摘要

Background

Coccinia grandis (CG), a plant used as traditional medicine, possesses antioxidant, anti-inflammatory, and anti-fibrotic activities. Chronic kidney disease (CKD) and renal fibrosis are public health issues, further promoted by monosodium glutamate in high-lipid diets (MH) via oxidative stress and inflammation. CG could potentially alleviate MH-induced CKD by modulating cell signaling. The purpose of this study is to hypothesize that CG, with known anti-inflammatory and antioxidant properties, might counteract MH-induced kidney dysfunction through its putative modulation of the signaling pathway.

Methods and results

Male Wistar rats were administered ethanol extracts of CG leaves (etCGL) with or without MH for 28 days, and their effects on renal homeostasis, inflammation, and fibrosis were assessed. Finally, the major components of the MH and CG were docked to identify a better docking affinity and a stable interaction of the ligand with its receptor, highlighting the therapeutic target specificity. etCGL effectively improved kidney function, prevented oxidative stress, and decreased pro-inflammatory cytokines (TGF-β, collagen) in rats fed with MH. Histology demonstrated restored renal structure and minimal fibrosis in the MH + etCGL-fed group. The renoprotective activities of etCGL with its phytocompounds such as catechin, p-coumaric acid, and naringenin as a composite extract were mediated by inhibiting NF-kB and TGF-β/Smad pathways.

Conclusions

Therefore, it can be concluded that CG, with its active compounds, can be a useful dietary approach in MH-associated CKD. Clinical trials across populations would establish the efficacy of etCGL, and understanding its molecular mechanism will be crucial for elucidating the mechanisms of its protective action.
