Introduction. Cadmium is a toxic heavy metal with devastating effects on most organ systems. After absorption, cadmium is transported throughout the body, primarily by binding to proteins by metallothioneins. It is believed that the mechanisms of cadmium-induced transformation arise due to the disruption of zinc-dependent cellular processes. This part is due to the structural and physical similarities between zinc and cadmium. More than half of the incoming cadmium is deposited in the liver and kidneys. The rest part is distributed throughout other organs and their systems. Materials and methods. In total, 40 white outbred rats of both sexes weighing 170-230 g were used in the experiment; they were formed into four experimental groups of 10 animals each, depending on the dose of the injected toxicant. Liver tissue samples were used as research materials, in the homogenate of which the quantitative content of Cd and Zn was determined, as well as the mRNA level of the MT1 and ZIP1 genes. Results. It was found that the most pronounced activity of the MT1 gene in liver tissues was achieved when animals were administered cadmium chloride at a dose of 0.1 mg/kg (2.69 ± 0.37; p = 0.017), while the multiplicity of expression of the ZIP1 gene showed the maximum value of the level of transcripts with the minimum dose of toxin (2.70 ± 0.37; p = 0.007). It was also revealed that the highest concentration of zinc in the liver tissue was observed with the introduction of cadmium chloride at a dose of 0.1 mg/kg (33.84 ± 0.53; p <0.001), and the concentration of cadmium increased along with an increase in the dose of the toxicant (0, 0049 ± 0.0003; 0.0203 ± 0.0024; 0.664 ± 0.007; 0.76 ± 0.0089). Conclusion. Thus, a comprehensive study of the expression of genes for metallothioneins and zinc transporters can be used as a biomarker of poisoning with cadmium and its compounds.

The aim of the study – to learn the expression of VEGF and HIF-1α in physiological, hyperplastic, atypical endometrium at different ages of women. Materials and Methods. Evaluation of VEGF expression and HIF-1α performed in endometrial tissue samples in 458 women of late reproductive, perimenopausal and postmenopausal age. Expression of VEGF and HIF-1α was performed at the mRNA level by polymerase chain reaction of cDNA obtained by reverse transcription. The results were processed by the method of variation statistics with the assessment of reliability according to the Student's criterion using standard computer systems. Results and Discussion. Analyzing the data of the presented work, higher VEGF expression rates were found in atypical hyperplasia in all age categories, but probably higher rates were found in the postmenopausal period, in atypical endometrial hyperplasia, which indicates the need for vigilance in detecting this process in the appropriate age category. Studies have shown that HIF-1α can potentiate the activation of vasomotor genes that are required for the vascular response to hypoxia. These studies demonstrate the informativeness of the method of determining HIF-1α in the examination of patients with endometrial hyperplastic processes (EHP). The introduction of this method in practical medicine will not only understand the details of the changes occurring in the body (pathological, physiological), but also develop strategic maneuvers for possible therapeutic or surgical treatments. Conclusions. Expression of VEGF and HIF-1α levels in endometrial tissue cells as a marker can be a promising method for diagnosing the risk of proliferative conditions and their prognosis, especially in combination with other markers that characterize immunohistochemical and molecular genetic cellular parameters. Hypoxia and its relationship with indicators of angiogenesis may have some promising significance. Because the development of pathological conditions develops at a certain stage of hypoxic conditions. Under certain conditions, as a result of disruption of tissue processes, possibly metabolic, changes in angiogenesis are reduced with increasing hypoxia, which may in the long run provoke atypical disorders.

Cadmium (Cd) is highly toxic heavy metal which may cause severe biological effects in vivo and in vitro. In this study, an evaluation of the acute Cd ability to trigger micronuclei (MNi) formation was carried out on 3-monthold male and female Albino Oxford (AO) rats using micronucleus (MN) test. Experimental animals were treated intraperitoneally with three different concentrations of cadmium chloride (CdCl2): 0.5, 1, and 2 mg CdCl2 per kg of body weight. Control animals received equal volume of sterile phosphate buffered saline. The results showed that 2 mg CdCl2 per kg b.w. concentration caused a highly statistically significant (P < 0.001) increase in MNi formation in the bone marrow polychromatic erythrocytes (PCEs), exerting a clear-cut concentration-dependent effect. Lower concentrations of CdCl2 used (0.5 and 1 mg/kg b.w.) also caused MNi formation, but with lower statistical significance. Sex differences in MNi production in bone marrow PCEs after acute exposure to different experimental concentrations of CdCl2 were not observed in our study. Our results indicate the ability of CdCl2 to exerts genotoxic effects in bone marrow of AO rats, and complement previous data on the genotoxicity of this important environmental contaminant, burdening the body from different sources - major being industrial exposure, food and cigarette smoking.

