Previously, the engulfment and cell motility 3 (ELMO3) protein has been reported to be involved in cell migration and cytoskeletal remodeling. As of yet, nothing is known about the role of ELMO3 in head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to asses ELMO3 expression in postoperatively irradiated HNSCC patients and to evaluate a possible correlation between this expression and patient survival. ⋯ Our data indicate that in the surgically treated and postoperatively irradiated patients tested, ELMO3 expression serves as a predictive marker for reduced survival.

Previously, it has been reported that microRNA-145 (miR-145) is lowly expressed in human cervical cancers and that its putative tumour suppressive role may be attributed to epithelial-mesenchymal transition (EMT) regulation. Here, we aimed to assess whether miR-145 may affect EMT-associated markers/genes and suppress cervical cancer growth and motility, and to provide a mechanistic basis for these phenomena. ⋯ Our data indicate that low miR-145 expression levels in conjunction with elevated SIP1 expression levels may contribute to cervical cancer development. MiR-145-mediated regulation of SIP1 provides a novel mechanistic basis for its tumour suppressive mode of action in human cervical cancer cells.
