WebbAlthough cytoplasmic AMP-activated protein kinase (AMPK) has been known as a tumor-suppressor protein, nuclear AMPK is suggested to support clear cell renal cell carcinoma (ccRCC). In addition, pAMPK interacts with TGF-β/SMAD, which is one of the frequently altered pathways in ccRCC. In this study, we investigated the prognostic significance of … Webb1 jan. 2024 · Smad4, also known as deleted in pancreatic cancer locus 4 (DPC4), was initially found as a tumor suppressor candidate gene in human pancreatic carcinoma in 1996[30]. The term “Smad” was a combination of the smagene of Caenorhabditis elegansand the madgene of Drosophila melanogaster[31].
