Fig 5: Proteogenomic features associated with LIG1.
Heatmap showing copy number, mRNA and protein levels of LIG1, which are significantly (Wilcoxon rank sum test) lower (blue) in non-pCR tumors. Corresponding boxplots show that tumors with low level copy loss of LIG1 (GISTIC = −1, likely single copy number loss) display significantly higher chromosomal instability and multi-gene proliferation scores and significantly lower Signature 3 (COSMIC mutational signature associated with homologous recombination defect) than tumors that that are WT for or show gain of CNA (GISTIC >= 0). T-tests and wilcoxon rank sum tests were used to compare LIG1 loss cases to LIG1 intact (WT/Gain) cases.
