A PoleP286R mouse model of endometrial cancer recapitulates high mutational burden and immunotherapy response.
Title: A PoleP286R mouse model of endometrial cancer recapitulates high mutational burden and immunotherapy response.
We engineered a conditional PoleP286R allele. PoleP286R/+ embryonic fibroblasts exhibited a striking mutator phenotype and immortalized more efficiently. PoleP286R/+ mice were born at Mendelian ratios but rapidly developed lethal cancers of diverse lineages, yielding the most cancer-prone monoallelic model described to date, to our knowledge.
Title: Polymerase-mediated ultramutagenesis in mice produces diverse cancers with high mutational load.
Loss of DNA Polymerase epsilon is associated with embryonic lethality and extensive developmental abnormalities, leukopenia, and tumor predisposition.
Title: Polε Instability Drives Replication Stress, Abnormal Development, and Tumorigenesis.
A missense mutation in Rev7 disrupts formation of Polzeta, impairing mouse development and repair of genotoxic agent-induced DNA lesions.
Title: A missense mutation in Rev7 disrupts formation of Polζ, impairing mouse development and repair of genotoxic agent-induced DNA lesions.
Findings distinguish Pol epsilon and delta functions in vivo and reveal tissue-specific requirements for DNA replication fidelity.
Title: DNA polymerase epsilon and delta proofreading suppress discrete mutator and cancer phenotypes in mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
