a, Enrichment plots of genes that are more accessible in MN vs. PN of 4T1 cells against genes that are more accessible in in either long-term reversine-treated or DMSO-treated p53 KO RPE-1 cells. b, Enrichment plots of genes that are more accessible in ruptured MN vs. PN of 4T1 cells against genes that are more accessible in either long-term reversine-treated p53 KO RPE-1 cells or reversine-treated p53 KO RPE-1 cells overexpressing lamin B2. c, Principal component analysis (PCA) plot of TP53 KO hTERT-RPE-1 cells based on a list of tumor suppressor genes and oncogenes, n = 3 biological triplicates. d, KEGG pathway analysis from KEGG Pathways in cancer – Homo sapiens (human) database (map05200). Long-term reversine-treated vs. DMSO-treated p53 KO RPE-1 cells analysis is shown on the left, while long-term reversine-treated lamin B2-overexpressing p53 KO RPE-1 cells vs. long-term reversine-treated p53 KO RPE-1 cells is shown on the right. e, Violin plots representing intraclonal variance across 10kb segments in each of 14 DLD-1 CEN-SELECT clones. Aut. = autosomes, Y = Y chromosome, 1 = chromosome 1, 16 = chromosome 16. Distribution represents 86,666 calculated values for autosomes, 730 calculated values for Y chromosome. ***** p < 0.0001, two-sided Mann-Whitney test. f, Inter-clonal comparison of fold change of ATAC-seq peaks in autosomes, and the Y chromosomes in 14 DLD-1 single clones isolated from CEN-SELECT system to parental control. Aut. = autosomes, Y = Y chromosome, 1 = chromosome 1, 16 = chromosome 16. Bars represent median, statistical significance tested using two-sided Mann-Whitney test. g, Scatter plot comparing ATAC-seq fold change variance to number of breakends per basepair in the Y-chromosome of the clones of DLD-1 CEN-SELECT system cells. h, Scatter plot comparing ATAC-seq fold change variance in regions with breakends to ATAC-seq fold change variance across all regions in the Y-chromosome of the clones of DLD-1 CEN-SELECT system cells. For g and h, statistical test was done using two-sided Pearson’s rank correlation. No adjustments were made for multiple comparisons. i, Density plot showing the comparison of the log2 fold change of H3K27me3 CUT&RUN reads vs. ATAC-seq reads in a given region between DLD-1 CEN-SELECT clones vs. parental, correlation measured with two-sided Spearman’s rank correlation statistic.
