Detecting bacteria that live on the skin can prevent cancer

Staphylococcus epidermidis bacteria often live on parasites on human skin, can prevent the development of some forms of cancer. That is the latest study published on February 28 in the American Journal of Science Advances.

Staphylococcus epidermidis bacteria.

According to US scientists, this is the only strain of bacteria that produces a chemical called 6-HAP that can kill some types without affecting normal cells.

Scientists tested mice and found that mice without this strain had many malignant cancerous tumors on their skin after being exposed to ultraviolet (UV) rays, while those that did not have ultraviolet (UV) exposure. The mice with aerial bacteria have these tumors.

6-HAP is a molecule that can inhibit the synthesis of DNA molecules and the growth of cancer cells, said lead researcher Richard Gallo, a professor of dermatology at the University of California, 6-HAP. Therefore, it is possible to prevent the development of UV-induced skin cancer tumors.

Rats injected with 6-HAP every 2 days for more than 2 weeks showed no symptoms showing their normal cells were damaged and when they were transplanted melanocytes, the size of the block Cancer tumors have decreased by more than half compared to mice not given the above chemicals.
