Effects of atorvastatin on expressions of peroxisome proliferators-activated receptor gamma and MMP-9 in atherosclerosis rabbits / 吉林大学学报(医学版)

ABSTRACT

Objective To study the effects of atorvastatin on the expressions of peroxisome proliferators-activated receptor gamma(PPAR?)and matrix metalloproteinase-9(MMP-9)in atherosclerosis(AS) tissue.Methods Atherosclerotic rabbit models on aortas were established with the high-cholesterol diet,and animals were divided into control,model and atorvastatin groups(n=8).The expressions of PPAR? and MMP-9 and the effects of atorvastatin on them were observed by means of immunohistochemistry.Results The expression of PPAR? in model group(14.38%?2.58%)was higher than that in control group(7.82%?0.96%)(P
