(A) Radial plot of frequency of different KEGG pathways in the DDR_MKOv4 library. Kyoto Encyclopedia of Genes and Genomes pathway enrichment ratio was analyzed from WebGestalt. All the input genes were shown in the top list with false discovery rate < 0.1. Values in radial plot indicate the enrichment ratio calculated using WebGestalt KEGG. (B-K) Radial plots of KEGG pathway enrichment for indicated agents. Please be aware that since these were negative screens, the higher enrichment ratio indicates that a given KEGG pathway is more likely to be depleted following treatment with these agents. HR, homologous recombination; MMR, mismatch repair; FA, Fanconi anemia; NHEJ, nonhomologous end-joining; BER, base excision repair; NER, nucleotide excision repair. ATMi, ATM inhibitor; ATRi, ATR inhibitor; CHK1i, CHK1 inhibitor; PARPi, PARP inhibitor; PKRi, PKR inhibitor.
