- Abstract: Aim To investigate the protective effect of hesperidin (HES) on cardiorenal damage induced by DOCA/Salt hypertension and the underlying mechanisms. Methods Eighteen male SD rats were randomly divided into normal group (Ctrl), model group (DOCA/Salt), and DOCA/Salt with hesperidin group (DOCA/Salt + HES). HES was administered for four weeks. Blood pressure, serum creatinine and blood urea nitrogen were measured. The pathological changes in heart and kidney were examined by HE, Masson and Sirius red staining. The expression of α-SMA, collagen I and TGF-β were detected by Western blot. The mRNA levels of Nlrp3, TNF-α, IL-1β, IL-6 and NOXs were measured using qRT-PCR. Results Compared with the model group, HES administration significantly attenuated the occurrence of DOCA/Salt hypertension, improved renal function indicators of hypertensive rats, reduced renal and cardiac fibrosis, deduced the expression of α-SMA, collagen I and TGF-β, inhibited the expression of Nlrp3, TNF-α, IL-1β and IL-6, and decreased the expression of NOXs in renal and cardiac tissues. Conclusions HES can delay the occurrence of hypertension and protect against hypertension-induced renal and cardiac tissue damage, which may be related to the reduction of inflammatory reaction and oxidative stress by HES.
