HIF1A and gastric cancer: Analysis of RNA sequencing dataset in multi‐omics profiles of gastric cancer cells purified from malignant ascites [58] using GEO2R and rnaseqchef software [59] showed that the mRNA of genes including HIF1α, CCL5, and EMT‐related transcription factor SNAI2 (Slug) were upregulated in ST3G5high cancer cells compared with ST3G5low cancer cells (Fig. S8B,C).
