Myc is a family of genes that play a crucial role in cell growth, division, and apoptosis (programmed cell death). These genes produce proteins that help regulate various cellular processes, including metabolism and the cell cycle. When functioning normally, Myc helps maintain healthy cell function. However, mutations or overexpression of Myc can lead to uncontrolled cell growth, contributing to the development of cancers, such as leukemia and lymphoma. Researchers study Myc to better understand its role in cancer biology and to develop targeted therapies that can inhibit its activity in tumor cells.
