Figure S2. Targeted gene expression analysis in pediatric glioma cell lines. Levels of TNC and related transcripts were measured via qPCR in pediatric supratentorial highgrade glioma (HGG n = 3) and brainstem glioma (DIPG n = 5) cell lines. a) Expression levels of TNC, Notch 1, Notch 2, MYCN and PDGFRA across cell lines studied. Values are normalized to GAPDH expression levels in each cell line. Y-axis: Relative gene expression to GAPDH. Error bars represent standard error of the mean. b) Correlation between TNC expression each gene of interest across cell lines, as measured by qPCR. Positive correlation was found between TNC and Notch 2, and between TNC and PDGFRA, but did not reach statistical significance. c) Correlation between TNC transcription and genes of interest (Notch 1, Notch 2, MYCN, and PDGFRA) across cell lines, as measured by RNA-Seq. TNC expression positively correlated with Notch2 (R2 = 0.817) and PDGFRA (R2 = 0.820). Each data point represents one glioma cell line. (TIF 101751 kb)
