RASGRF2 and neoplasm: However, in agreement with TCGA cohort findings, RASGRF2 staining was significantly more intense in STAD tissue specimens (score > 5 in 70.8 % (51/72)) (Fig. 6Ac-h) than in adjacent non-tumor tissue specimens (score > 5 in 47.2 % (34/72)) (Fig. 6Aa-b) (P = 0.0051) (Fig. 6B) (Table 1).
