the diagnostic and prognostic potential of these miRNAs. Bioinformatical prediction of investigated miRNAs target genes was executed through the intersection of multiple miRNA target prediction algorithms. Enrichment analysis of miRNA target genes was performed using miRPathDB V2.0 software on GO:BP database. RNA was isolated from oral cancer and adjacent noncancerous tissue from 30 patients by miRVana kit. cDNA was synthesized by TaqMan microRNA reverse transcription kit. TaqMan gene expression kit was used for relative quantification of miRNAs normalized to RNU6B. Relative expression was calculated by comparative Ct method. The diagnostic potential was estimated by the ROC curve analysis. Expression of miR-30a-5p and miR-139-5p was dichotomized as high or low by the median. Association with clinicopathological features and miRNAs expression was calculated by χ2 test. Bioinformatical analysis demonstrated both enrichment of miR-30a-5p and miR-139-5p targets in biological processes associated with cancer pathology and complementarity in regulation of these processes thus ensuring non-redundant regulation. Both miRNA were significantly down-regulated in oral cancer compared to non-cancerous tissue (Wilcoxon test: p=0.0004, p=0.001, respectively). According to the ROC curve analysis, both miRNAs might be used as potential tools for discrimination between cancerous and non-cancerous tissue (miR-30a-5p AUC=0.677, p=0.019; miR-139-5p AUC=0.656, p=0.038). There was a significant correlation between the expression of miR-30a-5p and miR-139-5p in cancerous tissue (Spearman rank test r=0.901, p<0.0001). None of the analyzed miRNAs was associated with stage, nodal status, tumour size and overall survival (p>0.05) which indicates that miR-30a-5p and miR-139-5p can’t be used as prognostic biomarkers of oral cancer. Our results suggest that miR-30a-5p and miR-139-5p might be used as good diagnostic biomarkers for discrimination between oral cancer and non-cancerous tissue.

There was a significant correlation between the expression of miR-30a-5p and miR-139-5p in cancerous tissue (Spearman rank test r=0.901, p<0.0001). None of the analyzed miRNAs was associated with stage, nodal status, tumour size and overall survival (p>0.05) which indicates that miR-30a-5p and miR-139-5p can’t be used as prognostic biomarkers of oral cancer. Our results suggest that miR-30a-5p and miR-139-5p might be used as good diagnostic biomarkers for discrimination between oral cancer and non-cancerous tissue.",

AB  - Foods and food products that contain polyphenols are proposed to modulate risk of cardiovascular disease. The aim of this three-arm, crossover, randomized, double-blind, placebo-controlled intervention study was to examine the impact of Aronia melanocarpa juice (AMJ), high-polyphenol (AMJ treatment, 1.17 g/100 mL polyphenols) and low-polyphenol (dAMJ treatment, 0.29 g/100 mL polyphenols) dose, on the transcriptome in peripheral blood mononuclear cells (PBMC) of 19 subjects at cardiovascular risk. Transcriptome data were obtained by microarray. Bioinformatic functional annotation analysis was performed on both the whole transcriptome datasets and the differentially expressed genes (DEGs). Expression of selected DEGs was validated by RT-qPCR. Administration of AMJ and dAMJ treatments during the two consecutive four-week treatment periods had additive effects on PBMC transcriptome profiles, with the most pronounced and specific effect noticed for AMJ in the last treatment period (TP3) of the trial. Between the high-dose and low-dose treatments in TP3, there was a multitude of overlapping DEGs and DEG-enriched biological processes and pathways, which primarily included immunomodulation and regulation of cell proliferation/death. Increased expression of TNF, IL1B, IL8, RGS1, OSM, and DUSP2 in TP3 was confirmed by RT-qPCR. The results suggest the immunomodulatory effects of prolonged habitual consumption of polyphenol-rich aronia juice in individuals at cardiovascular risk.

