Abstract
Quercetin is a naturally occurring phenolic compound abundantly present in plants as a secondary metabolite. The purpose of this study was to investigate the effect of quercetin on improving RINm5F β-insulinemia cell viability, glucose-stimulated insulin secretion (GSIS), and cell insulin content in the presence or absence of streptozotocin (STZ).
This experimental study was conducted on RINm5F β-insulinemia cell line. The cell viability was evaluated by MTT assay. The necrosis was confirmed by flowcytometry and insulin ELISA kit was used to measure the GSIS level and cell insulin content. It should be noted that for testing of cells by 50μM of quercetin, simultaneous treatment and pre-treatment of quercetin were performed in the presence of STZ (20mM).
The quercetin was able to improve the viability of RINm5F cells in the presence of STZ and to increase the GSIS level and cell insulin content under STZ and glucotoxic conditions
The quercetin seems to have beneficial effects on β-cells, especially the synthesis and secretion of insulin. In addition to the therapeutic effect, given the low toxicity of this flavonoid and the results of this study, the quercetin as a preventive agent may play an important role in maintaining the health of β-cells in people at risk of diabetes.
