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.
13.03.2008Embryonic 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.
13.03.2008Electronic health card
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.
12.03.2008Less 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.
12.03.2008microRNAs 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.

Two types of microRNAs, miR-1 and miR-133, associated with the development of muscle tissue, not only stimulate the formation of heart muscle tissue, but also actively suppress genes whose functioning leads to the differentiation of embryonic stem cells into cells of other types, for example, neurons or osteocytes.
11.03.2008An intermediary between unsaturated fatty acids and the genome has been identified
Many of the genes activated by unsaturated fatty acids are involved in the breakdown of these compounds for energy. Most likely, this mechanism protects the liver from the accumulation of unsaturated fatty acids.

Homozygous mutants of the second generation lived ten times longer than ordinary C.elegans, but they were sterile. Maybe it is possible to somehow compensate for the infertility associated with the age-1 gene and leave only a long life? A number of data points to the fact that it is impossible – at least in one action.
