Fig. 4. Mutation patterns for MMR- populations.
a The 96-class contextual mutational spectra for the three mutation patterns (MPs) for the evolved populations with MMR- background or the L10 transfer scheme based on the dimensionality reduction analysis. Each bar represents a class; each class represents a single nucleotide change (one of six colored blocks; labels on the top) with the context of 3′ and 5′ flanking nucleotide (ticks at the bottom). b Three MPs largely contribute to the mutation profiles of clones isolated from the evolved populations with MMR- background or the L10 transfer scheme. c Correlation coefficients between each MP and each of 96-class mutational spectra from various MMR-deficient organisms (G+: Gram-positive bacteria; G-: Gram-negative bacteria). d Correlation coefficients between each MP and each of 96-class spectra for human cancer. SBS6, 14, 15, 20, 21, 26, and 44 are seven MMR-deficient spectra (single base substitutions; SBS) annotated in the human cancer database, COSMIC. For (c, d), the size and colour of circles represent the values of correlation coefficients (r; shown if ≥0.7). Source data are provided as a Source Data file (Data 3).
