Genes are the basic “instruction book” for the cells that make up our bodies, and are made out of DNA. The DNA of a person is more than 99% the same as the DNA of any other unrelated person. But no two people have exactly the same DNA except identical twins. Differences in DNA are called genetic variations. They explain some of the physical differences among people, and partly explain why some people get diseases like cancer, diabetes, asthma, and depression, while others do not. Such diseases may also be affected by factors like diet, exercise, smoking, and pollution in the environment, which makes it hard to figure out which genes affect the diseases.
GWATCH is a web-based genome browser designed to automate analysis, visualization and release of data from genome-wide association studies (GWAS) and whole genome sequence association studies of genetic epidemiological cohorts. For any association study, GWATCH allows cataloging and viewing of significant statistical results of association tests (p-values, odds ratios, hazard ratios and others) for single or multiple variants (SNP, indels, CNV), for single or multiple tests.
Comparative genomics of Mycobacterium tuberculosis clinical strains spread in Russia – is one of the research projects conducted at Theodosius Dobzhansky Center for Genome Bioinformatics. We are studying genomic signatures associated with M. tuberculosis clinical and microbiological features. A Database of M. tuberculosis Genome Variations (GMTV) developed by our team, integrates clinical, epidemiological and microbiological information with genome variations based on whole genome sequencing data. This research is conducted in collaboration with St. Petersburg Research institute of Phthisiopulmonology and St. Petersburg Pasteur Institute, and supported by St. Petersburg State University and Russian Foundation for Basic Research (RFBR) grants.
Follicular Lymphoma (FL) is a slow-growing cancer of the lymphatic system, which affects one in every three thousand individuals. While existing frontline therapies are effective at suppressing FL, it remains an incurable disease with a median survival of 8-10 years. A fifth of the patients develop resistance to the standard treatment within the first two years. Understanding the mechanisms facilitating resistance and identifying early molecular prognostic indicators remains a high priority.
Apomixis is asexual way of plant reproduction through seeds, which could be found in more than 400 plant species representing almost 40 families. It is believed that apomixis evolved independently in several taxa from sexual ancestors. Apomixis could be considered as a developmental variation of sexual reproduction in which some steps are lost, reduced, deregulated or desynchronized (Fig.1). The main features of gametophytic apomixis are:
