Expression levels of MIR210HG in ESCC. A Chromosomal localization of the MIR210HG gene. B Expression data for MIR210HG in the GEPIA database. C Expression of MIR210HG in tumor vs. normal tissues in the GSE161533 data set. D Overall survival rate of ESCC patients in TCGA, estimated by Kaplan–Meier. E Overall survival rate of ESCC patients in GSE53624, estimated by Kaplan–Meier. F Heatmap showing the top 20 genes positively correlated with MIR210HG in TCGA-ESCC. G Heatmap showing the top 20 genes positively correlated with MIR210HG in GSE53624. *p < 0.05, **p < 0.01, ***p < 0.001
