Abstract: The paper reports the first study of genetic diversity of the domestic yak in the Sayan-Altai region of Russia (Altai and Tuva) and Mongolia (Khuvsgul and Gobi) on the basis of the polymorphism analysis of the mtDNA D-loop hypervariable region. It has been demonstrated that, among all the studied populations, Tuva yaks are characterized by the highest haplotype diversity. Four new haplotypes, A4, A13, D9, and E3, have been described for the first time. The analysis of the contribution of maternal genetic component to the yak intrabreed and interbreed mtDNA diversity revealed two large clades. For the first time, comparative analysis of genetic structure of the Russian yak populations was carried out using 15 microsatellite loci. Low genetic difference between the populations was revealed, which may apparently be accounted for by the specific features of farm breeding, in particular, by animal exchange between the adjacent territories of the Sayan-Altai region.

The gold standard of treatment of NMBC patients is transurethral resection, but its implementation does not always allow the patient to be relieved of the recurrence of the disease. In this regard, patients with a low risk of progression after transurethral resection are administered by intravesical chemotherapy, with high risk (T1G2/3) – using instillation with BCG (Bacillus Calmette–Guerin) vaccine. Searching of NMBC markers for laboratory diagnostics, which would help to determine sensitivity or resistance to the planned type of adjuvant therapy remains an actual problem. The data published mainly in the last 5–7 years about genetic predictors of the response to adjuvant chemotherapy and, to a greater extent, immunotherapy with BCG vaccine, are reviewed in this work. Allele combinations in the genes involved in immune response, xenobiotic biotransformation and other loci that are associated with the response to the adjuvant NMBC therapy in meta-analyzes are systematized. Also, expression profiles of mRNA, microRNA and proteins, as well as panels of methylated loci associated with the effectiveness of chemotherapy and immunotherapy of NMBC are considered. It was demonstrated that the somatic mutations sequencing in the primary tumor and the total mutational load using high-throughput sequencing technologies (NGS) identified a number of potential prognostic markers. Perhaps, the mutational load will be more widely used as a highly informative predictor of immunotherapeutic effect in BC: BCG therapy of NMBC and BC targeted therapy using the inhibitors of immune control points, after the standardization of the analysis. This review is intended to oncologists, geneticists, molecular biologists, urologists, pathologists and other specialists working in the field of molecular genetics in oncological urology.

We investigated populations of the Eastern European L. sericata using chaetotaxy and eight microsatellite loci. Our results strongly indicate that a panmictic population of L. sericata exists in the area studied, possibly with a high rate of intra-population gene flow. Analysis of chaetotaxy also supports the panmictic population hypothesis.
