BMX and neuroblastoma: By contrast, using the median, low or upper quartile of PRKCQ‐AS1, MSI2 and BMX RNA expression as the cut‐off, Kaplan‐Meier survival analyses showed that high levels of PRKCQ‐AS1, MSI2 or BMX expression in MYCN‐amplified human neuroblastoma tissues did not correlate with poor patient prognosis (Figure S8A–C, Supporting Information).
