ABSTRACT
AIM:
To explore the effect of hydrogen sulfide on the senescence of human umbilical vein endothe -lial cells (HUVECs) induced by high glucose.METHODS:
Senescence model was established by treating HUVECs with33 mmol/L glucose for 48 h.The parameters were detected to demonstrate the effect of hydrogen sulfide on senescence andthe mechanism involved was also investigated .RESULTS:
In the cells treated with high glucose, the proliferation was attenuatedwith a higher number of senescence -associated β-galactosidase (SA-β-Gal) positive cells, and plasminogen activatorinhibitor 1 (PAI-1) protein expression, malondialdehyde (MDA) production and NF-κB p65 activity were increasedsignificantly, but the expression of superoxide dismutase 1 (SOD1) was decreased.However, the cell number and SOD1expression were increased, and the number of SA-β-Gal positive cells, PAI-1 protein expression, MDA production and theactivity of NF-κB p65 were decreased after sodium hydrosulfide (100 and 200 μmol/L) treatment.CONCLUSION:
Exogenoushydrogen sulfide prevents HUVECs against high glucose -induced senescence by suppressing oxidative stress and NF -κB p65 activity.
