Of relevance to cancer several cell cycle regulating geneswere found by the screen, some of which have been reported as PPAR targets byothers, such as G1/S-specific cyclin E [60],p19INK4d [61], prostate tumor overexpressedgene, serine protease hepsin [62] and the serine/threoninekinases associated with cell cycle regulation p21-activated kinase 4(PAK4), and homeodomain-interacting protein kinase 4.In addition, the prostate tumor marker kallikrein-3 [63]and several other kallikrein gene family members were detected. This evidence concerns the gene KLK4 and prostate neoplasm.
