Hydrogen Sulfide Inhibits L-Type Calcium Currents Depending upon the Protein Sulfhydryl State in Rat Cardiomyocytes
Figure 4
Effects of NaHS on the free sulfhydryl groups of L-type calcium channel in H9C2 cells, and a schematic picture showing L-type calcium channel and the other protein molecules involved in myocardial contraction that might react with H2S with their sulfhydryl groups.
In the NaHS group, the L-type calcium channel containing free sulfhydryl groups/total protein of L-type calcium channel ratio in H9C2 cells decreased obviously, compared with that of the control group. **P<0.01 vs control group.
