Abstract:

BACKGROUND: It is well known that long-term aerobic exercise alleviates renal dysfunction in spontaneously hypertensive rats. However, the underlying molecular mechanism remains unclear.
OBJECTIVE: To investigate the effect of long-term aerobic exercise on endogenous formation of hydrogen sulfide in the kidney of spontaneously hypertensive rats.
METHODS: Rat models of long-term aerobic exercise were established and randomly assigned to four groups: Wistar-Kyoto (WKY) rat static group, WKY rat exercise group, spontaneously hypertensive rat static group and spontaneously hypertensive rat exercise group. Moderate-intensity exercise on treadmill was given for 12 weeks. At 24 hours after model establishment, weight was weighted. Blood pressure was detected in the caudal artery. Blood and urine were collected for measuring biochemical indicators related to kidney functions. The degree of glomerular sclerosis was observed. Hydrogen sulfide production activity was detected in the kidney. RT-PCR was used to detect mRNA expression levels of hydrogen sulfide production-related enzymes. Simultaneously, oxidative stress of the kidney was observed. 
RESULTS AND CONCLUSION: (1) Long-term aerobic exercise obviously reduced body mass, systolic blood pressure and diastolic blood pressure, increased glomerular filtration rate and renal blood flow, decreased serum creatinine and urea nitrogen levels, urinary albumin levels, significantly reduced glomerular sclerosis score, increased hydrogen sulfide content in plasma and the rate of hydrogen sulfide formation in renal tissue, up-regulated cystathionine γ-lyase expression, obviously diminished malondialdehyde content in serum and kidney, and remarkably increased the reduced glutathione and oxidized glutathione ratio in spontaneously hypertensive rats. (2) Results indicated that long-term aerobic exercise could increase the generation of endogenous hydrogen sulfide in kidney, lessen oxidative stress in the kidney, and ameliorate renal dysfunction in spontaneously hypertensive rats.
