AB  - Traditional methods in cell proliferation studies are based on immunohistochemical detection of proliferating cells in the target tissue. Since they are time consuming, optimization of novel, more efficient methods is important for large scale proliferation studies. In this study, we aimed to optimize the isolation of single epithelial rat forestomach cells for flow cytometry. As a marker of cellular proliferation we used the Ki-67 antibody to detect this nuclear protein expressed in proliferating cells. We also performed immunohistochemical detection of Ki-67 positive cells and propidium iodide staining to validate the results. 3-tert-butyl-4-hydroxyanisole was used as the positive control to ensure cellular proliferation. The results showed that isolation of epithelial cells with collagenase, trypsin and cell strainer ensures great cell viability (>95%) and the purity of the samples. Flow cytometry and immunostaining with the Ki-67 antibody indicated that 3-tert-butyl-4-hydroxyanisole treatment leads to a significant increase in proliferation. A significant positive correlation was observed between the results obtained by immunohistochemistry and flow cytometry, but the flow cytometric data had a smaller measurement error, suggesting the equal sensitivity and greater accuracy of this method. Propidium iodide staining showed that the percentage of cells in the G2+S phase of the cell cycle correlated positively with the percentage of Ki-67 positive cells assessed by flow cytometry, indicating that Ki-67 positive cells reflect an active dividing cell pool. We conclude that the isolation of forestomach epithelial cells described is a simple and reliable method for obtaining viable cells for use in flow cytometry. Compared to immunohistochemistry, flow cytometric detection of the Ki-67 antigen is equally sensitive, but much faster and provides more accurate results. © 2020, University of Zagreb, Facultty of Veterinary Medicine.

AB  - The study of cell proliferation is a useful tool in the fields of toxicology, pathophysiology and pharmacology. Cell proliferation and its degree can be evaluated using 5-bromo-2deoxyuridine which is incorporated into the newly synthesized DNA. The aim of this study was the optimization of subcutaneous application of 5-bromo-2-deoxyuridine implantation for continuous and persistent marking of proliferating cells in the rat forestomach. 3-tert-Butyl-4-hydroxyanisole was used as the agent that ensures cell proliferation. In order to determine the optimal dose for proliferating cells labeling, 5-bromo-2-deoxyuridine doses of 50 mg, 100 mg, 200 mg or 350 mg were implemented 2 days prior to sacrifice by flat-faced cylindrical matrices. Immunohistochemical analysis using 5-bromo-2-deoxyuridine in situ detection kit was performed for the detection of 5-bromo-2-deoxyuridine labeled cells. The results showed that for adult rats, the optimum 5-bromo-2-deoxyuridine dose is 200 mg per animal for subcutaneous application. The here described manner of 5-bromo-2-deoxyuridine in vivo labeling provides a simple, efficient, and reliable method for cell labeling, and at the same minimizes stress to animals.

AB  - We present herein a case report style article on a rare advanced triple-negative breast cancer (TNBC) patient with 6-month disease-free interval, and 10-month overall survival. Our results demonstrate that the poor clinical outcome of this patient was associated with pronounced, more than fivefold higher, overexpression of both cFOS and TGF-beta 1 proteins in its metastatic nodal tissue extracts, when compared with the values of the two non-TNBC controls (with zero disease-free interval and overall survival). This original observation suggests, for the first time, that both the cFOS and TGF-beta 1 may be considered as a pair of biomarkers for an early assessment of poor prognosis for TNBC patients. The possible clinical implication of this observation is discussed.

