Compared to para-carcinoma specimens, the relative expression of HIF1A-AS2 was increased in 69.88% (58 of 83) carcinoma specimens (P < 0.001) by approximately 3.472-fold (Figure 1A and 1B), with the relative expression of miR-30a-5p decreasing in 71.08% (59 of 83) of carcinoma samples (P < 0.01) (Figure 1C and 1D). Here, HIF1A is linked to carcinoma.
