CXCR4 and retinoblastoma: Zhong et al. (2019) investigated that NEAT1 knockdown suppressed cell metastasis, whereas promoted cell apoptosis by associating with miR-204 to inhibit CXC chemokine receptor 4 (CXCR4) expression in RB. In this study, the regulatory mechanism of RB progression by NEAT1 was further explored.
