After further research on PPAR, I realized it has major role in tissue repair and controlling inflammation at the same time PPAR oddly increase the 3PIK pathway and represses pTEN, which would seem to increase the inflammatory her2 pathway.

'PPARs are major regulators of lipid, glucose, and amino acid metabolism. Here we have presented some of their less well known functions in tissue protection and repair. A majority of the studies reviewed herein are descriptive, and even the use of specific ligands does not necessarily distinguish between PPAR isotypes or between PPAR-dependent and -independent mechanisms. However, collectively, the studies have improved our understanding of the role of PPARs in healing. Their actions are simultaneously systemic and cellular. Systemic effects are antiinflammatory, antioxidant, and metabolic, such as the normalization of circulating lipids and insulin resistance. During the early postinjury inflammatory phase, lipoxygenases and cyclooxygenases stimulate production of PPAR ligands. Indeed, perhaps the most striking action of PPARs is the control of inflammation, an event first observed 10 years ago (119). Inhibition of the NF-B pathway appears to be central to this process."

"Together, these results suggest that the PPAR and PPAR agonists already used in clinics may be harnessed for angiogenic diseases."
