Human skin bacteria – Shield against cancer

Bacteria that have protective action against cancer discovered American scientists. It is a strain of staphylococcus epidermidis, which researchers found to produce a chemical that kills skin neoplasms.

As reported in their journal Science Advances, the researchers, led by Professor Richard Gallo, chair of the Department of Dermatology at the University of California-San Diego Medical School, produce the 6-HAP substance that fights them skin tumors.

According to their findings, experimental animals, exposed to strong ultraviolet radiation, developed many skin tumors, but not what they had on the skin of the specific bacteria that produced this substance. 6-HAP is a molecule that prevents DNA generation and thus “brains” the spread of cancer cells.

“We found a staphylococcus strain common in healthy human skin that has a selective ability to inhibit the growth of some cancers. This unique strain of dermal bacteria produces a chemical that destroys several types of cancer cells but does not appear to be toxic to normal cells, “Gallo said.

The animals treated with 6-HAP intravenously every 48 hours for two weeks did not show toxic side effects, while those with melanoma on their skin tumbled in size by at least 50%.

As the AMP transmits, further studies will be undertaken to understand how 6-HAP is produced, whether it can be harnessed for cancer prevention and whether its loss increases the risk of cancer.

As the researchers have said, the new discovery confirms that the skin microbe plays an important role in the defense of the body, even from cancer.
