Researchers have made a groundbreaking discovery that challenges scientists' understanding of programmed cell death and its role in tumour formation. The study found that the body's natural cell-suicide program can fuel tumour development under certain conditions.
Researchers discovered a new biological pathway where microRNA helps protect red blood cells from injury caused by chemicals called free radicals. The study found that the microRNA regulates gene activity by acting on an unexpected signaling pathway, which may have medical implications beyond blood cell development.
Researchers at UT Southwestern Medical Center discovered a tiny RNA fragment, miR-451, that regulates red blood cell production. By inhibiting this process, they hope to develop new treatments for cancers and anemia.
