Effect of hydrogen sulfide on the proliferation of rabbit vascular smooth muscle cell under high static pressure
Objective
To observe the effect of exogenous hydrogen sulfide(H2S) on the proliferation of rabbit vascular smooth muscle cell(VSMC) under high static pressure.
Methods
Rabbit thoracic aorta VSMC were isolated and cultured under high static pressure(100mmHg) and divided into control group [cultured with 0.2%fetal bovine serum(FBS) and no NaHS]、10%FBS group(10%FBS and no NaHS) and NaHS group(10%FBS and 50mmol/L NaHS). VSMC proliferation was analyzed with BUDR. CSE, Calmodulin(p-CaM)and CyclinD1 protein levels of VSMC were measured by Western blotting.
Results
Compared with the 10%FBS group, NaHS inhibit the proliferation of rabbit VSMC significantly (0.50±0.03 vs. 0.26±0.03, P<0.05). Compared with control group, CSE protein in the 10%FBS group decreased significantly(1.21±0.10 vs. 0.33±0.04, P<0.05) and p-CaM and CyclinD1 protein increased significantly(0.23±0.04 vs. 0.86±0.04 and 0.22±0.03 vs. 1.19±0.06, P<0.05). Compared with the 10%FBS group, CSE protein in NaHS group increased significantly(0.33±0.04 vs. 1.11±0.11, P<0.05), and the expression of p-CaM and CyclinD1 protein decreased significantly(0.86±0.04 vs. 0.26±0.05 and 1.19±0.06 vs. 0.51±0.03, P<0.05).
Conclusion
Exogenous hydrogen sulfide inhibits the proliferation of VSMC under high static pressure by the CSE/H2S pathway which related to the reduction of the expression of p-CaM and CyclinD1.
