![]() Genomic instability promotes evolution and heterogeneity of tumors. ![]() Unraveling its mechanistic basis is essential for the design of appropriate therapeutic strategies. In a previous study, we reported an unexpected oncogenic property of p21 WAF1/Cip1, showing that its chronic expression in a p53-deficient environment causes genomic instability by deregulation of the replication licensing machinery. We now demonstrate that p21 WAF1/Cip1 can further fuel genomic instability by suppressing the repair capacity of low- and high-fidelity pathways that deal with nucleotide abnormalities. Consequently, fewer single nucleotide substitutions (SNSs) occur, while formation of highly deleterious DNA double-strand breaks (DSBs) is enhanced, crafting a characteristic mutational signature landscape. Guided by the mutational signatures formed, we find that the DSBs are repaired by Rad52-dependent break-induced replication (BIR) and single-strand annealing (SSA) repair pathways. Conversely, the error-free synthesis-dependent strand annealing (SDSA) repair route is deficient. Surprisingly, Rad52 is activated transcriptionally in an E2F1-dependent manner, rather than post-translationally as is common for DNA repair factor activation. The interface and set of functions in GCK will significantly enhance laboratory productivity and minimize experimental design errors - saving users both time and money. Our results signify the importance of mutational signatures as guides to disclose the repair history leading to genomic instability. The Gene Construction Kit software is available for both Windows and Macintosh users, and files can be shared across platforms allowing for easy collaboration. We unveil how chronic p21 WAF1/Cip1 expression rewires the repair process and identifies Rad52 as a source of genomic instability and a candidate therapeutic target. Genomic instability is a hallmark of cancer that plays an important role in shaping tumor behavior over time. Elucidating the molecular routes that drive this phenomenon is essential for designing proper therapeutic strategies as well as monitoring the natural history of carcinogenesis. Not all genetic alterations are driver events, since each type of cancer bears a large number of passenger mutations. ![]() Dual Index Kit TT Set A 96 rxns PN-1000215. 3' CellPlex Kit Set A 48 rxns PN-1000261.
