Transcriptome Patterns of - and - Mutated Breast and Ovarian Cancers.

Mutations in the and genes are known risk factors and drivers of breast and ovarian cancers. So far, few studies have been focused on understanding the differences in transcriptome and functional landscapes associated with the disease (breast vs. ovarian cancers), gene ( vs.

Population specific analysis of Yakut exomes.

We studied the genetic diversity of the Yakut population using exome sequencing. We performed comparative analysis of the Yakut population and the populations that are included in the "1000 Genomes" project and we identified the alleles specific to the Yakut population. We showed, that the Yakuts population is a separate cluster between Europeans and East Asians.

[The polymorphism of genes of synthesis and metabolism of estrogens and the risk of breast cancer].

The genetic polymorphism of enzymes of synthesis and metabolism of estrogens can input into predisposition to breast cancer. The purpose of actual study was to analyze the associations of polymorphic loci CYP17/B1rs10556836, CYP1A 1rs1048943, CYP1A2rs762551, CYP19A1rs2470152 and CYP17A1rs743572 with risk of development of breast cancer in Russian residents of the Western-Siberian region of Russia. The rates of alleles and genotypes of the given loci were determined in sampling of women suffering with breast cancer (n = 670 females) and in control group (480 females without oncological diseases).

Associations between SNPs within antioxidant genes and the risk of prostate cancer in the Siberian region of Russia.

In the present study we investigated the association of a number of polymorphic changes in antioxidant system genes (SNPs rs1050450 in the GPX1 gene, rs1695 and rs1138272 in the GSTP1 gene and rs4880 in the MnSOD gene) with the risk of prostate cancer. The association of disease stage and PSA levels with specific genotypes was also analyzed. A study was conducted with the participation of 736 Russian men.

Role of polymorphic variants of MTR gene A2756G and SHMT1 gene C1420T in the development of prostatic cancer in residents of the Western Siberian Region of Russia.

Allelic variants of folate cycle enzyme genes can contribute to predisposition to cancer. The impact of polymorphic loci A2756G of MTR gene and of C1420T of SHMT1 gene for the risk of prostatic cancer was studied in residents of West Siberia. The frequency of alleles of these loci in patients (N=371) and controls (N=285) was determined and the data were statistically processed.
