Abstract
Polystyrene microplastics (PSMP) are toxic environmental contaminants which can damage various body organs including kidneys. Delphinidin (DEL) is a potential anthocyanidin flavonoid with significant pharmacological benefits. This research was conducted to analyze the protective effect of DEL to avert PSMP prompted renal dysfunction. Rats (n = 24) were divided into 4 separate groups: Control, PSMP (0.01 mgkg−1), PSMP (0.01 mgkg−1) + DEL (25 mgkg−1) and only DEL (25 mgkg−1). Our results showed that PSMP exposure reduced the expressions of Nrf-2 and antioxidant genes while increasing the expression of Keap1. Besides, PSMP intoxication escalated the level of kidney injury markers (urea, KIM-1, creatinine and NGAL) while inducing substantial reduction in the levels of creatinine clearance. Moreover, PSMP significantly reduced the levels of GSH, GST, SOD, HO-1, CAT, GSR, GPx while escalating MDA and ROS. Conversely, inflammatory biomarkers including IL-1β, TNF-α, NF-kB, IL-6 and COX-2 activity were increased due to PSMP intoxication. Our results showed that PSMP administration increased the expressions of Bax and caspase-3 while decreasing the expression of Bcl-2. However, DEL treatment significantly restored the PSMP-induced renal impairments. Therefore, it is suggested that DEL could be used as a therapeutic compound to alleviate PSMP-induced kidney damage in rats, possibly due to its strong pharmacological properties.
