PPARA and cancer: The focus ofthis review is the endothelial cell, but it is important to note that PPARα, β/δ, and γ expression and activity have been demonstratedin a variety of cancers, inflammatory cells [34], and in platelets [37–39].Therefore, any effects of PPAR ligands on the development of cancer may beinfluenced by responses in these nonendothelial cell types as well.
