BMX and neuroblastoma: To examine whether MSI2 and BMX are required for PRKCQ‐AS1‐mediated neuroblastoma cell proliferation, we co‐transfected MYCN‐nonamplified NB69 neuroblastoma cells with an empty vector or PRKCQ‐AS1 expression construct, together with control siRNA, MSI2 siRNA‐1, MSI2 siRNA‐2, BMX siRNA‐1 or BMX siRNA‐2.
