Correlation between gene expression levels of TWIST1, EMT and CIN across human cancers. (A) TWIST1 gene expression (log2 RSEM + 0.01) level within and across cancers of TCGA. Each dot represents a tumor sample and the horizontal red bar indicates the median expression value within that cancer cohort. The cancer type abbreviations are shown below. (B) TWIST1 expression in colorectal cancers (COADREAD) stratified by tumor stages. (C) Heatmap representing the correlation coefficient (and its significance) between TWIST1 expression and (i) EMT, (ii) CIN, (iii) DSB gene expression, (iv) mutation count and (v) copy number alteration (CNA) fraction for all 30 distinct cancers, computed using an iteratively reweighted least-squares approach. Color coding indicates the correlation coefficient, ranging from −1 to +1, where −1 being strong negative correlation (dark blue), 0 for no correlation (white) and +1 strong positive correlation (dark red). Significant correlations (q < 0.01) are marked with an asterisk (*).
