Abstract:

Transforming growth factor-beta (TGF-β) superfamily signaling has been a hot spot in recent years. TGF-β superfamily ligands bind to their receptors which activate SMADs. The SMAD proteins form a complex in the cytoplasm, which enters the nucleus through the nuclear pore complex, regulating the expression of specific genes. TGF-β superfamity signaling has a lot of functions relating to fibrosis, tumorigenesis and immunoregulation. TGF-β superfamily signaling plays a key role in the early development of mice. In this review, the characteristics of TGF-β superfamily signaling pathway are discussed. We focus on how this signaling influences mouse early embryonic development.
