Sometimes short telomeres prolong life

Genetically determined shortening of telomeres in cancer patients has a positive effect by suppressing uncontrolled division of malignant cells.

Hidden threat

In the genome of each person there is at least one dangerous (usually recessive, not harmful to its carrier) mutation. But inheritance by offspring of two alleles of a defective gene leads to the development of serious diseases and even intrauterine death.

Genetics suggests, and epigenetics disposes

Epigenetics has become the link between the outside world and genes that scientists have been looking for for so long. She finally put all the dots over the "I" in more than a century of discussion about sociogenetism and biogenetism.

The complete Encyclopedia of oncogenes

A detailed catalog of cancer genes will allow selecting the optimal therapy for each patient, selecting targets for the development of anti-cancer drugs, creating experimental models of animals and cell lines for cancer research, testing new drugs and treatment methods.

A "family tree" has been compiled for prostate cancer

Peculiar genealogical trees compiled by scientists show that most of the oncogenic mutations are common to all secondary tumors in each patient. These shared genetic roots could potentially be the Achilles heel of metastases.

Genomes of Icelanders

Analysis of the genomes of 2,636 Icelanders – the largest collection of genetic information about a single human population – allowed scientists to evaluate certain sections of the genomes of another 100,000 people, that is, almost a third of the entire population of the country.

History on the map

The genetic map of Great Britain was compiled in their study by British scientists. In addition to the usual measurements for the map, longitude and latitude, there is also a third one on this map – time.

How is the "repair" of damaged DNA molecules

How DNA "repairs" itself and how DNA breaks are related to genetic diseases, explained Svetlana Khoronenkova, a doctoral student at the Moscow State University Chemistry Faculty, and Grigory Dianov, who works at Oxford University.

The news about the infidelity gene turned out to be exaggerated

There are many genes, each has several functions, so there can be no "adultery gene" in principle. It can only be a predisposition, the contribution of which is often noticeably lower than the contribution of culture, upbringing and circumstances.

The ARHGAP11B gene makes the brain human

We have become smarter thanks to an enlarged brain, and the brain has grown thanks to several genetic tricks that make brain stem cells divide more actively.

Gender Spectrum (Part 2)

So far, we have talked about the fact that the genotype of a human cell can be either XX or XY, as something taken for granted. In fact, this is not quite true, and violation of this rule generates a whole range of diseases.

Gender Spectrum (Part 1)

Not all people can be definitely divided into men and women. According to some (rather bold) estimates, about one person out of a hundred is born and grows up with certain disorders in the formation of gender.

DNA sketches for criminology

The first case when a portrait based on the reconstruction of the phenotype by DNA was made public in the investigation of a criminal case has not yet put the police on the suspect's trail.

Epigenetics and diseases: a place to step forward

Epigenetics is the key to a real understanding of both diseases and the usual signs of the human body, but identifying and confirming these relationships will take a lot of time.
