MEG3 can affect the proliferation and migration of colorectal cancer cells through regulating miR-376/PRKD1 axis. Am J Transl Res. 2019;11(9):5740-5751 Authors: Wu X, Li J, Ren Y, Zuo Z, Ni S, Cai J Abstract The down-regulation of long non-coding RNA (lncRNA) MEG3 has been observed in various cancers; nonetheless, underlying mechanisms are still unclear. The current research work aims at exploring the roles of MEG3 in the pathogenesis of CRC and the associated mechanism. We observed that MEG3 was significantly down-regulated in both CRC tumor tissue and cell lines; also, the transient over-expression of MEG3 in CRC cell line SW480 and LoVo inhibited the proliferation and the migration and clone formation capability of cells; on the other hand, the knockdown of MEG3 has revealed opposite effects. Eventually, we figured it out that target miR-376 directly targeted both MEG3 and PRDK1 in SW480 and LoVo cells. To conclude, as our findings proved, MEG3 is likely to act as a tumor suppressor in the pathogenesis of CRC by means of the regulation of the miR-376/PRDK1 signal axis, suggesting that MEG3 has the potential to become a novel therapeutic target for the treatment of CRC.
