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