To investigate if LINC00202 and miR-3619-5p are in the same axis to regulate RB cell progression, miR-3619-5p inhibitor, the antisense oligonucleotide of the matured miR-3619-5p, was transfected into the cells stably expressing LINC00202 shRNA. The gene discussed is FAM238C; the disease is retinoblastoma.
