A new study published in Science Advances concluded that there is a potential role for some bacteria on the skin—protecting against cancer. S epidermidis. a common bacteria on healthy skin, exerts a selective ability to inhibit the growth of some cancers, They said “This unique strain of skin bacteria produces a chemical that kills several types of cancer cells but does not appear to be toxic to normal cells.” The researchers found that S epidermidis strain produces the chemical compound SN-hydroxyaminoporine (6-HAP) s epidermidis on their skin. The mice that did not make 6-HAP had many skin tumors after being exposed to cancer-causing ultraviolet rays but mice with S epidermidis strain producing 6-HAP did not. 6-HAP is a molecule that impairs the creation of DNA , known as DNA synthesis, and prevents the spread of transformed cancer cells as well as the potential to suppress the development of ultraviolet induces skin cancers.
Mice receiving intravenous injections of 6-HAP every 48 hours over a two week period experienced no apparent side effects, but when transplanted with melanoma cells, their tumor size was suppressed by more than 50 percent compared to the control group., They said “There is increasing evidence that the skin microbiome is an important element of human health. In fact, we previously reported that some bacteria on our skin produce antimicrobial peptides that defend against pathogenic bacteria such as Staph aureus.”However, they said further study is needed to determine how 6-HAP is produced, if it can be used for prevention of cancer, or if loss of 8-FAP increases cancer risk.
