Atrial natriuretic peptide signal pathway upregulated in stomach of streptozotocin-induced diabetic mice

Figure 4 RT-PCR of gastric ANP and NPR-A genes in control and STZ-induced diabetic mice. A: Results of agarose gel electrophoresis, including ANP, NPR-A and GAPDH genes. The density signal was normalized to that of GAPDH. The mean value of the density was obtained from three separate experiments; B: Expression of ANP and NPR-A genes was increased in STZ-induced diabetic mice (n = 3; ^aP < 0.05, ^bP < 0.01 vs control).