AB  - Objectives/Hypothesis: To establish comprehensive transcriptomic profiles of cholesteatoma perimatrix tissue and granulation tissue from chronic otitis media (COM) that did not develop cholesteatoma, which can indicate molecular pathways involved in the cholesteatoma perimatrix pathology and invasiveness. Study Design: Retrospective Case Series. Methods: Transcriptome data were obtained from cholesteatoma perimatrix tissue and COM granulation tissue by an Illumina iScan microarray. Differentially expressed genes (DEGs) were subsequently analyzed using both bioinformatical functional annotation and network analysis. Expression of candidate genes (MMP9 and LCN2) was validated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) on a larger group of samples. Results: Analysis of the transcriptome led to the identification of 169 differentially expressed genes between investigated tissues. Bioinformatic analysis suggested that most significant biological processes involving DEGs were previously described in cholesteatoma pathology. Network analysis identified ERBB2, TFAP2A, and TP63 as major hubs of the DEGs molecular network. Furthermore, it was observed that the cellular component most significantly enriched in DEGs was extracellular space containing 47 DEGs. Using qRT-PCR, it was confirmed that mRNA levels of the major extracellular hub (MMP9) are increased, whereas its interacting molecule (LCN2) mRNA levels were decreased in cholesteatoma perimatrix tissue compared to COM granulation tissue. Conclusions: The current study approach offers an overall look at molecular mechanisms that describe the cholesteatoma entity by focusing exclusively on the perimatrix processes in comparison to COM granulation tissue. The observed differences in gene expression between cholesteatoma perimatrix and COM granulation tissue could suggest novel markers potentially influenced by the perimatrix–matrix molecular interplay, which is not present in COM without cholesteatoma.

AB  - Aims: (1) to identify the most dysregulated genes in ureter tissue affected by congenital anomalies of the kidney and urinary tract (CAKUT) and to extract the biological meaning of these markers; (2) to describe the key molecular networks in CAKUT and to provide expression validation of the genes selected from these networks. Main methods: Transcriptome data was obtained from ureter samples of CAKUT patients and controls by Illumina iScan microarray. Identification of differentially expressed genes was coupled with subsequent bioinformatics analyses. Expression of candidate genes was validated by qRT-PCR. Key findings: Analysis of the transcriptome led to the identification of 78 commonly dysregulated genes in CAKUT tissue compared to controls. Integrative bioinformatic analyses of differentially expressed genes identified 7 major networks. The targets for qRT-PCR validation were selected as members of the major molecular networks in CAKUT, which had both, the significant high fold change and biological relevance for CAKUT. By qRT-PCR the substantial increase of LCN2, PROM1, SOSTDC1, and decrease of INA, RASD1 and TAC3 mRNA levels was confirmed. Significance: Since CAKUT is a leading cause of end-stage renal disease in children, the search for molecular targets for postnatal therapy is of particular interest. Data described in this study represents the gene expression profile and significant molecular networks specific to human ureter affected by CAKUT. The discovery of impaired molecular factors and processes is the step towards the uncovering of the key mechanisms that reflect CAKUT postnatally and could lead to the affected tissue deterioration and end organ damage. © 2018 Elsevier Inc.

AB  - Aim: It was the aim of the study to identify commonly deregulated miRNAs in oral cancer patients by performing a meta-analysis of previously published miRNA expression profiles in cancer and matched normal non-cancerous tissue in such patients. Material and methods: Meta-analysis included seven independent studies analyzed by a vote-counting method followed by bioinformatic enrichment analysis. Results: Amongst seven independent studies included in the meta-analysis, 20 miRNAs were found to be deregulated in oral cancer when compared with non-cancerous tissue. Eleven miRNAs were consistently up-regulated in three or more studies (miR-21-5p, miR-31-5p, miR-135b-5p, miR-31-3p, miR-93-5p, miR-34b-5p, miR-424-5p, miR-18a-5p, miR-455-3p, miR-450a-5p, miR-21-3p), and nine were down-regulated (miR-139-5p, miR-30a-3p, miR-376c-3p, miR-885-5p, miR-375, miR-486-5p, miR-411-5p, miR-133a-3p, miR-30a-5p). The meta-signature of identified miRNAs was functionally characterized by KEGG enrichment analysis. Twenty-four KEGG pathways were significantly enriched, and TGF-beta signaling was the most enriched signaling pathway. The highest number of meta-signature miRNAs was involved in the sphingolipid signaling pathway. Natural killer cell-mediated cytotoxicity was the pathway with most genes regulated by identified miRNAs. The rest of the enriched pathways in our miRNA list describe different malignancies and signaling. Conclusions: The identified miRNA meta-signature might be considered as a potential battery of biomarkers when distinguishing oral cancer tissue from normal, non-cancerous tissue. Further mechanistic studies are warranted in order to confirm and fully elucidate the role of deregulated miRNAs in oral cancer.

