A reliable trap for circulating cancer cells

The system consists of two chips – the first catches and removes erythrocytes and platelets from the blood sample, and the second catches leukocytes, leaving only cancer cells circulating in the bloodstream in the sample.

The gene for premature aging

Mutations in the ATRX gene, which is necessary for telomere replication, cause cognitive impairment, developmental abnormalities and increase the likelihood of developing brain cancer. Researchers from the University of Western Ontario have uncovered the mechanism of this pathology.

Do transposons contribute to age-related neurodegeneration?

The number of transposons ("jumping genes") and their activity in the brain of fruit flies increases with age and correlates with the severity of neurodegeneration. It remains to find out what is the cause and what is the effect.

Telomere shortening rate and age-related diseases

Variants of the structure of genes that determine the rate of "biological aging" – telomere shortening – are associated with the risk of developing age-related diseases, including several types of cancer, cardiovascular and some other diseases.

Obesity and the seven genes

Mutations in one or two of these genes lead to mild metabolic disorders and the development of mild forms of obesity. Extreme forms of obesity develop in cases where a large number of such mutations are present in the genome.
