Downregulation of MANCR inhibits cancer cell proliferation in mantle cell lymphoma possibly by interacting with RUNX2.

In this study, we therefore studied the role of MANCR in mantle cell lymphoma (MCL). We found that serum MANCR and Runt-related transcription factor 2 (RUNX2) were upregulated in MCL patients when compared with those in healthy controls. A positive correlation between serum MANCR and RUNX2 was found in MCL patients but not in controls. Upregulation of serum MANCR distinguished MCL patients from controls. MANCR overexpression promoted RUNX2 expression in MCL cells, while RUNX2 overexpression failed to significantly change the expression levels of MANCR. MANCR overexpression promoted the proliferation of MCL cells, while MANCR silencing inhibited the proliferation of MCL cells. In addition, RUNX2 overexpression attenuated the inhibitory effects of MANCR silencing on cell proliferation. However, MANCR overexpression and silencing had no significant effects on cell migration and invasion. Further bioinformatics analysis showed that MANCR may sponge miR-218 to upregulate RUNX2. Therefore, we conclude that downregulation of MANCR may inhibit cancer cell proliferation in MCL possibly by interacting with RUNX2. PMID: 31650163 [PubMed - as supplied by publisher]
