Which marker is involved in the process of cell growth and proliferation?

• A. p53
• B. APC
• C. BRAF
• D. KRAS

Answer: (C)

The correct answer is BRAF, as this gene encodes a protein that is part of the MAPK/ERK signaling pathway, which plays a vital role in cell growth and proliferation. Mutations in the BRAF gene are known to lead to increased signaling activity, which can promote unchecked cell division and contribute to the development of various cancers, particularly melanoma. BRAF acts as a kinase that activates downstream signaling molecules, enhancing cellular processes related to growth and survival. The dysregulation of this signaling pathway via BRAF mutations is a key mechanism by which cancer cells can escape normal growth control, leading to tumorigenesis. Understanding the role of BRAF in cell proliferation provides insight into targeted therapies that can inhibit its activity and potentially treat cancers associated with its mutation.
