HIF1A and esophageal squamous cell carcinoma: miRs of the hypoxia-induced HIF1-αpathways (miR-138-1-3p, miR-106-5p, and miR-27a-3p) were reportedto be correlated with the stemness, metastasis, and progression ofnasopharyngeal carcinoma, esophageal squamous cell carcinoma, andesophageal cancer.64−66 miR-210 knockout PDAC cells under hypoxic conditionsdisplayed differential expression in the miRs under hypoxia-inducedHIF1-α pathways, which suggested correlations among miR-210,cancer stemness, and metastasis.
