AB  - The glucocorticoid receptor (GR) signal transduction and transcriptional regulation are efficiently recapitulated when GR is expressed in Saccharomyces cerevisiae. In this report we demonstrate that the in vivo GR phosphorylation pattern, hormone dependency and interdependency of phosphorylation events were similar in yeast and mammalian cells. GR phosphorylation at S246 exhibited inhibitory effect on S224 and S232 phosphorylation, suggesting the conservation of molecular mechanisms that control this interdependence between yeast and mammalian cells. To assess the effects of GR phosphorylation the mutated GR derivatives T171A, S224A, S232A, S246A were overexpressed and their transcriptional activity was analysed. These receptor derivatives displayed significant hormone inducible transcription when overexpressed in S. cerevisiae. We have established an inducible methionine expression system, which allows the close regulation of the receptor protein levels to analyse the dependence of GR function on its phosphorylation and protein abundance. Using this system we observed that GR S246A mutation increased its activity across all of the GR concentrations tested. The activity of the S224A and S246A mutants was mostly independent of GR protein levels, whereas the WT, T171A and S232A mediated transcription diminished with declining GR protein levels. Our results suggest that GR phosphorylation at specific residues affects its transcriptional functions in a site selective manner and these effects were directly linked to GR dosage.

AB  - The effect of dexamethasone (DEX) on glucocorticoid receptor (GR)-mediated gene expression was examined in the brain of young and aged rats. Electrophoretic mobility shift assays showed that DEX treatment led to an increase of glucocorticoid response element (GRE) binding activity in aged rats, whereas in young animals GRE binding activity was decreased. Western blot analysis and reverse transcriptase polymerase chain reaction confirmed that, in aged animals, the GR mRNA and the GR protein levels were increased on DEX treatment. The binding activity of GRE activating protein-1 (AP-1) site and cross-competition analysis demonstrated specific pattern of expression during the ageing and DEX treatment, suggesting that GR modulates the activity of transcription factors AP-1 (Fos/Jun proteins) through protein-protein interaction. On the basis of these results, it can be concluded that the composition of transcriptional complexes that bind to GRE and AP-I regulatory elements changes upon DEX treatment in an age-specific manner.

AB  - The aim of this work is the in vitro study of human melanoma cell growth modulation after irradiation with protons. Confluent cell monolayers were irradiated with single doses ranging from 1 to 20 Gy, using proton beams having energy of 22.6 MeV at the target. 48 hours after irradiation, cell growth, cell cycle analyses and initiation of cell death were followed. The obtained results were compared with the effects of glucocorticoid hormones. The inhibition of melanoma cell growth was observed, especially after single application of 12 and 16 Gy. Cell cycle analyses of melanomas after proton irradiation, have shown the G2/M arrest of irradiated cells corresponding with the increase of applied dose. The flow cytometric analysis has shown presence of apoptotic nuclei. Glucocorticoid treatment has shown modest melanoma cell growth inhibition, cell cycle arrest in G2/M phase and ladder pattern on agarose gel electrophoresis.

AB  - The subsynaptosomal distribution and specific binding of 17 beta -estradiol in vitro to mitochondria isolated from presynaptic nerve endings of female rat brain were examined. 17 beta -Estradiol is (i) distributed unequally in synaptosomes and mitochondria posses the highest capacity to bind estradiol with respect to the available amount of the hormone. (ii) Estradiol binds specifically to isolated synaptosomal mitochondria. A Michaelis-Menten plot of specific binding was sigmoidal within a concentration range of 0.1-5 nM of added estradiol, with a saturation plateau at 3 nM. Binding of higher estradiol concentrations demonstrated an exponential Michaelis-Menten plot, indicating non-specific binding to mitochondria. V-max, and K-m for the sigmoidal-shape range were estimated as 46 +/- 6 fmol of estradiol/mg of mitochondrial proteins and 0.46 +/- 0.07 nM free estradiol respectively. (iii) Esstradiol binding is not affected by the removal of ovaries. The results show that inhibition of Na-dependent Ca2+ efflux from mitochondria by estradiol occurs according to an affinity change of the translocator for Na+, at the same estradiol concentrations that show specific binding to mitochondrial membranes. These data imply that physiological concentrations of estradiol, acting on mitochondrial membrane properties, extragenomically modulate the mitochondrial, and consequently the synaptosomal content of Ca2+, and in that way exert a significant change in nerve cell homeostasis.

