General description

Mothers Against Decapentaplegic Homolog 4 (SMAD4) is a transcription factor that is involved in TGFβ signalling pathways and acts as a tumor suppressor. SMAD4 is commonly expressed in a variety of cancers, including pancreatic ductal adenocarcinoma (PDA), colorectal carcinoma (CRC), hepatocellular carcinoma (HCC), and gastric carcinomas, as well as non-neoplastic liver, pancreas, and colon. However, a loss of expression has been observed in a subset of PDA, CRC, and gastric carcinomas due to a variety of mutations including nonsense, missense, deletions, and splice site changes. In contrast, SMAD4 is over-expressed in HCC compared to the weak expression that is exhibited in the non-neoplastic liver.

Transforming growth factor-beta (TGF-beta) modulates the growth and function of many cells, including those with malignant transformation. Smad proteins have been identified as major components in the intracellular signaling of TGF-beta family members. To clarify the correlations between clinicopathologic profiles

Loss of DNA sequences from chromosome 18q21 is a major genetic change in colorectal tumorigenesis. Multiple genes have been identified in this area. One of these, DPC4 (deleted in pancreatic cancer 4, also known as SMAD4), is mutated in a

In the normal liver, the transforming growth factor beta (TGF-beta) signaling pathway plays an important role in inhibiting hepatocyte growth. This effect is mediated through Smad4 (or Dpc4), a tumor-suppressor gene that affects gene transcription and controls cell growth. A

Loss of chromosome 18q21 is well documented in colorectal cancer, and it has been suggested that this loss targets the DCC, DPC4/SMAD4, and SMAD2 genes. Recently, the importance of SMAD4, a downstream regulator in the TGF-beta signaling pathway, in colorectal

SMAD4 (DPC4) is a tumour suppressor gene that is dysregulated in various tumour types, particularly pancreaticobiliary and gastrointestinal carcinomas. Corresponding loss of protein expression has been reported in approximately 50% of pancreatic and 25% of colonic adenocarcinomas. In the evaluation
