Cold-resistant mice with "bird" muscles

Male infertility can be transmitted through the maternal line

Transgenic mice, insensitive to cold, use the mechanism of heat production in muscles typical of birds, not mammals.

Bile acids instead of vitamin D

Soy Genistein Prevents prostate cancer metastasis

Derivatives of one of the bile acids activate vitamin D receptors without causing an increase in the level of calcium in the blood.

Anxiety is the source of female longevity

The problem was to obtain phosphors of a very small size, comparable to the thickness of the cell membrane of a living organism. And Kharkiv residents succeeded – they managed to obtain single crystals with a size of only two nanometers, each of which contains only 100 molecules.

New target of anti-cancer therapy: pyruvate kinase PKM2

Scientists have isolated an enzyme that gives cancer cells the ability to consume huge amounts of glucose.

Hypertension vaccine

The enzyme pyruvate kinase has two varieties, but only one of them – PKM2 – provides rapid glucose consumption by cancer cells.

Insulin synthesis can be seen in the eyes

One such molecule is similar in shape to a ring with four spokes, which can individually occupy several different positions (which can be interpreted as binary zeros and ones). 16 molecules also make up a ring, with the 17th "sister" in the center, and together form a molecular machine capable of encoding over 4 billion combinations in the position of its parts.

Embryonic stem Cell Protein Suppresses tumor Growth

The antitumor effect of the microenvironment of embryonic stem cells, mediated by the suppression of Nodal protein expression in aggressive cancer cells, opens up new possibilities in cancer treatment. Perhaps Lefty protein is not the only factor secreted by embryonic cells that suppresses tumor growth.

A new target of anti–cancer therapy is tumor stroma

rotative-tumor factor.

It is unconstructive and insufficient to consider the size of the product as a criterion of belonging (or not belonging) to the scientific and technological discipline, as well as the method of assembling its constituent blocks. And speaking of nanotechnology, it is necessary to clarify every time what exactly they mean. At the same time, there cannot be one answer for all technological applications.

New method of genetic modification of stem cells: 100 times more effective

Less growth means longer life?

The PPARa receptor is found in many tissues, including the liver, heart and intestines. In response to the effects of a number of drugs, it activates certain genes. A similar reaction of the receptor is also observed when exposed to fatty acids and compounds with a similar structure.

microRNAs play an important role in the formation of the heart muscle

The Board of Directors of the Russian Venture Company approved the allocation of a billion rubles from the budget for the so-called "seed stage" of venture investment, when an idea turns into a clear business plan. The Ministry of Economic Development will announce the second competition for the selection of management companies on March 14 – 9 billion rubles will be allocated for it. The results will be announced in June 2008.