abstract = "Aim: It was the aim of the study to identify commonly deregulated miRNAs in oral cancer patients by performing a meta-analysis of previously published miRNA expression profiles in cancer and matched normal non-cancerous tissue in such patients. Material and methods: Meta-analysis included seven independent studies analyzed by a vote-counting method followed by bioinformatic enrichment analysis. Results: Amongst seven independent studies included in the meta-analysis, 20 miRNAs were found to be deregulated in oral cancer when compared with non-cancerous tissue. Eleven miRNAs were consistently up-regulated in three or more studies (miR-21-5p, miR-31-5p, miR-135b-5p, miR-31-3p, miR-93-5p, miR-34b-5p, miR-424-5p, miR-18a-5p, miR-455-3p, miR-450a-5p, miR-21-3p), and nine were down-regulated (miR-139-5p, miR-30a-3p, miR-376c-3p, miR-885-5p, miR-375, miR-486-5p, miR-411-5p, miR-133a-3p, miR-30a-5p). The meta-signature of identified miRNAs was functionally characterized by KEGG enrichment analysis. Twenty-four KEGG pathways were significantly enriched, and TGF-beta signaling was the most enriched signaling pathway. The highest number of meta-signature miRNAs was involved in the sphingolipid signaling pathway. Natural killer cell-mediated cytotoxicity was the pathway with most genes regulated by identified miRNAs. The rest of the enriched pathways in our miRNA list describe different malignancies and signaling. Conclusions: The identified miRNA meta-signature might be considered as a potential battery of biomarkers when distinguishing oral cancer tissue from normal, non-cancerous tissue. Further mechanistic studies are warranted in order to confirm and fully elucidate the role of deregulated miRNAs in oral cancer.",

AB  - Background: The genetic cause of most congenital anomalies of the kidney and urinary tract (CAKUT) cases remains unknown, therefore the novel approaches in searching for the common disease denominators are required. miRs regulate gene expression in humans and therefore have potentially therapeutic and biomarker properties. No studies thus far have attempted to explore the miRs in human CAKUT. We applied a new strategy to identify most specific miRs associated with CAKUT, in pediatric patients. Methods: Data from the whole genome expression, gathered from ureter tissue samples of 19 patients and 7 controls, were used for the bioinformatic prediction of miRs activity in CAKUT. We integrated microarray gene expression data and miR target predictions from multiple prediction algorithms using Co-inertia analysis (CIA) in conjunction with correspondence analysis and between group analysis, to produce a ranked list of miRs associated with CAKUT. The CIA included five different sequence based miR target prediction algorithms and the Co-expression Meta-analysis of miR Targets. For the experimental validation of expression of miRs identified by the CIA we used tissue from 36 CAKUT patients and 9 controls. The results of gene ontology (GO) analysis on co-expressed targets of miRs associated with CAKUT were used for the selection of putative biological processes relevant to CAKUT. Results: We identified 7 miRs with a potential role in CAKUT. The top ranked miRs from miRCos communities 4, 1 and 7 were chosen for experimental validation of expression in CAKUT tissue. The 5.7 fold increase of hsa-miR-144 expression in human tissue from CAKUT patients compared to controls (p = 0.005) was observed. From the GO we selected 7 biological processes that could contribute to CAKUT, which genes are potentially influenced by hsa-miR-144. The hsa-miR-200a, hsa-miR-183 and hsa-miR-375 werent differentially expressed in CAKUT. Conclusions: This study shows that integrative approach applied here was useful in identification of the miRs associated with CAKUT. The hsa-miR-144, first time identified in CAKUT, could be connected with biological processes crucial for normal development of kidney and urinary tract. Further functional analysis must follow to reveal the impact of hsa-miR-144 on CAKUT occurrence.

