Indeed, when we compared the expression of the previous genes and miR 17-5p in the tumours according only to their Ki-67 expression, only miR-17-5p was significantly higher in proliferative (Ki-67 ≥ 2.59) compared with non-proliferative tumours (Ki-67 < 2.59) (p = 0.05). This evidence concerns the gene MKI67 and neoplasm.
