For instance, miR-106a targeting MCL1 to inhibit cisplatin resistance of A2780 in ovarian cancer cells [14] implies a Type-4 association between miR-106a and ovarian cancer; the feedback loops between miR-124 and TGF-β pathways play an important role in metastasis of non-small cell lung cancer [15]. Here, TGFB1 is linked to ovarian cancer.
