TGF-alpha, or Transforming Growth Factor-alpha, is a protein that plays a crucial role in cell growth and development. It is part of a larger family of growth factors that help regulate various cellular processes, including proliferation, differentiation, and survival. TGF-alpha is particularly important in the context of wound healing and tissue repair. This protein interacts with specific receptors on the surface of cells, triggering signaling pathways that promote cell division and tissue regeneration. Abnormal levels of TGF-alpha have been associated with certain diseases, including cancer, where it can contribute to tumor growth and progression. Understanding TGF-alpha is essential for developing targeted therapies in oncology.
