Upregulation of MANCR predicts poor survival in patients with gastric cancer

A previous study revealed that MANCR (mitotically associated long non-coding RNA) is implicated in breast cancer. The present study investigated the potential role of MANCR in gastric cancer (GC) and revealed that MANCR was upregulated in GC tissues compared with non-cancerous tissues. MANCR express...

Description
Summary:A previous study revealed that MANCR (mitotically associated long non-coding RNA) is implicated in breast cancer. The present study investigated the potential role of MANCR in gastric cancer (GC) and revealed that MANCR was upregulated in GC tissues compared with non-cancerous tissues. MANCR expression was not affected by clinical stages and a high MANCR expression level was associated with poor survival time. MicroRNA (miR)-101 was downregulated in cancer tissues compared with non-cancerous tissues and was inversely associated with MANCR expression. MANCR overexpression in GC cell lines in vitro resulted in miR-101 downregulation; however, miR-101 overexpression did not alter MANCR expression. Furthermore, MANCR overexpression promoted, while miR-101 overexpression inhibited GC cell proliferation. In addition, miR-101 overexpression decreased the effect of MANCR overexpression. The results obtained in the present study revealed that MANCR expression was associated with the survival of patients with GC, and MANCR overexpression in vitro may promote GC by downregulating miR-101 and increasing the proliferation of GC cells.
