Spearman’s rank correlation analysis found that the expression of miR-302a-5p/367-3p and the expression of HMGA2 in endometrial cancer were significantly negatively correlated miR-302a-5p: (r = − 0.4316, P < 0.0001, Additional file 11: Table S8-ii); miR-367-3p: (r = − 0.2700, P = 0.0154, Additional file 12: Table S9-ii). Here, HMGA2 is linked to endometrial cancer.
