Tropisetron improves pancreas function and increases insulin synthesis and secretion in the STZ-induced diabetic rats: involvement of UCP2/ZnT8 pathway.
Diabetes mellitus is one of the most common metabolic diseases. Tropisetron, as a 5-HT3 receptor antagonist, has a considerable role in the inflammation and oxidative stress lowering. This study aimed to investigate the effect of this 5-HT3 receptor antagonist on insulin secretion in male diabetic rats and the possible mechanisms.. Animals were divided into five equal groups; the control, tropisetron, diabetes, tropisetron-diabetes and glibenclamide-diabetes (7 in each group). Tropisetron and glibenclamide were administrated for 2 weeks after inducing type 1 diabetes.. We demonstrated that insulin secretion improved robustly in diabetes-tropisetron compared with the diabetic group. Oxidative stress biomarkers were lower in a diabetes-tropisetron group than in diabetic rats. Simultaneously, tropisetron administration promoted the expression of ZnT8 and GLUT2 and also beta-cell mass in pancreatic tissue, while the expression of uncoupling protein 2 (UCP2) was restrained. The histological evaluation confirmed our results. These effects were equipotent with glibenclamide, indicating that tropisetron can protect islets from the abnormal insulin secretion and morphological changes induced by type 1 diabetes.. This effect might be partly related to the modulated UCP2/ZnT8 signal pathway and improved oxidative stress-induced damage.

Tropisetron attenuates pancreas apoptosis in the STZ-induced diabetic rats: involvement of SIRT1/NF-κB signaling.
Diabetes mellitus (DM) is one of the most common diseases in the worldwide. Type 1 diabetes mellitus (T1DM) is characterized by insulin deficiency and beta cells apoptosis. Tropisetron as a 5-HT3 receptor antagonist has positive effects on the inflammation, apoptosis and glucose lowering. The aim of this study was to investigate the effect of tropisetron on β-cells apoptosis and its possible pathways.. Animals were divided into five equal groups: the control, tropisetron, diabetes, tropisetron-DM and glibenclamide-DM (seven in each group). Tropisetron and glibenclamide were administrated for 2 weeks after type 1 diabetes induction. Real-time PCR, western blot analysis and TUNEL assay were performed.. We found that tropisetron decreased blood glucose and increased insulin secretion. Protein expression of NF-κB was downregulated, while protein expression of SIRT1 upregulated after tropisetron treatment. Moreover, Bax/Bcl2 ratio decreased in tropisetron-DM group and finally, apoptosis improved in pancreas tissue.. It seems that tropisetron administration improves STZ-induced apoptosis and diabetes in the animals. This effect might be resulted from involvement in NF-κB/ SIRT1 pathway.
