D-ribose-L-cysteine prevents oxidative stress and cardiometabolic syndrome in high fructose high fat diet fed rats

Abstract

Cardiometabolic syndrome has been linked with dietary modification. Therefore, we investigated the effects of D-ribose-L-cysteine (DRLC) in rats fed with high fructose high fat (HFHF) diet. Twenty rats (n = 5), divided into 4 groups were concurrently exposed to HFHF and/or DRLC (250 mg/kg, p.o) during the 8 weeks study. The result showed that compared to control group, HFHF group had significant impairment in lipid and glucose homeostasis, increased cardiac xanthine oxidase, systolic blood pressure, heart rate, %body weight change and fluid intake. Also, there were significant reductions in HDL-C, cardiac (GPX, NO&GGT), feed intake and relative heart weight in the latter, relative to the former. However, there were no significant differences in most of the observed physical and biochemical changes in HFHF + DRLC group compared to control. DRLC alone did not disrupt the level of biomarkers. Conclusively, DRLC prevented the manifestation of oxidative stress and cardiometabolic syndrome in HFHF-diet fed rats.
