Abstract
In the present study, we investigated the hypoglycemic effect of different extracts (i.e. organic and aqueous) derived from the fruits of Hyphaene thebaica (doum) on male streptozotocin-induced diabetic rats. Blood glucose levels as well as the relative gene expression of insulin, TNF-α, and TGF-β were determined in the pancreatic tissue of the experimental animals. Treatment of STZ-induced diabetic rats with aqueous extracts of the plant fruit over 7 weeks significantly reduced the elevated blood glucose and increased the relative expression of insulin, while the relative expression of inflammatory mediators (i.e. TNF-α and TGF-β) was significantly reduced. Histopathological investigation also revealed that the aqueous extract treatment effectively reversed the β-cell necrosis induced by STZ and restored its normal morphology. Furthermore, liquid chromatography high resolution mass spectrometry (LC-HRMS) and in silico chemical investigation of the aqueous extract elucidated its major bioactive phytochemicals (i.e. flavonoids) and putatively determined the pancreatic KATP channel as a target for these bioactive components. In vitro insulin secretion assay revealed that myricetin, luteolin, and apigenin were able to induce insulin secretion by human pancreatic cells (insulin production = 20.9 ± 1.3, 13.74 ± 1.8, and 11.33 ± 1.1 ng mL-1, respectively). Using molecular docking and dynamics simulations, we were able to shed the light on the insulin secretagogue's mode of action through these identified bioactive compounds and to determine the main structural elements required for its bioactivity. This comprehensive investigation of this native fruit will encourage future clinical studies to recommend edible and widely available fruits like doum to be a part of DM treatment plans.
