Gestational diabetes mellitus (GDM) is the serious complication of pregnancy induced via dysfunction in glucose metabolism during the pregnancy. Crocetin already proved antidiabetic effect in streptozotocin (STZ)-induced diabetes mellitus in rats. In this protocol, we have investigated the potential effect of crocetin against STZ-induced GDM in rats. Wistar rats were used for the current protocol; STZ was used for the induction for DM and finally caused the GDM. Body weight and serum advanced glycation end products level were estimated at regular time intervals. We also estimated the fetus weight and placental weight. Biochemical, antioxidant, pro-inflammatory cytokines, inflammatory mediators, and apoptosis parameters were estimated. mRNA expression of NOX2, RAGE, MCP-1, VCAM-1, EGFR, and p65 were also estimated. Crocetin treatment significantly (p < .001) reduced the fetus weight and increased the placental weight and index. Crocetin significantly (p < .001) reduced the blood glucose level and increased the body weight. Crocetin significantly (p < .001) boosted the level of antioxidant enzymes and includes superoxide dismutase, glutathione peroxidase, glutathione, and catalase. Crocetin significantly (p < .001) altered the level of lipid parameters and pro-inflammatory cytokines. Crocetin significantly (p < .001) reduced the level of intercellular adhesion molecule 1, cyclooxygenase-2, and nuclear factor kappa B and increased the level of visfatin against GDM rats. Crocetin significantly (p < .001) altered the level of mRNA expression. Based on the result, we can say that crocetin is a protective drug against the GDM in pregnant rats via antioxidant, inflammatory, and apoptosis parameters. PRACTICAL APPLICATIONS: As we all know, gestational diabetes mellitus (GDM) cases rise all over the world. The current investigation showed the protective effect of crocetin on GDM in experimental rats. The current finding exhibited the protective effect of crocetin against STZ-induced GDM via suppression of inflammatory, oxidative, and apoptosis parameters. The result suggests the antioxidant and anti-inflammatory effect of crocetin. Crocetin can be used as a preventive medication in the treatment of gestational diabetes mellitus, according to the latest findings.
