Effects of curcumin on secretion of adiponectin and interleukin-6 in human adipose tissues: an in vitro study / 中西医结合学报

ABSTRACT

OBJECTIVE: To investigate the effects of different concentrations of curcumin on secretion of adiponectin (APN) and interleukin-6 (IL-6) in human adipose tissues cultivated in vitro. METHODS: Seven male patients with kidney stones were admitted. Abdominal subcutaneous adipose tissue and perirenal adipose tissue were collected from the operating-patients, and were cultivated with different concentrations of curcumin (10 and 100 microg/ml) in vitro. The contents of APN and IL-6 in the culture medium of adipose tissue cells were measured by enzyme-linked immunosorbent assay (ELISA) after they were cultured for 6 and 24 hours. RESULTS: Compared with the blank control group, the content of APN in the adipose tissue culture medium was increased by 100 microg/ml curcumin (P<0.05) after 6-hour culture, and the content of IL-6 was significantly decreased by 100 microg/ml curcumin after 6- and 24-hour culture (P<0.05). CONCLUSION: 100 microg/ml curcumin can increase APN secretion and decrease IL-6 secretion in human adipose tissues cultivated in vitro.