The experimental conditions were focused on analyzing the effects of irradiation on the periphery of tumour that can be, in clinical practice, close to critical organs. Confluent cell monolayers were irradiated with single doses ranging from 1 - 20 Gy, using proton beams having an energy of 22.6 MeV at the target. Antiproliferative effect of protons, cell cycle analysis and initiation of cell death, were followed 48 hours after irradiation. The inhibition of melanoma cell growth was observed, especially after single application of 12 and 16 Gy. Cell cycle analysis and cell viability have shown the G2/M and G1/G0 arrest of irradiated cells correlating with the increase of the applied dose. The flow cytometric analysis has shown presence of apoptotic nuclei. These data demonstrate that irradiation with protons, under the chosen experimental conditions, have significant effects on melanoma cell growth inhibition being dose dependent, G2/M cell cycle arrest and appearance of apoptotic nuclei, even 48 hours after irradiation. The results obtained may help the understanding of the relationship between cell proliferation, death and cell cycle regulation of melanomas after proton irradiation.

AB  - Abundant evidence indicates that ATP and adenosine act as neurotransmitters or co-transmitters, influencing nerve cell physiology in various ways. Therefore, regulation of ATP-metabolizing enzymes is essential for the normal development and function of neuronal tissue. In the present study we have examined the effect of gonadal (OVX) or adrenal (ADX) steroid hormone deprivation on the activity and expression of synaptic membrane ecto-ATPase in three extrahypothalamic brain areas of female rats, primarily not associated with reproductive function. It was shown that OVX significantly increased ecto-ATPase activity and the relative abundance of this enzyme in the hippocampal (Hip) and caudate nucleus (CN), but not in brain stem (BS) membrane preparations. ADX was followed by an upregulation of the enzyme activity and its relative abundance in all the brain areas investigated. The highest enzyme activity and the most profound effects of OVX and ADX were detected in the CN. The results obtained indicate that ADX and OVX upregulate the expression of ecto-ATPase, potentiating the production of adenosine in synaptic cleft thus modulating the activity of numerous neurotransmitter systems in distinct areas of the CNS.

It was shown that OVX significantly increased ecto-ATPase activity and the relative abundance of this enzyme in the hippocampal (Hip) and caudate nucleus (CN), but not in brain stem (BS) membrane preparations. ADX was followed by an upregulation of the enzyme activity and its relative abundance in all the brain areas investigated. The highest enzyme activity and the most profound effects of OVX and ADX were detected in the CN. The results obtained indicate that ADX and OVX upregulate the expression of ecto-ATPase, potentiating the production of adenosine in synaptic cleft thus modulating the activity of numerous neurotransmitter systems in distinct areas of the CNS.",

AB  - The goal of this study was to provide data on the dose-dependent production of dicentrics and micronuclei in human lymphocytes irradiated with 22.6 MeV protons and to estimate the possible contribution of intracellular superoxide dismutases (SOD) to the relative biological effectiveness (RBE) of protons. For the dose-response study, heparinized whole blood of a healthy volunteer was irradiated with protons and Xrays employing radiation doses of 0.5-4 Gy. Three biological endpoints were analyzed: chromosomal aberrations, micronuclei, and specific activity of cytosolic (CuZnSOD) and mitochondrial (MnSOD) superoxide dismutases in harvested human blood cells. Dicentric dose-response curves fit a linear-quadratic form (alpha = 0.094 +/- 0.006, beta = 0.032 +/- 0.001) induced with X-rays and (alpha = 0.119 +/- 0.057, beta = 0.029 +/- 0.014) for 22.6 MeV protons. Protons were more effective than X-rays in producing exchanges, particularly at 0.5 and 1 Gy. In contrast to X-ray irradiated samples where a significant increase in the specific activity of MnSOD was recorded (up to a radiation dose of 1 Gy), irradiation with protons markedly reduced its activity. As a consequence of the reduced activity of MnSOD, the chromosomal dose-response curve became quadratic. The RBE for dicentrics varies with dose (from 2.2 to 1.01) and reduced activity of MnSOD is an important contributor to the RBE of protons. SODs, particularly MnSOD, play an important role in defending DNA from reactive oxygen species. A reduced activity of SOD, particularly MnSOD, is an important contributor to the RBE of protons.

