Expression and role of peroxisome proliferator-activated receptor ? and nuclear factor-?B in pulmonary fibrosis / 北京大学学报(医学版)

ABSTRACT

Objective:To evaluate the expression of peroxisome proliferator-activated receptor ?(PPAR?) and nuclear factor-?B(NF-?B) in lungs in patients with pulmonary fibrosis,and to explore their effect on the pathogenesis of pulmonary fibrosis.Methods: Immunohistochemical technology was performed to investigate the PPAR? and NF-?B expression in lung specimens from 16 cases of pulmonary fibrosis and 10 cases of normal controls.Results: The positive score of PPAR?(0.35?0.08) in fibrosis group was lower than that in control group(0.42?0.04,P