AB  - Urođene anomalije bubrega i urinarnog trakta (engl. Congenital Anomalies of the Kidney and Urinary Tract – CAKUT) su razlog nastanka čak polovine slučajeva terminalne bubrežne insuficijencije ali patofiziološka osnova ove bolesti još uvek nije poznata u potpunosti pa je samim tim otežana prevencija i terapija. U ovoj studiji je, upoređivanjem ekspresije celokupnog genoma u tkivu uretera pacijenata sa CAKUT-om i zdravih kontrola, identifikovano 78 diferencijalno eksprimiranih gena. Bioinformatičkom analizom je po prvi put zaključeno da postoji visok nivo kompleksnosti bioloških procesa i molekularnih puteva u tkivu čoveka koji su u CAKUT-u diferencijalno regulisani i čije važne interakcije se mogu predstaviti sa sedam molekularnih mreža, od kojih četiri sadrže gene sa funkcijama koje se direktno mogu asocirati sa CAKUT-om. Eksperimentalnom validacijom ključnih mreža qRT-PCR metodom utvrđen je povišen nivo iRNK za gene LCN2 (7,6 puta), PROM1 (8 puta) i SOSTDC1 (5,6 puta) i snižen nivo iRNK za gene RASD1 (4,5 puta), INA (3,3 puta) i TAC3 (6,6 puta) u tkivu uretera pacijenata u poređenju sa kontrolnim tkivom, koji mogu biti molekularni markeri za CAKUT. Ove mreže su ujedno i prikaz interakcija ključnih molekula u CAKUT-u i predstavljaju temelj budućih funkcionalnih studija. Primenom metode koja povezuje podatke sa genskog ekspresionog čipa i predikcije vezujućih mesta različitih miRNK iz više predikcionih algoritama, sa unapređenom rezolucijom, identifikovane su miRNK sa potencijalno povišenom ekspresijom u CAKUT-u u odnosu na zdrave kontrole. Validacijom ključnih miRNK qRT-PCR metodom je identifikovan povišen nivo miR-144 (5,7 puta) u tkivu uretera pacijenata u odnosu na kontrole, koji može biti molekularni marker za CAKUT.
AB  - Congenital anomalies of the kidney and urinary tract (CAKUT) are the cause for half of the cases with renal failure, but pathophysiological basis of this disease is not fully known. Therefore, the therapy and prevention of the disease is difficult. In this study, by comparing the whole-genome expression in the ureter tissue of patients with CAKUT and healthy controls, 78 differentially expressed genes were identified. By employing bioinformatical analysis it was concluded that there is a high level of complexity of biological processes and molecular pathways, differentialy regulated in CAKUT, whose important interactions can be represented with seven molecular networks, of which four contain genes with functions that can be directly associated with CAKUT. Experimental validation of key networks by qRT-PCR method identified elevated mRNA levels of LCN2 (7.6 fold), PROM1 (8 fold) and SOSTDC1 (5.6 fold), and decreased mRNA levels of RASD1 (4.5 fold), INA (3.3 fold) and TAC3 (6.6 fold) in the ureter tissue of the patients compared to control tissue, which may be molecular markers for CAKUT. These networks display the interactions of key molecules in CAKUT and provide the basis for future functional studies, as well. By applying the method that links microarray gene expression data and prediction of miRNA binding sites from several prediction algorithms, with enhanced resolution, miRNAs with potentialy upregulated expression in CAKUT compared to healthy controls were identified. Validation of key miRNAs by qRT-PCR method identified increased level of miR-144 (5.7 fold) in the ureter tissue of the patients compared to controls, which may be a molecular marker for CAKUT.

AB  - Aim: Chemokine CXC ligand 16 (CXCL16) has chemoattractive, adhesive and scavenging properties and may play a role in the formation of atherosclerotic lesions. However, studies of CXCL16 polymorphisms in patients with atherosclerosis are scarce. The missense polymorphisms I123T and A181V are potentially important factors in the regulation of presentation and shedding of the CXCL16 chemokine domain. The aim of this study was to analyze the association between I123T and A181V polymorphism haplotypes and the accumulation of carotid plaque as well as the effect of the haplotype on the CXCL16 mRNA expression in carotid plaques in patients with advanced atherosclerosis. Additionally, we performed a bioinformatic prediction analysis of the impact of CXCL16 protein sequence variation on CXCL16-CXCR6 interactions and analyzed the soluble CXCL16 plasma levels according to the CXCL16 haplotype. Methods: This study evaluated a total of 733 participants, including 283 controls and 450 patients with carotid atherosclerosis (CA) undergoing endarterectomy. Analyses of the polymorphisms and the gene expression were performed using real-time PCR. The soluble CXCL16 levels were measured with ELISA. Results: The missense allele haplotype, T123V181, was found to be significantly and independently associated with the occurrence of CA plaque (OR=1.27; 1.02-1.57, p=0.03). This haplotype was predicted to significantly change the CXCL16-CXCR6 interaction, compared to I123A181. Neither the CXCL16 mRNA expression in the human plaques nor the soluble CXCL16 plasma levels differed according to the haplotype. Conclusions: These results indicate that the CXCL16 T123V181 haplotype is a moderate genetic risk factor for the development of carotid plaque. Further functional and replication studies are needed to clarify the mechanisms by which this combination of alleles promotes advanced CA and validate its impact on disease progression.

