Figure 5From: SILAC labeling coupled to shotgun proteomics analysis of membrane proteins of liver stem/hepatocyte allows to candidate the inhibition of TGF-beta pathway as causal to differentiationUpstream regulator analysis of membrane protein changes in differently regulated proteins involved in cell-to-cell signaling and interaction. Transforming growth factor beta 1 and the transcriptional factor Slug were identified with significant predicted activation score respectively of −2,20 and −2,22. Symbols are indicated in the predicted legend.Back to article page
