Objective:To investigate the autophagy and inflammatory cytokine expression of adipose tissue in high-fat diet induced obese mice and obesity human. Methods:Sixteen male C57 mice were randomly divided into chow diet(CD
n=6)group and high-fat diet(HFD
n=6)group. Mice epididymal and inguinal adipose tissues were collected. Omental adipose tissue was obtained from lean(n=9)and obese(n=9)subjects undergoing laparoscopic cholecystectomy;the two groups of participants were age-and sex-matched
with available clinical parameters. The m RNA levels of Beclin and ATG1 were determined by RT-PCR. Western blot was used to detect the protein expression levels of LC3 and P62 in adipose tissue of each sample. Results:After 8 weeks
mice in HFD group displayed higher weight than control group. Compared with control group
HFD-induced obese mice displayed significant higher protein levels of LC3 and significant lower level of P62 in adipose tissue. The m RNA levels of Beclin(P=0.029)and ATG1(P=0.039)were significant higher in the obesity human adipose tissue than in the lean group. The protein expression levels of LC3 were also significantly higher in obesity group than in control group(P=0.015). Conclusion:Autophagy could be involved in obesity-related adipose tissue dysfunction.
