In order not to get old, do not think about sweet things :-)

The main source of energy and carbon for heterotrophic organisms is glucose, but its excess is associated with the aging process, and its lack slows it down. Scientists from the University of Montreal have discovered that life expectancy is influenced not by the metabolic processes occurring with glucose in the cell, but by the cell's feeling of its amount outside.

Life extension, starvation and gene expression

Different protocols for limiting the diet of C. elegans prolong the life of this organism through different molecular pathways. Knowledge of the relative effectiveness in the fight against senile diseases and the molecular mechanisms of various types of dietary regimens may help in the future in the development of pharmacological drugs to increase life expectancy.

Don't let the cell grow old – control the quality of proteins!

As a cell ages, the quality control mechanism of its proteins changes. Researchers from the Institute of Pathological Chemistry at the University of Mainz have identified control proteins that at the molecular level regulate both potential cellular protein degradation pathways - proteasomal and lysosomal.

If you fight rhinoviruses, the runny nose will pass in a week

Drugs for the prevention and treatment of rhinovirus infections can be divided into four groups: interferons, blockers of cell receptors binding viruses, inhibitors of viral proteases and drugs binding to the capsid of rhinoviruses. Molecular genetic methods can help to obtain new information that can be used to develop drugs against these pathogens.

The Adventures of Stem Cells in Russia

Today it is already clear that the use of stem cells is one of the main directions of modern medicine. And that the simplest, most affordable and cheapest source of them is umbilical cord blood. In Moscow alone, up to 100 thousand babies are born every year, but the umbilical cord blood, whose cells could save lives, is simply destroyed. And by country?

Vaccine for all diseases

Scientists from the Research Institute named after Ellen Scripps cured mice of two types of tumors at once with one vaccine and an additional injection: melanoma and colon cancer. Moreover, tumor resistance was only a demonstration of a new approach, which, according to the authors, with appropriate modification, will be suitable for HIV, influenza, and any other infections.

Who will get the medicines from the shelf?

According to Evgeny Sverdlov, the project manager for the development of the first domestic gene therapy drug against cancer, the appearance of innovative drugs under the brand "Made in Russia" in the coming years is unlikely. Prototypes of drugs that have already been created in our laboratories, which theoretically could compete with Western developments, are being shelved due to the lack of funds for clinical trials, patenting, licensing, production and promotion of drugs to the market.