AB  - Chronic oxidative stress plays an important role in depression. The aim of present study was to examine the stress-induced changes in serum corticosterone (CORT) levels, cytosolic protein carbonyl groups, malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO) and total superoxide dismutase (SOD) activity in the prefrontal cortex versus hippocampus of male Wistar rats exposed to acute (2 h of immobilization or cold), chronic (21d of social isolation) stress, and their combination (chronic + acute stress). The subcellular distribution of nuclear factor-kappa B (NF-kappa B) and cytosolic cyclooxygenase 2 (COX-2) protein expressions were also examined. Depressive- and anxiety-like behaviors were assessed via the forced swim, sucrose preference, and marble burying tests in chronically isolated rats. Although both acute stressors resulted in elevated CORT, increased MDA in the prefrontal cortex and NF-kappa B activation accompanied by increased NO in the hippocampus were detected only following acute cold stress. Chronic isolation resulted in no change in CORT levels, but disabled appropriate response to novel acute stress and led to depressive- and anxiety-like behaviors. Increased oxidative/nitrosative stress markers, likely by NF-kappa B nuclear translocation and concomitant COX-2 upregulation, associated with decreased SOD activity and GSH levels, suggested the existence of oxidative stress in the prefrontal cortex. In contrast, hippocampus was less susceptible to oxidative damage showing only increase in protein carbonyl groups and depleted GSH. Taken together, the prefrontal cortex seems to be more sensitive to oxidative stress than the hippocampus following chronic isolation stress, which may be relevant for further research related to stress-induced depressive-like behavior.

AB  - The c-Jun NH2-terminal kinases (JNKs) are important stress-responsive kinases. They regulate cellular activities by sequential phosphorylation and activation through a mitogen-activated protein kinase cascade, whereas JNKs activation is altered in response to various stressors. In the present study, we used immunoblotting to assess the effect of 21 day of social isolation as the chronic stressor, either sole and in combination with 2 h of acute immobilization or cold (4A degrees C) stress on circulating corticosterone level and phosphorylation status of p46 (phospho-p46/total p46) and p54 (phospho-p54/total p54) JNK isoforms in the cytosolic and nuclear fraction of the prefrontal cortex and hippocampus of male Wistar rats. Also, the phosphorylation status of JNK nuclear down-stream target c-Jun (p-c-Jun/c-Jun) on Ser63 was examined. Both acute stressors with elevated CORT levels led to increased phosphorylation status of cytosolic p54 JNK isoforms but not p46 JNK isoforms only in the hippocampus and no change in phosphorylation status of c-jun in both brain regions. Chronic isolation with unaltered CORT level and reduced responsiveness to novel acute stressors, led to unchanged or reduced phosphorylation status of p46 and p54 JNK isoforms in both fractions and both brain regions, whereas the decrease of c-Jun phosphorylation status was found only in the prefrontal cortex. Our results suggest that compromised JNKs activation following chronic isolation may lead to interruption of JNK signaling, which could be related with neuropsychiatric disorders such as depression or long-lasting neuronal remodeling.

AB  - Stimulation of glutamate receptors induces neuronal nitric oxide (NO) release,
which in turn modulates glutamate transmission. The present study evaluated the
effects of acute, chronic or combined stress on NO production via the accumulation
of nitrite, the stable metabolite of NO, in the prefrontal cortex and hippocampus of
male Wistar rats. Given that glutathione (GSH) plays a critical role in protecting
cells from oxidative stress, as well as maintaining the thiol redox state, GSH levels
in cytosolic fractions of both brain structures were examined. A significant increase
in nitrite levels was obtained after 3 weeks of chronic isolation stress, followed by
combined stresses (chronic + acute stress). Moreover, GSH levels were
significantly decreased after chronic and both combined stresses in both brain
structures. Our data support the idea that GSH might represent an important buffer
of NO toxicity in the brain, indicating that compromised redox buffering controlled
by GSH makes neuronal cells susceptible to endogenous physiological flux of NO.

which in turn modulates glutamate transmission. The present study evaluated the
effects of acute, chronic or combined stress on NO production via the accumulation

male Wistar rats. Given that glutathione (GSH) plays a critical role in protecting
cells from oxidative stress, as well as maintaining the thiol redox state, GSH levels

