Abstract
DNA mismatch repair (MMR) is an important pathway which helps to maintain genomic stability. Mutations in DNA MMR genes are found to promote cancer initiation and foster tumor progression. Deficiency or inactivation of MMR results in microsatellite instability (MSI) which triggers neoantigen generation and impairs tumor growth. Immunotherapies targeting MMR can increase the burden of neoantigens in tumor cells. While MSI has been regarded as an important predictor of sensitivity and drug resistance for immunotherapy-based strategies. Different approaches targeting genomic instability have been demonstrated to be promising in malignancies derived from different tissues. Underlying MMR deficiency-associated immunogenicity is important for improving the therapeutic efficacy of immunotherapies. In this review we provide an overview of the MMR systems, their role in tumorigenesis, drug resistance, prognostic significance and potential targets for therapeutic treatment in human cancers, especially in hematological malignancies.
