Effects of RSG on PTP1B activity in muscle (a) and liver (b) from control and HFD/STZ rats. The muscle and liver tissue homogenate was assayed in a microtiter plate at 27°C. PTP1B activity was measured using a PTP1B assay kit. Means±s.e.m. of six independent experiments is expressed as relative to normal values, which were set as 100%. **P<0.01 vs RSG-untreated control rats. ¶P<0.05 vs RSG-untreated HFD/STZ rats.