AB  - Nitric oxide (NO) has been identified as a source of oxidative/nitrosative stress that
is known to oxidatively modify DNA, lipids and proteins. One such modification is
the addition of carbonyl groups to amino acid residues in proteins. Therefore, the
aim of our study was to examine the effects of acute, chronic or combined stress on
NO production and protein carbonyl content in the cytosolic fraction of rat liver.
Since NO is a highly reactive molecule, the levels of NO metabolites (nitrates and
nitrites) as markers of stable end products of NO metabolism were measured. Both
acute stresses showed unchanged nitrite levels while only acute IM stress led to an
increased level of the carbonyl group. The NO metabolites and protein carbonyl
content were increased by chronic isolation and remained upregulated after
combined stress. These data indicate that chronic isolation stress with increased
NO metabolites led to nitrosative stress, whereby accumulation of oxidized
proteins in the liver may induce progressive liver damage.

AB  - In this study, we analysed pellets from long-eared owls (Asio otus) collected from four localities in Belgrade (Serbia). The pellets contained the remains of prey, namely voles (Arvicola terrestris) and field mice (Apodemus agrarius). The concentrations of 14 elements (Ca, P, Mg, Na, K, Fe, Zn, Sr, Ba, Mn, Ti, Cu, Si, B) were evaluated in whole pellets and in samples containing only bone tissue, which were dissected from the whole pellet. The increased levels of certain elements, including Mn, Zn, Ba, Cu and radioactive K-40, indicate contamination of the soil by various sources, such as industrial plants and agricultural practices. From the results presented in this article, we suggest that the analysis of owl pellets may indicate the quality of the local environment.

AB  - In this study, we investigated the in vitro effects of metal ions on Mg2+-ATPase activity in isolated membranes from rat uterus. The effects of increasing concentrations of metal salts (CrCl2, CuSO4, HgCl2 and ZnSO4) show sigmoidal and almost complete inhibition relative to the control enzyme activity. According to the IC50, the ATPase possesses greater sensibility to Zn2+ GT Cu2+ congruent to Cr3+ congruent to Hg2+, while other metal salts exhibit the following inhibition: CdCl2 55%, CsCl 64.5% and SrCl2 58%. Here we demonstrated that the physicochemical properties of these metals are of importance in defining possible mechanisms of binding and decrease of enzyme activity.

AB  - OBJECTIVE: To use cytoplasmic tissue extract as a new specimen source to quantify transforming growth factor beta 1 (TGF beta 1) protein in metastatic axillary lymph node tissue (ALNT) of breast cancer (BC) patients and to confirm the feasibility of this approach in a prospective pilot study on a subgroup of patients with invasive BC. STUDY DESIGN: The 6 selected malignant and autologous nonmalignant pairs of ALNT were fractionated, under special preanalytical, nonaggressive/nondenaturing conditions, to obtain respective cytoplasmic extracts for TGF beta 1 detection by the Quantikine (R and D Systems Inc., Minneapolis, Minnesota, U.S.A.) enzyme-linked immunosorbent assay kit. RESULTS: The data indicated a highly significant (r=0.973054) positive linear correlation between the TGF beta 1 concentration and total protein concentration in cytoplasmic extract of metastatic ALNT. The subsequent patients pilot study, performed strictly before any clinicopathologic factors were accessible, revealed significantly (p LT 0.01) elevated TGF beta 1 in malignant ALNT (median value: 1.05 ng/mg protein, range: 0.67-3.6 ng/mg protein, n=6) vs. autologous nonmalignant ALNT controls (median value: 0.48 ng/mg protein, range: 0.29-0.90 ng/mg protein, n=6). This elevation was correlated with the number of metastatic axillary lymph nodes with respect to the total and was consistent with an increase in size of tumor deposits in axillary lymph nodes. CONCLUSION: Our data provide for the first time suggestive evidence that the TGF beta 1 level in cytoplasmic extracts of metastatic ALNTs may be a promising bio-marker of invasiveness for BC patients. Confirmatory, large-scale studies are needed to evaluate possible implications of this putative biomarker in BC diagnosis and treatment. (Anal Quant Cytol Histol 2009;31:288-295)

