CRNDE and cancer: Overexpression of CRNDE suppressed the expression of miR-384, and down-regulation of CRNDE increased the expression of miR-384 in PTC cell lines, and enforced expression of miR-384 attenuated the oncogenic effects of CRNDE, suggesting that CRNDE acted as a molecular sponge of miR-384 to promote cancer progression in PTC.
