Another study proposed that BDNF antisense RNA (BDNF‐AS) may be a prognostic biomarker of retinoblastoma, as low expression of BDNF‐AS is correlated with advanced clinical staging and shorter overall survival, and overexpression of BDNF‐AS in retinoblastoma cells inhibits cancer cell migration and proliferation [120]. The gene discussed is BDNF; the disease is retinoblastoma.