AB  - The aim of the present study was to define the stress-induced pattern of cytosolic glucocorticoid receptor (GR) and Hsp70 protein in the liver of male Wistar rats exposed to different stress models: acute (2 h/day) immobilization or cold (4 degrees C); chronic (21 days) isolation, crowding, swimming or isolation plus swimming and combined (chronic plus acute stress). Changes in plasma levels of corticosterone were studied by radioimmunoassay (RIA). The results obtained by Western immunoblotting showed that both acute stressors led to a significant decrease in cytosolic GR and Hsp70 levels. Compared to acute stress effects, only a weak decrease in the levels of GR and Hsp70 was demonstrated in chronic stress models. Chronically stressed rats, which were subsequently exposed to novel acute stressors (immobilization or cold), showed a lower extent of GR down-regulation when compared to acute stress. The exception was swimming, which partially restores this down-regulation. The observed changes in the levels of these major stress-related cellular proteins in liver cytosol lead to the conclusion that chronic stressors compromise intracellular GR down-regulation in the liver.

AB  - This paper reports results of gamma and alpha spectrometric measurements for mosses, lichens, fungi and soil samples from areas in the Balkans targeted by depleted uranium (DU). Samples were collected in 2002 and 2003 in the vicinity of several villages, principally Han Pijesak: (Bosnia and Herzegovina, hit by DU in 1995) and Bratoselce (South Serbia, hit by DU in 1999) and in lesser numbers from Gornja Stubla, Kosovo (which is identified as a high natural radon/thoron area) and Presevo close to the Kosovo border. In the course of gamma spectrometric measurements some results suggested samples with unusual high uranium contents which might be considered to be a signature for the presence of DU, although many samples had very high detection limits. Alpha spectrometric measurements directly proved the presence of DU for five samples, all from directly targeted places. These were samples of mosses, lichens and soil. For some samples homogeneity tests were applied which showed a rather even distribution of DU in these samples. No trace of DU was found in any sample from a dwelling. (C) 2008 Elsevier Ltd.

AB  - The effects of increasing concentrations of HgCl2 on rat uterine plasma membrane ecto-ATPase activity, in presence and absence of ethylenediamine tetra acetic acid (EDTA) were studied. The aim was to examine the ability of EDTA to prevent mercury induced inhibition of ecto-ATPase activity. Our results show that addition of 1mmol/l EDTA to the reaction mixture potentiates Hg2+ induced inhibition of enzyme activity. We may concluded that formation of the HgEDTA complex increased capacity of Hg2+ to inhibit enzyme activity.

AB  - Cranial radiotherapy (CRT) is an effective way to prevent CNS relapse in children with acute lymphoblastic leukemia (ALL). However, CRT also has serious side effects on normal tissues, including long-term neuroendocrine disturbances. In order to test this clinical protocol on animals, we examined the effects of CRT (10 Gy) on the level of mRNA for glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) in the hippocampus of 8-days-old rats. Irradiation rapidly stimulated GR gene expression in a time-dependent manner, whereas the time-course of MR mRNA expression showed no statistically significant changes. At postnatal day 42, the level of GR mRNA was diminished while the level of MR mRNA remained unchanged compared to matched controls. Dexamethasone suppression test (DST) revealed the altered nucleocytoplasmic shuttling of activated GR after CRT in 42-days-old rats, as a long-term consequence of gamma irradiation.

