Peroxisome Proliferator-Activated Receptor ? Agonist and Its Target Nanog Cooperate to Induce Pluripotency.

ABSTRACT: The pharmaceutical compounds that modulate pluripotent stem cell (PSC) identity and function are increasingly adopted to generate qualified PSCs and their derivatives, which have promising potential in regenerative medicine, in pursuit of more accuracy and safety and less cost. Here, we demonstrate the peroxisome proliferator-activated receptor ? (PPAR?) agonist as a novel enhancer of pluripotency acquisition and induced pluripotent stem cell (iPSC) generation. We found that PPAR? agonist, examined and selected Food and Drug Administration (FDA) -approved compound libraries, increase the expression of pluripotency-associated genes, such as Nanog, Nr5A2, Oct4, and Rex1, during the reprogramming process and facilitate iPSC generation by enhancing their reprogramming efficiency. A reprogramming-promoting effect of PPAR? occurred via the upregulation of Nanog, which is essential for the induction and maintenance of pluripotency. Through bioinformatic analysis, we identified putative peroxisome proliferator responsive elements (PPREs) located within the promoter region of the Nanog gene. We also determined that PPAR? can activate Nanog transcription by specific binding to putative PPREs. Taken together, our findings suggest that PPAR? is an important regulator of PSC pluripotency and reprogramming, and PPAR? agonists can be used to improve PSC technology and regenerative medicine.
