title = "Prolyl Isomerase Pin1 Suppresses Thermogenic Programs in Adipocytes by Promoting Degradation of Transcriptional Co-activator PRDM16",
abstract = "Non-shivering thermogenesis in adipocytes provides defense against low temperatures and obesity development, but the underlying regulatory mechanism remains to be fully clarified. Based on both markedly increased Pin1 expression in states of excess nutrition and resistance to obesity development in Pin1 null mice, we speculated that adipocyte Pin1 may play a role in thermogenic programs. Adipose-specific Pin1 knockout (adPin1 KO) mice showed enhanced transcription of thermogenic genes and tolerance to hypothermia when exposed to cold. In addition, adPin1 KO mice were resistant to high-fat diet-induced obesity and glucose intolerance. A series of experiments revealed that Pin1 binds to PRDM16 and thereby promotes its degradation through the ubiquitin-proteasome system. Consistent with these results, Pin1 deletion in differentiated adipocytes showed enhancement of thermogenic programs in response to the β3 agonist CL316243 through the upregulation of PRDM16 proteins. These observations indicate that Pin1 is a negative regulator of non-shivering thermogenesis.",
