TLDR
Evidence and hypotheses about the new pathophysiological aspects of PPARs activation are reviewed and it is shown that both PPARa and PPARg activation reveal cardio-protective effect in hypertension-induced cardiac hypertrophy.Abstract:
Peroxisome proliferator activated receptors (PPARs) belong to a subfamily of transcription nuclear factors. Three isoforms of PPARs have been identified: alpha, beta/delta and gamma, encoded by different genes and distributed in various tissues. They play important roles in metabolic processes like regulation of glucose and lipid redistribution. They also have anti-atherogenic, anti-inflammatory as well as anti-hypertensive functions. In hypertension-induced cardiac hypertrophy, both PPARa and PPARg activation reveal cardio-protective effect. Despite these beneficial functions, several recent experimental reports point to the possibille unfavorable effects of PPARs activation in lipid metabolism (lipotoxicity) in cardiomyocytes, which can lead to pathologic cardiac hypertrophy in such diseases as diabetes type 2, metabolic syndrome or obesity. This paper reviews evidences and hypotheses about the new pathophysiological aspects of PPARs activation.read more

TL;DR: A metabolic function for the promyelocytic leukemia (PML) gene is identified, uncovering an unexpected role for this bona fide tumor suppressor in breast cancer cell survival and its key role in fatty acid oxidation metabolism are amenable to pharmacological suppression, a potential future mode of cancer prevention and treatment.

PPARγ and GLUT-4 expression as developmental regulators/markers for preadipocyte differentiation into an adipocyte
TL;DR: This review provides information as to how differentiation of a cell to become a viable (and new) adipocyte is under different regulation than that experienced by an immature adipocyte that is just beginning to accumulate lipid.
