Introduction Acute myeloid leukemia (AML) is characterized by high genomic instability and elevated relapse rates associated with chemoresistance. The ATM–p53 axis regulates the DNA damage response (DDR), controlling genomic repair, cell cycle arrest, and apoptosis in response to chemotherapeutic agents such as cytarabine, cisplatin, and etoposide. Its dysfunction promotes cell survival and clonal evolution. Caenorhabditis elegans emerges as a conserved experimental model for studying DDR and therapeutic resistance. Objective To analyze the role of the ATM–p53 axis in AML chemoresistance and evaluate the utility of C. elegans as a translational model. Method. Narrative review in PubMed, Scopus, and Google Scholar, prioritizing original articles and reviews from the last 15 years on ATM, p53, AML, DDR, chemoresistance, and C. elegans. Results Alterations in ATM and p53 compromise DDR, favoring apoptosis evasion and activation of compensatory repair and survival pathways, contributing to resistance against cytarabine, cisplatin, and etoposide. C. elegans, through the orthologs atm-1 and cep-1, recapitulates DDR processes and chemoresistance observed in human cells. Conclusion ATM–p53 axis dysfunction is a key determinant of chemoresistance in AML. C. elegans represents a robust platform for identifying conserved molecular vulnerabilities and developing new antileukemic therapeutic strategies.
