Peroxisome Proliferator-Activated Receptor Gamma and Regulations by the Ubiquitin-Proteasome System in Pancreatic Cancer
Figure 6
The role of PPARγ in the pathogenesis of fibrosis. PTEN induction by PPARγ inhibits the PI3K/Akt pathway downregulating transcription factor Zf9, an inducer of TGFβ. Resulting decrease of TGFβ signaling leads to a decrease of collagen production. UPS regulates all these pathways (not shown).
