Compared to normal tissues, NRP1 mRNA expression was significantly increased in most clinicopathological characteristics of STAD; tumor stage (Stage 2, Stage 3 and Stage 4), race (Caucasian and Asian), gender (male and female), age (41–60, 61–80, and 81–100 years old), and tumor grade (Grade 2) as shown in Figure 2a–f. This evidence concerns the gene NRP1 and gastric adenocarcinoma.
