Stapf mitigates ER-stress induced by streptozotocin in rats via down-regulation of GRP78 and up-regulation of Nrf2 signaling. Abstract: ETHNOPHARMACOLOGICAL RELEVANCE: Endoplasmic reticulum (ER) stress plays a role in the pathogenesis of diabetes mellitus, contributing to pancreatic dysfunction and insulin resistance. Ameliorating ER stress may be a viable therapeutic approach in the proper management of diabetes mellitus. Cymbopogon citratus (C.citratus) has been used in traditional medicine in the management of diabetes mellitus. Although well known for its anti-diabetic effect, the mechanism underlying this effect remains unclear.AIM OF THE STUDY: This study was designed to investigate the effect of C. citratus methanolic leaves extract on ER stress induced by streptozotocin (STZ) in wistar rats.MATERIALS AND METHODS: STZ (60 mg/kg) was used to induce ER stress in the pancreas of rats. The rats were administered C. citratus methanolic leaves extract via gastric gavage at doses 100, 200 and 400 mg/kg for two weeks while metformin (100 mg/kg) was used as positive control. Fasting blood glucose (FBG), expression of ER-stress related genes (GRP78, CHOP, ATF4, TRB3, PERK, IRE1), antioxidant (Nrf2 and AhR) and pro-inflammatory (TNF-α) genes were determined. Possible compounds responsible for this effect were also predicted through molecular docking.RESULTS: Induction of ER stress using STZ significantly increased FBG while administration of C. citratus methanolic extract restored it to normal control level (p [URL='https://www.greenmedinfo.com/article/c-citratus-mitigate-er-stress-induced-stz-its-down-regulative-effect-grp78-and']read more[/URL] [/QUOTE]
