Abstract: Peroxisome proliferator activated receptors (PPARs) are ligand activated nuclear transcription factors and one of the members of the non steroidal nuclear receptor superfamily. It can be divided into PPAR alpha, PPAR beta / delta and PPAR gamma three subtypes according to the different of its structure and function. Previous studies showed that PPARs participated in biochemical reactions and the regulation of other important biological activities such as lipogenesis, glucose metabolism, inflammation, insulin sensitivity and so on. Recent researches showed that PPARs also had effect of anti-fibrosis, protecting ischemia-reperfusion injury and inhibiting the growth and differentiation of tumor cells. This article reviewed the recent research progress of PPARs in these liver diseases.
