Thus, deficiencies in the Mre11-dependent DDR drive proliferation and genome instability patterns in p53-deficient breast cancers and represent an opportunity for therapeutic exploitation. b, representative ampar-epsc and nmdar-epsc traces from cultured hippocampal neurons.

Mre11 complex dysfunction is identified in a subset of human triple-negative breast cancers and is associated with increased sensitivity to DNA-damaging therapy and inhibitors of ataxia telangiectasia and Rad3 related (ATR) and poly (ADP-ribose) polymerase (PARP). a, schematic of nrxn1cbln2glud1 and nrxn3cbln2glud1 signalling pathways. SnapGene Viewer is free software that allows molecular biologists to create, browse, and share richly annotated sequence files. Breast tumorigenesis models engineered to express a hypomorphic Mre11 allele exhibit increased levels of oncogene-induced DNA damage, R-loop accumulation, and chromosomal instability with a characteristic copy number loss phenotype. miR-29c holds potential as a biomarker and in cancer therapeutics. HLA class I (HLA-I) glycoproteins drive immune responses by presenting antigens to cognate CD8 + T cells. Overexpression of miR-29c reduces V(D)J recombination, while its quenching increases the efficiency of recombination.

Using a genetically inducible primary mammary epithelial cell model, we demonstrate that Mre11 suppresses proliferation and DNA damage induced by diverse oncogenic drivers through a p53-independent mechanism. A Haploid Genetic Screen Provides a High-Resolution Map of the HLA-I Antigen Presentation Pathway To identify unknown factors regulating HLA-I antigen presentation, we performed a genome-wide insertional mutagenesis screen in haploid human fibroblast-like HAP1 cells endogenously expressing HLA-I ( Brockmann et al., 2017 Carette et al., 2009 ). report that miR-29c is a negative regulator of RAG1 in B cells of mice and humans. The Mre11-Rad50-Nbs1 complex is a DNA double-strand break sensor that mediates a tumor-suppressive DNA damage response (DDR) in cells undergoing oncogenic stress, yet the mechanisms underlying this effect are poorly understood.
