Using protein as energy is a waste. It is a big deal. The structure of the protein that helps cancer cells. When cancer cells proliferate quickly, they need the help of a protein called survivin. This protein is abundant in cancer cells, but is almost non-existent in normal cells. This dependence of cancer cells and survivin protein makes survivin a natural target for making new anti-cancer drugs, but there are still some unsolved mysteries about how to deal with survivin protein.
Survivin proteins are unexpectedly combined in a double-paired form-this discovery is likely to provide a new machine for the design of anti-cancer drugs. Survivin protein belongs to a class of proteins that prevent cells from destroying themselves (ie, apoptosis). This type of protein mainly prevents the cell from committing suicide by inhibiting the action of caspases. No scientist has observed the interaction between survivin protein and apoptotic enzymes. There are other signs that the survivin protein plays a different role-helping to pull the cells apart after the cells divide.
Biochemist Guy Salvesen has mastered the structure of the survivin protein "and has not clarified how it prevents suspicious cells from committing suicide." The fact that these proteins are paired is indeed surprising, and it is almost difficult to find unimportant regions of dimerization. The interface between the two proteins will be a good target for anti-cancer drugs to focus on. It is possible that the amount of protein ingested will be excessive. The amount of protein needed to stay healthy varies from person to person. The average healthy adult male or female requires approximately 0.8 grams of protein per kilogram (2.2 pounds) of body weight. As we age, the efficiency of synthesizing new proteins will decrease, and muscle mass (protein tissue) will shrink, while the fat content will remain the same or even increase. This is why muscles seem to "fat" in old age. Infants, adolescents, women during pregnancy, casualties and athletes may usually need to consume more protein daily.
