To date, eS7 (RPS7) silencing increased the migration and invasion capacity of ovarian cancer cells [50]; the downregulation of uL15 (RPL27A) reduced migration and invasion in breast cancer cells [51]; and a higher amount of eL15 (RPL15) promoted metastasis in circulating tumor cells from breast cancer patients [52]. The gene discussed is RPL15; the disease is neoplasm.
