This study investigated the clinical significance of <i>miR-372</i> expression in CRC. <i>Methods: </i>qRT-PCR was used to evaluate <i>miR-372</i> in 144 CRC patients, and large tumor suppressor 2 <i>(LATS2)</i> expression was also examined as the likely target gene of <i>miR-372</i>. In vitroassays were performed to evaluate the biological function of<i> miR-372. </i><i>Results: </i>Multivariate analysis indicated that high<i> miR-372</i> expression was an independent prognostic factor (p = 0.006). High <i>miR-372</i> expression was associated with synchronous liver metastasis (p = 0.035). We found an inverse relationship between<i> miR-372 </i>and <i>LATS2 by</i> qRT-PCR (p = 0.007) and immunohistochemistry (p = 0.042) using CRC tissue samples. Furthermore, pre-miR-372 led to a decrease in the LATS2 protein and an increase in proliferative activity of LoVo cells. We also found a significant association between low <i>LATS2</i> expression and liver metastasis (p = 0.042). <i>Conclusions:</i> This study suggested that <i>miR-372</i> was a novel independent prognostic factor in CRC. Our data suggest that <i>LATS2 </i>may serve as one of the target genes of <i>miR-372 </i>in clinical CRC tissues. MicroRNA;Colon cancer;Liver metastasis;Prognosis;LATS2 2012-03-26