AB  - Background: The role of circulating TGF-beta(1) in prognosis of breast cancer (BC) was investigated with an intention to define TGF-beta(1)-dependent high risk and low risk subsets of patients. Methods: Fifty three BC patients of all clinical stages and 37 healthy donors (HD) were analyzed for plasma TGF-beta(1) by the T beta RII receptor-based Quantikine TGF-beta(1) ELISA kit. Results: The plasma TGF-beta(1) level of Stage I/II disease (median: 0.94 ng/ml; n=10)) remained close to HD (median: 1.30 ng/ml; n = 37; p GT 0.1). In contrast, Stage III/IV disease (median: 2.34 ng/ml; n=43) exhibited highly significant TGF-beta(1) elevation (p LT 0.001) relative to HD. Further analysis revealed that TGF-beta(1) increase was predominantly attributed to Stage IV, metastatic disease patients (Q3=4.23 ng/ml) rather than to the group Stage III/IV (Q3=3.58 ng/ml). Using the plasma TGF-beta(1) concentration of 3.00 ng/ml as the cut-off value, two subgroups of patients were formed. Overall 2-year survival of the first subgroup, having elevated plasma TGF-beta(1) ( GT 3.00 ng/ml; n=10), was 10%. This was significantly decreased (p LT 0.05) compared to 52% survival observed for the second subgroup of patients with plasma TGF beta(1) values close to HD ( LT 3.00 ng/ml, n=19). Conclusion: We have performed a pilot study to determine the relationship between overall survival and TGF-beta(1) concentration in the blood of metastatic breast cancer patients. The survival was significantly reduced in the patients with elevated plasma TGF-beta(1) levels compared to that of the patients with plasma TGF-beta(1) levels close to normal. We propose that plasma TGF-beta(1) concentration may be a new tumour marker attributed to the presence of metastatic BC cells that may be used in selection of metastatic BC patients with poor prognosis.

AB  - The effect of drugs from the class of cardiac (methyldigoxin, verapamil, propranolol), antiepileptic ( carbamazepine), sedative (diazepam) and antihistaminic (promethazine) drugs on Na,K-ATPase activity of plasma membranes was studied in rat brain synaptosomes. Methyldigoxin in a concentration of 0.1 mmol/l inhibits enzyme activity by 80%. Verapamil, propranolol and promethazine in concentrations of 20, 20 and 2 mmol/l respectively, entirely inhibit the ATPase activity. Carbamazepine and diazepam in concentrations of 0.02-60 mmol/l have no effect on the activity of this enzyme. According to the drug concentrations that inhibit 50% of enzyme activity (IC50), the potency can be listed in the following order: methyldigoxin GT GT promethazine GT verapamil GT = propranolol. From the inhibition of commercially available purified Na, K-ATPase isolated from porcine cerebral cortex in the presence of chosen drugs, as well as from kinetic studies on synaptosomal plasma membranes, it may be concluded that the drugs inhibit enzyme activity, partly by acting directly on the enzyme proteins. Propranolol, verapamil and promethazine inhibitions acted in an uncompetitive manner. The results suggest that these three drugs may contribute to neurological dysfunctions and indicate the necessity to take into consideration the side effects of the investigated drugs during the treatment of various pathological conditions.

AB  - The in vitro effect of digoxin, verapamil, propranolol, carbamazepine, diazepam and promethazine were investigated on the ecto-ATPase activity of synaptosomal plasma membranes from the rat brain. ATP hydrolyzing activities of the enzyme were not affected by digoxin while the use of all other drugs resulted in significant and dose-dependent ihibition in ATP hydrolysis. According to values Of IC50 and K-iapp, the order of inhibitory potency of the drugs applied was: diazepam GT promethazine GT verapamil GT propranolol GT GT carbamazepine. Kinetic analysis of the nature of the ATPase inhibition revealed that it resulted from a direct action of drugs on the enzyme protein. The aim of the present study was to determine the potential neuromodulatory side effects of the drugs investigated. The results achieved indicated that all investigated drugs, except digoxin, may modulate neuronal activities via the purinergic receptors P2 by increasing extracellular concentrations of ATP as a consequence of inhibition of the ecto-ATPase activity. Our findings indicate that it may be useful to take into consideration the possible side effects of the investigated drugs, when they are used in treatment of different pathologies, particularly in the treatment of epilepsy by carbamazepine and diazepam.

