CCNE2 and renal carcinoma: For example, miR-30d inhibited renal carcinoma cell proliferation via the regulation of cyclin E2 expression post-transcriptionally [35]; miR-30d enhanced the invasion and metastasis abilities of hepatocellular carcinoma cells by targeting Galphai2 [31]; Ectopic expression of miR-30d inhibited proliferation and colony formation of anaplastic thyroid carcinoma cells by inducing G2/M-phase cell-cycle arrest via regulating the Polycomb Protein EZH2 [42].
