Expression level of TOP2A in human neurofibroma and MPNST samples and cell lines.

<p>(<b>A</b>) qRT-PCR was used to determine mRNA levels of <i>TOP2A</i> in paired plexiform neurofibroma (NF, blue, n = 9) and MPNST (red, n = 9) formalin-fixed paraffin-embedded tumor samples, each pair being derived from the same NF1 patient. Asterisk indicates P<0.05. (<b>B</b>) qRT-PCR was used to determine mRNA levels of <i>TOP2A</i> in fresh frozen MPNST (red, n = 11), plexiform neurofibroma (blue, n = 7) and atypical neurofibroma (grey, n = 4). (<b>C</b>) qRT-PCR was used to determine mRNA levels of <i>TOP2A</i> in a cell line panel: Hs53.T neurofibroma cell line (blue) and STS26T, sNF96.2, ST88-14, T265 and 90-8TL MPNST cell lines (red). (<b>D</b>) Western blot displaying TOP2A protein expression in cell line panel and HEK293T. ẞ-actin levels are shown as a loading control.</p>
