VEGFB and gastric adenocarcinoma: By analyzing a public dataset of 376 STAD patients from TCGA, we found that SALL4 mRNA level was significantly correlated with the transcripts of genes related to angiogenesis, including VEGF-A (R = 0.203, P < 0.001), VEGF-B (R = 0.293, P < 0.001), and VEGF-C (R = 0.153, P = 0.003) (Fig. 1D-F).
