Nitric Oxide Protects L-Type Calcium Channel of Cardiomyocyte during Long-Term Isoproterenol Stimulation in Tail-Suspended Rats

Figure 1

NOSs expression of myocardium in 1-, 2-, and 4-week tail-suspended rats and NOS activity in myocardium of 4-week tail-suspended rats. (a) Representative western blots of eNOS, nNOS, and iNOS. β-actin is an internal control. (b) Ratios of nNOS to β-actin in tail-suspended (SUS) and the synchronous control (CON) rats. (c) Ratios of eNOS to β-actin. (d) Total NOS and nNOS activity in the myocardium of 4-week tail-suspended and control rats. Data are mean ± SEM; hearts. , versus synchronous CON.
