Progress in role of silent information regulator 3 in improving idiopathic pulmonary fibrosis by regulating mitochondrial dysfunction / 中国病理生理杂志

ABSTRACT

Idiopathic pulmonary fibrosis(IPF)is a chronic progressive interstitial lung disease of unknown etiology,with a rapid disease course,poor prognosis,and the absence of effective therapeutic drugs.Mitochondrial dys-function is one of the crucial causes of inducing IPF.Silent information regulator 3(SIRT3)can restore mitochondrial ho-meostasis by inhibiting mitochondrial oxidative stress,repairing mitochondrial DNA damage,and ameliorating abnormal mitochondrial lipid metabolism.This paper summarizes the role and mechanism of SIRT3 in attenuating mitochondrial dys-function based on delineating the relationship between mitochondrial dysfunction and IPF,aiming to provide references for finding effective treatment methods for IPF.
