Peroxisome Proliferator-Activated Receptor Gamma and Regulations by the Ubiquitin-Proteasome System in Pancreatic Cancer
Figure 3
The role of PPARγ and the UPS in the regulation of p16/CDK4/Cyclin D/Rb axis. Dysfunction of this axis promotes cell proliferation and carcinogenesis. Cyclin D is a transcriptional repression target of PPARγ and a substrate for ubiquitination leading to degradation by the proteasome.
