WebbThe recently described family of Smad molecules are essential mediators of transforming growth factor beta (TGF-beta) signalling. To date, seven members of this family have … WebbSmad4 mutations have been reported in HCC. Smad4 at the genetic level is associated with loss of mRNA transcripts and subsequent loss of protein expression. Smad4 protein overexpression is present in a subset of HCC and is strongly correlated with immunostaining of the transforming growth factor beta (TGF-β).

Webb6 dec. 2016 · SMAD4 is a tumor suppressor that is frequently inactivated in many types of cancer. The role of abnormal expression of SMAD4 has been reported in developmental processes and the progression of various human cancers. The expression level of SMAD4 has been related to the survival rate in gastric cancer patients. WebbInterestingly, mutations which eliminate the Smad DNA binding site do not interfere with either TGF-β-dependent transcriptional activation or activation by Smad3/Smad4 cooverexpression.
