Through a CRISPR-based knock-out screen, we identified the DNA methyltransferase 1-associated protein 1 (DMAP1) as a critical regulator of tumor progression. Functional studies showed that loss of DMAP1 exerts its anti-tumor effects through attenuating tumor cell proliferation and activating T cell-mediated adaptive anti-tumor effects. Mechanistically, loss of DMAP1 causes replication fork retardance, disturbs genome stability, and induces endogenous DNA damage, thereby activating tumor-intrinsic immune signaling and enhancing anti-tumor immune response during cancer cell growth. Clinical data analyses revealed that high DMAP1 expression is associated with reduced immune infiltration, a “cold” tumor microenvironment, and poorer overall survival in lung cancer. These findings significantly advance our knowledge of DMAP1's function in lung cancer development and offer a scientific basis for designing novel treatment approaches.","dates":{"publication":"2026/06/24"},"accession":"GSE304428","cross_references":{"GSM":["GSM9150431","GSM9150430","GSM9150428","GSM9150429","GSM9150426","GSM9150427"],"GPL":["24247"],"GSE":["304428"],"taxon":["Mus musculus"],"PMID":["[41904944]"]}}
