According to a new study, conducted by the Texas A&M University in College Station, a gene taking part in the regulation of biological clock may also protect from breast cancer.
In the course of study the scientists identified two genes, Bmal1 and Per2, produce a cancer-promoting protein when “jetlagged”. Therefore, this may explain also why people who work night shifts have the higher risk of developing cancer.
Professor Porter, the lead investigator, explains: “Per2 is functioning as a tumor suppressor gene associated with cell identity. Right now, we are investigating how our findings relate to humans. There are studies out there showing a relationship between decreased levels of Per2 and certain types of breast cancer, which are more invasive. So, we believe that there is a direct relationship.”