AB  - Hormonal requirements for full hepatic expression of alpha(2)-macroglobulin (alpha(2)M), alpha(1)-acid glycoprotein (AGP), haptoglobin (Hp) and gamma-fibrinogen (Fb) were assessed at the level of mRNA. Prior to exposure to turpentine-induced inflammation, rats were either depleted of glucocorticoids by adrenalectomy or supplemented with an excess of dexamethasone. Adrenalectomy alone did not affect the basal level of acute phase protein (APP) expression except for alpha(2)M mRNA, the level of which was enhanced. In contrast, dexamethasone treatment alone promoted full induction of alpha(2)M, significant, but not maximal increase of AGP and Hp mRNAs and suppression of Fb. In adrenalectomized rats, acute phase (AP)-cytokines, released in response to inflammation, promoted full expression of Fb and Hp and increased the level of AGP mRNA whereas alpha(2)M mRNA remained at the basal level. Inflammation in dexamethasone pretreated rats elicited changes which, in comparison to mRNA values for dexamethasone unpretreated inflamed rats, were seen as overexpression of alpha(2)M, full expression of AGP and incomplete expression of Hp, whereas Fb mRNA remained at the basal level. These data suggest that glucocorticoids are the principal inducers of a(2)M and AP-cytokines of Fb. For full induction of AGP, additive actions of glucocorticoids and AP-cytokines are required whereas expression of Hp is predominantly controlled by AP-cytokines. (C) 1998 Elsevier Science Ltd.

AB  - Activities of superoxide dismutases MnSOD and CuZnSOD were measured in appropriate subcellular fractions prepared from livers of intact and long-term gonadectomized (GX) rats of both sexes, and of GX female and male rats injected sc with a single dose of 5 mu g estradiol benzoate (EB) or 2 mg progesterone (P). In female livers, MnSOD activity did not vary significantly during the estrous cycle, declined after gonadectomy in comparison to proestrus, and was steady in GX females treated with EB or P. The activity of CuZnSOD was lowered at proestrus and elevated after removal of the ovaries in comparison to proestrus value. EB suppressed, and P elevated CuZnSOD activity in GX females. In the liver of male rats, MnSOD was not affected by gonadectomy nor by EB and P treatments. CuZnSOD activity was reduced following orchiectomy and enhanced in GX mates following treatment with P, while EB had no effect. These results suggest that P and EB modulate the activity of CuZnSOD and do not affect MnSOD in the rat liver. The modulatory effects are elicited by P in the males and by P and EB in the females.

AB  - The goal of this study was to examine the possible effects of the insulin on the functional properties of the glucocorticoid receptor (GR), in the rat liver, as well as its equilibrium binding constant (Kd) and number of binding sites (q), in order to contribute to elucidation of the molecular basis of the relationship between insulin and glucocorticoids in regulation of cell processes. Biological consequences of their interactions were judged on the basis of changes in GR as well as in the activity of Tryptophan oxygenase (TO). The experiments were perfomed on male nonadrenalectomized Wistar strain rats, treated by streptozotocin as well as adrenalectomized animals These group of animals were injected by insulin (25ug/100g b.w.) 18 hours before analysis. The obtained results have shown that the Kd in all experimental groups of animal was in the interval: 1.87-4.027nM. However, the injected insulin in all experimental groups increased the number of GR, while in streptozotocin treated rats, this increase was 1.5 fold, compared to the values obtained for corresponding controls. TO activity was increased (2-3 fold), in liver of insulin treated rats, except in the case of adrenalectomized animals, while the enzyme activity in streptozotocin treated rats was up to 3 fold, in respect to the appropriate control value. These evidences suggest that mechanisms of cooperative effects of insulin and glucocorticoid on regulation of cell function involve the modulation of hormone signals transmited through changes in number and functionality of GR proteins.