AB  - The in vitro effects of cadmium and mercury were investigated on the Mg2+-ATPase activity of plasma membranes from the rat ovary and uterus. ATP hydrolyzing activities were significant and dose-dependent-inhibited in both plasma membrane preparations by both metals. According to the IC50 and apparent K-i, Cd2+ was most potent in the ovary, while Hg2+ was most potent in the uterus. In ovaries and uterus,Cd2+ inhibits competitively, while Hg2+ inhibits noncompetitively in both organs. The observed inhibition was a consequence of direct action of the chosen metal ions on the enzyme protein and by decreasing ATP hydrolysis, Hg2+ and Cd2+ may affect mammalian fertility.

AB  - The in vitro effect of estradiol on flux of Ca2+ in the synaptosomal mitochondria from nucleus caudatus and hippocampus of chronically ovariectomized female rats was examined. No effect of estradiol on Ca2+, influx through ruthenium red-sensitive channels was found. Estradiol, at a concentration of 0.05-5 nmol/L for nucleus caudatus and 0.5-5 nmol/L for the hippocampus, decreased Na-dependent Ca2+ efflux about 25%.

AB  - Ions of zinc and cooper represents micro elements present in all organisms but they can be accumulated in various tissues from the environment by food or pollution. In this work we examined the effects of chloride salts of Cu2+ and Zn2+ on the activity of ecto-ATPase, integral plasma membrane protein, in brain and ovarian cells. Both ions exhibit similar effects on brain or ovarian enzyme activity. Cooper in brain and ovary totally inhibits enzyme activity at the concentration of 1 mM and 0.1 M respectively. IC50 for brain is 36 µM while in ovary it is 192 µM. Zinc inhibits in both tissues 50% of the control enzyme activity at concentrations of 1 mM in brain and 0.1 M in ovary with IC50 of 1mM and 14 mM respectively. These metals possess an affinity for -SH groups in the enzyme protein, may replace Mg2+ in enzyme substrate, MgATP or to bind for enzyme substrate site. According to the total inhibition of ecto-ATPase activity by Cu 2+, it may be proposed that its site of action is on the substrate or substrate binding site, while Zn2+ modulates enzyme activity by acting on the –SH or S-S groups of the enzyme. Inhibiting or decreasing ecto-ATPase activity in brain and ovary, these two metal ions may be toxic and seriously disturb the proper functioning of the investigated tissues.

AB  - Novel antineoplastic agents, 8-chloroadenosine 3,5-monophosphate (8-Cl-cAMP) and tiazofurin (TR), have been shown to be effective against different malignant cells. Through specific mechanisms of action they modulate the cellular signal transduction pathway, thereby causing growth inhibition, cell differentiation, and apoptosis. The aim of this work was the in vitro study of either 8-Cl-cAMP or TR effects on B16/F10 and B16/C3 mouse melanoma cell growth and cell death. Significant cell growth inhibition was obtained after the application of 8-Cl-cAMP or TR. The presence and number of apoptotic cells was evaluated using agarose gel electrophoresis and flow cytometry. The number of apoptotic nuclei, after treatment with antineoplastic agents, did not significantly change in B16/F10 cells, although it did show a significant increase in B16/C3 cells. The expression of c-myc did not significantly change in B16/F10 cells after treatment with 8-Cl-cAMP or TR. The same results were obtained in B16/C3 cells after treatment with 8-Cl-cAMP. The level of c-myc expression showed a significant increase in B16/C3 cells after treatment with TR. Concerning the effects that the analyzed agents exhibited on melanoma cells and other cancer cells, further preclinical studies of these drugs will potentially lead to better understanding of the molecular mechanisms of their action and finally more efficient therapeutic approaches to malignant diseases.
