The WNT signaling pathway is a complex network of proteins that plays a crucial role in regulating cell growth, development, and differentiation. It is particularly important during embryonic development and in maintaining the balance of cell proliferation and death in adult tissues. When WNT proteins bind to their receptors on the cell surface, they activate a series of intracellular events that influence gene expression. This pathway is also involved in various biological processes, including stem cell maintenance and tissue regeneration. Dysregulation of the WNT signaling pathway has been linked to several diseases, including cancer, making it a significant area of research in understanding cellular behavior and potential therapeutic targets.
