Ribosome biogenesis regulatory protein homolog (RRS1) is a protein required for ribosome biogenesis. Recent studies have identified an oncogenic role of RRS1 in some cancers, whereas the involvement of RRS1 in retinoblastoma (RB) remains to be determined. In this study, we aimed to explore the role of RRS1 in RB. We found that the expression of RRS1 was increased in RB tissues and cells. Lentivirus-mediated RRS1 overexpression promoted the proliferation, growth, and invasion of RB cells. Opposite results were found in RRS1 knockdown cells. In addition, RRS1 silencing induced cell cycle arrest at the G1 phase and apoptosis in RB cells, while RRS1 ectopic expression exhibited the opposite effect. At the molecular level, RRS1 activated the AKT/mTOR signaling pathway, inhibition of which largely blunted the proliferation, growth, and invasion of RB cells. Our study suggests that RRS1 functions as an oncogene in RB through activating the AKT/mTOR signaling pathway.
