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). Here, HIF1A is linked to cancer.
