Treatment of Metastatic Renal Cell Carcinoma with Checkpoint Inhibitors in Clinical Practice in the Volga-Ural Region of the Eurasian Continent.

Introduction: Renal cancer ranks 10 in the mortality structure of the Russian Federation. The introduction of checkpoint inhibitors has changed the paradigm of treatment of patients with malignant neoplasms.

Method: Data from clinical trials have shown good progression-free median and median overall survival.

Single nucleotide polymorphism rs527236194 of the cytochrome B gene (MT-CYB) is associated with alterations in sperm parameters.

Background: The mitochondrial genome is substantially susceptible to mutations and has high polymorphism due to structural features, location, and lack of recombinant variability, as its inheritance is strictly maternal. All of these events can be accompanied by the accumulation of mitochondrial single nucleotide polymorphisms (mtSNPs) in the sperm. The aim of this research was to analyze the influence of mutations in the MT-CYB gene on sperm quality.

Novel MicroRNA Binding Site SNPs and the Risk of Clear Cell Renal Cell Carcinoma (ccRCC): A Case-Control Study.

Background: Renal cell carcinoma represents 3% of all adult malignancies. MicroRNAs exhibit specific functions in various biological processes through their interaction with cellular mRNA involved in apoptosis and cell cycle control. Recent studies have reported the potential association of single-nucleotide polymorphisms (SNPs) in miRNA-binding sites of VHL-HIF1α pathway genes with renal cancer development and progression.

MicroRNA-200 family expression analysis in metastatic clear cell renal cell carcinoma patients.

The aim of this study is to analyse the of expression levels of microRNA-200 family members in patients with metastatic clear cell renal cell carcinoma (ccRCC). Analysis of microRNA expression was performed on 23 paired DNA samples extracted from kidney tumour tissue and the surrounding normal renal parenchyma. MicroRna-200c was found to have significantly lower expression (in kidney tumour tissue compared to normal renal parenchyma.

Polygenic Risk Scores for Prediction of Breast Cancer and Breast Cancer Subtypes.

Stratification of women according to their risk of breast cancer based on polygenic risk scores (PRSs) could improve screening and prevention strategies. Our aim was to develop PRSs, optimized for prediction of estrogen receptor (ER)-specific disease, from the largest available genome-wide association dataset and to empirically validate the PRSs in prospective studies. The development dataset comprised 94,075 case subjects and 75,017 control subjects of European ancestry from 69 studies, divided into training and validation sets.

Carrier frequency of GJB2 gene mutations c.35delG, c.235delC and c.167delT among the populations of Eurasia.

Hearing impairment is one of the most common disorders of sensorineural function and the incidence of profound prelingual deafness is about 1 per 1000 at birth. GJB2 gene mutations make the largest contribution to hereditary hearing impairment. The spectrum and prevalence of some GJB2 mutations are known to be dependent on the ethnic origin of the population.