Azoles are the main antifungal drug class. The main mechanism of the azoles action is the intercalation in the sterol biosynthesis regulation. At the same time, the effect of the azole derivates on mammals is antiatherogenic. But there were no publication about connection between azole derivates effect on hyperlipidemia and expression of genes with antiatherogenic effects. In our work we used triton model of hyperlipodemia on rats to analyze the effect of carmizole injection on the expression of the main antiatherogenic genes and their regulators Apo A-I, HDL, LDL. We had four groups of rats: intact control group, triton control group, phenophibrate group and carmizole group. During a seven days we gave a per oral injections of carmizole for the carmizole group, phenophibrate (as a comparison drug) for phenophibrate group and 1% starch solution for triton control group. Liver tissue samples were used for RNA extraction and following RT-PCR (Real Time PCR) with primers for Apo A-I mRNA sequence. We have found, that Apo A-I mRNA level decreased in the triton control group to 17%, but restored up to 89% in the carmizole group. Carmizole derivate drug works like stimulator of Apo A-I gene expression. That increasing of the expression of antiatherogenic protein gene could me the base of the antiatherogenic effect of the carmizole derivate.

Two benzofuran derivatives, chlorpromazine and amiodarone, are known to produce inclusion bodies in human tissues. Prolonged high dose chlorpromazine therapy causes hyperpigmentation of the skin with electron-dense inclusion bodies present in dermal histiocytes and endothelial cells ultrastructurally. The nature of the deposits is not known although a drug-melanin complex has been hypothesized. Amiodarone may also cause cutaneous hyperpigmentation and lamellar lysosomal inclusion bodies have been demonstrated within the cells of multiple organ systems. These lamellar bodies are believed to be the product of an amiodarone-induced phospholipid storage disorder. We performed transmission electron microscopy (TEM) and energy dispersive x-ray microanalysis (EDXA) on tissue samples from patients treated with these drugs, attempting to detect the sulfur atom of chlorpromazine and the iodine atom of amiodarone within their respective inclusion bodies.A skin biopsy from a patient with hyperpigmentation due to prolonged chlorpromazine therapy was fixed in 4% glutaraldehyde and processed without osmium tetroxide or en bloc uranyl acetate for Epon embedding.

Apoptotic Genes

Apoptosis is a crucial process in spermatogenesis, responsible for the elimination of abnormal sperm cells and testicular regression out of breeding season. The aim of this study was to assess if the expression of apoptosis-related genes in testicular tissue of domestic cats differed: (1) between normozoospermic and teratozoospermic donors, and (2) between reproductive and non-reproductive season. The expression of genes: BCL2L1, BCL2, BAX, BAD, FAS, FASLG, and caspases (CASP3, CASP8, CASP9, and CASP10) was analyzed by qRT-PCR in testicular tissue samples. During non-reproductive season significantly higher expression of two anti-apoptotic genes (BCL2L1 and BCL2) was observed. Additionally, there was a significant higher expression of CASP10 in teratozoospermic cats during non-reproductive than during reproductive season. No differences were noted between normozoospermic and teratozoospermic groups. Upregulation of some genes during the non-reproductive season indicates engagement of apoptotic mechanisms in the seasonal changes of semen quality in cats, however further studies on protein levels and analysis of changes on distinct testicular germinal layers are required. At the same time, teratozoospermia in the general population of cats seems to be not connected with dysregulation of apoptosis in the testes.

The aim of the analysis was for the first time to assess the expression of genes encoding IL-21 and IL-22 at the mRNA level in ovarian tumor specimens and the concentration of these parameters in serum and peritoneal fluid in patients with ovarian serous cancer. The levels of IL-21 and IL-22 transcripts were evaluated with the use of the real-time RT-qPCR. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration of proteins. Quantitative analysis of IL-21 gene mRNA in the tumor tissue showed the highest activity in the G1 degree of histopathological differentiation and was higher in G1 compared to the control group. The concentration of IL-21 and IL-22 in the serum and in the peritoneal fluid of women with ovarian cancer varied depending on the degree of histopathological differentiation of the cancer and showed statistical variability compared to controls. The conducted studies have shown that the local and systemic changes in the immune system involving IL-21 and IL-22 indicate the participation of these parameters in the pathogenesis of ovarian cancer, and modulation in the IL-21/IL-22 system may prove useful in the development of new diagnostic and therapeutic strategies used in patients, which require further research.

Adult stem cells (ASCs) are the undifferentiated cells that possess self-renewal and differentiation abilities. They are present in all major organ systems of the body and are uniquely reserved there during development for tissue maintenance during homeostasis, injury, and infection. They do so by promptly modulating the dynamics of proliferation, differentiation, survival, and migration. Any imbalance in these processes may result in regeneration failure or developing cancer. Hence, the dynamics of these various behaviors of ASCs need to always be precisely controlled. Several genetic and epigenetic factors have been demonstrated to be involved in tightly regulating the proliferation, differentiation, and self-renewal of ASCs. Understanding these mechanisms is of great importance, given the role of stem cells in regenerative medicine. Investigations on various animal models have played a significant part in enriching our knowledge and giving In Vivo in-sight into such ASCs regulatory mechanisms. In this review, we have discussed the recent In Vivo studies demonstrating the role of various genetic factors in regulating dynamics of different ASCs viz. intestinal stem cells (ISCs), neural stem cells (NSCs), hematopoietic stem cells (HSCs), and epidermal stem cells (Ep-SCs).
