Ghrelin Protection against Lipopolysaccharide-Induced Gastric Mucosal Cell Apoptosis Involves Constitutive Nitric Oxide Synthase-Mediated Caspase-3 S-Nitrosylation

Figure 2

Effect of H. pylori LPS on the expression of inducible (NOS-2) and constitutive (cNOS) nitric oxide synthase activities in rat gastric mucosal cells. The cells were treated with the indicated concentrations of the LPS and incubated for 16 h. Values represent the means ± SD of five experiments. ${}_{}{}^{*}P<.05$ compared with that of control (LPS, 0).
