WNT1 is a gene that plays a crucial role in the Wnt signaling pathway, which is important for various biological processes, including cell growth, differentiation, and development. This gene produces a protein that helps transmit signals between cells, influencing how they communicate and behave. Mutations in the WNT1 gene can lead to various health issues, including bone density disorders and certain types of cancer. Research on WNT1 continues to enhance our understanding of its functions and potential implications in medical science, particularly in regenerative medicine and cancer therapy.
