C-Myc is a protein that plays a crucial role in cell growth, division, and metabolism. It is a transcription factor, meaning it helps regulate the expression of specific genes. By controlling these genes, C-Myc influences various cellular processes, including the cell cycle and apoptosis (programmed cell death). Abnormal activity of C-Myc is often associated with cancer, as it can lead to uncontrolled cell proliferation. In many tumors, C-Myc is overexpressed, contributing to the aggressive nature of the cancer. Understanding C-Myc is essential for developing targeted therapies in oncology.
