Expression of RASGRF2 was significantly up-regulated in most TCGA dataset tumor subtypes (relative to TCGA + GTEx dataset normal tissue), including STAD (P < 0.001) (Fig. 1A-B), and was also significantly up-regulated in TCGA dataset STAD tumor tissue (relative to adjacent non-tumor tissue) (P < 0.001) (Fig. 1C). Here, RASGRF2 is linked to neoplasm.
