Effect of PTP1B inhibitors and taurine on blood lipid profiles in adolescent obesity.
The purpose of this study was to investigate the effect of protein tyrosine phosphatase 1B (PTP1B) inhibitors and taurine on blood lipid profiles of the obese adolescent. Three week-old thirty-six male Sprague-Dawley rats were randomly assigned to six groups (high fat diet (HFD) group, HFD group; high fat diet + taurine group, HFD + taurine (TR) group; high fat diet + PTP1B inhibitor A (A) group, HF + A group; high fat diet + PTP1B inhibitor B, HF + B group; high fat diet + PTP1B inhibitor A + taurine group, HF + A + TR group; and high fat diet + PTP1B inhibitor B + taurine group, HF+B+TR group). The body weight of the HF+A and HF + A + TR groups were significantly reduced compared to those of the other groups, the exception being the HF + B + TR group. Serum triglyceride (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels of the HF + A + TR group were significantly reduced compared to those of the other groups. However, serum high density lipoprotein cholesterol (HDL-C) levels in HF + B + TR group was significantly reduced compared those of the HFD and HF + TR groups. Therefore, these results suggest a possible effect of PTP1B inhibitors and taurine on blood triglyceride, total cholesterol and low density lipoprotein cholesterol in the obese adolescent.
