TGFA (Transforming Growth Factor Alpha): TGFA is a growth factor that binds to the epidermal growth factor receptor (EGFR), initiating a signalling cascade that promotes cell proliferation and differentiation. It plays a crucial role in the development and repair of epithelial tissues and is involved in cancer development through its ability to stimulate cell growth. Studying TGFA offers insights into tissue regeneration and carcinogenesis, highlighting potential therapeutic targets for cancer and diseases related to epithelial tissue damage and repair.
