The gene parasite is trimerized to attack human DNA

Molecular biologists have found out how one of the most successful human parasites lives. It occupied 10% of the DNA in humans and higher primates. According to the authors of the work, they would like to learn his methods of genetic engineering.

Genome: The Autobiography of a Species in 23 chapters

The 23 chapters of the book are 23 human chromosomes. On each one, the author finds some particularly remarkable gene and, starting from it, tells about the origin of life on Earth, about where the soul "hides", about how heredity affects a person's character and abilities, about who is to blame for the fact that a person loses immunity from stress, about where do hereditary diseases and cancer come from…

Genes of cute bullies

The feelings that a person evokes in others depend on his genes – at least, on one of the genes involved in the work of serotonin.

Genetic aspects of skin diseases

Hereditary skin diseases have evolved in recent years from a secondary topic to an important focus of basic and clinical research. There is no doubt that genetics has an important role in solving the pathogenesis of many common skin diseases with a family predisposition, as well as in the development of new ways to treat these diseases.

Fingerprinting of love

Genetic fingerprinting is used both in criminology and medicine, but the greatest flow of examinations for biological kinship still concerns purely domestic problems related to inheritance, alimony and other material benefits.

HIV resistance: one lucky person out of 100

About one percent of the inhabitants of the Old World are immune to the immunodeficiency virus due to a genetic mutation. There are other useful mutations that allow even with HIV infection to postpone the development of the disease for many years.

A database of gene passports is being created in Russia

The State Duma has legalized the introduction of state genomic registration in the country. The Interior Ministry believes that this will increase the effectiveness of the fight against crime.

The color genome is cheap and fast

The complete genomes of two more people have been deciphered: a Nigerian and a Chinese. A detailed analysis of the first "color" genomes is still ahead, but the speed and cheapness of decoding already promise the imminent advent of the era of personal genomics. What this era will look like is unclear.

DNA genealogy: Slavs and "Indo-Europeans" (Part 2)

We have sorted out the ancestral homeland of the "Indo-Europeans", who turned out to be Arias, they are also Proto-Slavs. And where is the ancestral home of the "Proto-Indo-Europeans"? What is the picture of the flows, migrations of "Proto-Indo-Europeans" that led to the appearance of the Aryans, the Proto-Slavs in their historical homeland? This is the second part of our investigation.

DNA genealogy: Slavs and "Indo-Europeans" (Part 1)

Haplogroups and haplotypes do not determine the shape of the skull or nose, hair color, physical or mental characteristics of a person in any way. But they forever bind the carrier of the haplotype to a certain human race, at the beginning of which there was a patriarch of the family, whose offspring survived and lives today, unlike millions of other broken genealogical lines.

How to draw genes

At the current stage of development of functional genomics, it has become possible to determine which genes are expressed in different parts of the body — "work" and which "sleep". And not just to determine, but to obtain three—dimensional images of the distribution of gene activity in all organs and tissues - to create so-called atlases of gene expression.

IV Biologie Prospective Conference "Functional Genomics for Personalized Medicine"

The Eternal Youth Foundation was represented at the conference by the author of this article, who made a poster presentation "Analysis of gene polymorphisms by pharmacy biochip in newborn and elderly people from the North-West region of Russia".

Diseases have matured during evolution

Gene diseases are an unavoidable property of all living things. Most of the genetic diseases are associated with genes inherited from the most primitive organisms. Billions of years of evolution have not made individual genes or their functions more resistant to mutations.

Dr. Watson's visit

The legendary James Dewey Watson, the one who, together with Francis Crick, proposed a model of the DNA molecule in the form of a double helix, came to Moscow at the invitation of the Russian Academy of Sciences, and his lecture at the House of Scientists on Prechistenka was organized by the Dynasty Foundation.

What secrets of longevity do studies on model objects tell about (continued-2)

The role of Sirtuin family genes as potential longevity genes extends to mammals as well.

What secrets of longevity do studies on model objects tell about (continued)

Studies on model objects have revealed a whole family of genes that affect the lifespan of various organisms.

What secrets of longevity do studies on model objects tell about

To date, significant progress in the study of aging genetics has been achieved thanks to work on various model objects.

The genetic component of life expectancy

Genetic regulation of individual development (ontogenesis) is associated with the sequential implementation of various genetic programs in time, ending with the death of an individual.

Viruses have regulated humans

A complex system of regulation of the body at the DNA level, a person may be obliged to retroviruses – distant relatives of HIV. It seems that they gave the "emperor gene" of primates, which controls gene expression in monkeys and humans, its current status.
