Application of berberine in preparation of drugs inhibiting adipocyte autophagy

Belonging to the field of medicine preparation, the invention in particular relates to application of berberine in preparation of drugs inhibiting subcutaneous adipose and visceral adipose cell autophagy. The invention takes high fat fed mice as experimental objects to test whether berberine inhibits autophagy of subcutaneous adipose and visceral adipose cells of the mice. Specifically, the process includes: feeding C57BL / 6 mice with high fat for 12 weeks, then dividing the mice into a high fat group and a berberine group, continuing the high fat diet and berberine gavage once a day for 4 weeks, using Western Blot to detect the change of autophagy related protein, and using Real-time PCR to detect the change of the corresponding mRNA level. Results show that: under high fat feeding, subcutaneous and visceral adipose tissue autophagy increases, and berberine could effectively inhibit subcutaneous adipose and visceral adipose autophagy of the high fat fed mice, thus providing the experimental data and theoretical basis for more reasonable application of berberine in treatment of obesity clinically.