abstract = "Aim: Chemokine CXC ligand 16 (CXCL16) has chemoattractive, adhesive and scavenging properties and may play a role in the formation of atherosclerotic lesions. However, studies of CXCL16 polymorphisms in patients with atherosclerosis are scarce. The missense polymorphisms I123T and A181V are potentially important factors in the regulation of presentation and shedding of the CXCL16 chemokine domain. The aim of this study was to analyze the association between I123T and A181V polymorphism haplotypes and the accumulation of carotid plaque as well as the effect of the haplotype on the CXCL16 mRNA expression in carotid plaques in patients with advanced atherosclerosis. Additionally, we performed a bioinformatic prediction analysis of the impact of CXCL16 protein sequence variation on CXCL16-CXCR6 interactions and analyzed the soluble CXCL16 plasma levels according to the CXCL16 haplotype. Methods: This study evaluated a total of 733 participants, including 283 controls and 450 patients with carotid atherosclerosis (CA) undergoing endarterectomy.

AB  - Chemokines and their receptors have become significant factors in atherosclerosis research. CXCL16 is a multifunctional agent located on a separate locus to all other known chemokines and binds only to its unique receptor named CXCR6. As a scavenger receptor, adhesion molecule, and chemokine, it quickly became an interesting target in atherosclerosis research as all its functions have a role in vascular pathology. The investigation of the role of CXCL16 in atherosclerosis, although shown in in vitro studies, animal knockout models, and CXCL16 gene polymorphisms, haplotypes, and circulating levels, still shows puzzling results. Genetic and epigenetic studies have just scratched the surface of research necessary for a better assessment of the significance and perspective of this marker in plaque development and progression. In this review, we will summarize current knowledge about CXCL16 in atherosclerosis. Additionally, we will point out the importance of bioinformatics tools for the detection of potentially new CXCL16 regulatory networks through microRNA activity. This review aims to provide a better understanding of the underlying mechanisms, define more specific biomarkers, and discover new therapeutic targets.

AB  - MicroRNAs (miRs) are short, non-coding RNAs that regulate gene expression by absolute or partial binding to mRNA, which results in transcript degradation and translation blocking. Atherosclerosis, as a complex and progressive disease, represents one of the main causes of cardiovascular clinical complications and even death. We applied co-inertia analysis (CIA) as a novel computation method, to determine which miRs are potentially associated with differences in gene expression levels originating from microarray data of early and advanced atherosclerotic plaque. As the CIA has not been applied in the field of atherosclerosis yet, we hypothesized that using CIA we can get novel information about the miRs that have significant role in early phase of disease or in severe phase of disease. The characteristic split in the data along the axes of performed CIA showed the difference in the gene expression pattern between early atherosclerosis and advanced atherosclerotic plaque. The advanced atherosclerotic plaques showed more homogenous gene expression pattern than early atherosclerosis samples. In early carotid lesions five out of five algorithms predicted miR-24, four out of five predicted miR-155, miR-145, and miR-100 as early active miRs. These miRs could be protective in plaque evolution context because they were not active in advanced plaques according to our results. They were reported previously as atheroprotective, which in a way represents confirmation of CIA application in atherosclerosis. We detected 13 new miRs which could be active in early plaque phenotype according to CIA prediction. In the advanced plaques we predicted miR-221, miR-222, miR-127 and miR-146 which were previously revealed to have atherogenic properties. In addition to miRs that have literature support, we also found new 8 miRs that, with described function so far, could present a novelty in research of atherosclerotic plaque evolution. All of these examples show that CIA results have a great potential to be of interest in future research in atherosclerotic plaque progression. We validated the applicability of CIA in the field of atherosclerosis, but we also found new interesting miR competitors that have strong potential to serve as markers and plaque development factors. These results should be experimentally confirmed in further research with ultimate goal to discover new mediators and blood markers, which could improve the prevention and therapy of this complex disease.
