We previously detected a functionally undefined gene amplified on DMs, Ribosomal L22-like1 (\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    ). The relationship between\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    and cancer progression is unknown. Here,\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    was characterized for its role in ovarian cancer (OC) metastasis and its underlying mechanism was examined. DNA copy number and mRNA expression of\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    in OC cells was analyzed using data obtained from The Cancer Genome Atlas and the Gene Expression Omnibus database. An immunohistochemical analysis of clinical OC specimens was performed and the relationships between expression level and clinicopathological factors were evaluated. Additionally,\n                    <jats:italic>in vivo<\/jats:italic>\n                    and\n                    <jats:italic>in vitro<\/jats:italic>\n                    assays were performed to understand the role of\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    in OC. RPL22L1 expression was higher in OC specimens than in normal tissues, and its expression level was highly positively correlated with invasion and lymph node metastasis (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.05).\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    over-expression significantly enhanced intraperitoneal xenograft tumor development in nude mice and promoted invasion and migration\n                    <jats:italic>in vitro<\/jats:italic>\n                    . Additionally,\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    knockdown remarkably inhibited UACC-1598 cells invasion and migration. Further,\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    over-expression up-regulated the mesenchymal markers vimentin, fibronectin, and \u03b1-SMA, reduced expression of the epithelial markers E-cadherin, \u03b1-catenin, and \u03b2-catenin.\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    inhibition reduced expression of vimentin and N-cadherin. These results suggest that\n                    <jats:italic>RPL22L1<\/jats:italic>\n                    induces epithelial-to-mesenchymal transition (EMT).
