Effect of CLE on glucose uptake in L6 myocytes. L6 cells were induced to differentiate with 2% horse serum and treated as indicated. Glucose uptake was first measured at different doses (A). Then, glucose uptake was measured at different time intervals (B), using most effective dose (250 μg/mL). Control: fully differentiated L6 cells. 100 nM insulin (IN) was used as the standard drug. Data are presented as the mean ± SD (n = 3). *
p < 0.05 and **
p < 0.01 versus control.
