Figure 1. Effect of UA on the viability of 3T3-L1 adipocytes.

Mature 3T3-L1 adipocytes were incubated with different concentrations of UA for 24, 48, or 72 h, respectively. The MTT reagents were added to the medium. After 4 h of incubation, the medium was aspirated and 150 µL DMSO was added to each well. The absorbance was measured at 570 nm. Data are expressed as means ± SD (n = 3). *P<0.05, **P<0.001 and ***P<0.001 vs. the control of 0 µM UA.
