Expression of p-STAT3 and vascular endothelial growth factor in MNNG-induced precancerous lesions and gastric tumors in rats

Figure 5 Protein expression of p-signal transducer and activator of transcription 3 and vascular endothelial growth factor. A: The protein expression of p-signal transducer and activator of transcription (STAT3) in dysplasia and tumor samples was more obvious than that in the other samples; B: The protein expression of p-STAT3 in dysplasia and tumor samples was significantly higher than that in gastritis and atrophic gastritis samples, but the difference between the dysplasia and tumor samples was not significant. The same results were observed for gastritis and atrophic gastritis samples; C: Consistent results were found for the protein expression of vascular endothelial growth factor in samples (^aP < 0.05 vs normal group; ^cP < 0.05 vs gastritis or atrophic gastritis).
