EMP1 and retinoblastoma: As a previous study revealed that overexpression of miR-34a in RB cells leads to enhanced chemosensitivity against chemotherapeutics [23] and EMP1 has been shown to be regulated by miR-34a in RB cell lines [24], we analyzed the effect of miR-34a and EMP1 overexpression on Y79 cells’ sensitivity towards the common RB chemotherapeutics etoposide, vincristine and cisplatin.
