OncoScan analysis to investigate CNV in breast tumors developed by ATM mutation carriers

ABSTRACT: The ataxia telangiectasia-mutated (ATM) gene is a moderate-risk breast cancer susceptibility gene; germline loss-of-function variants are found in up to 3% of hereditary breast and ovarian cancer (HBOC) families who undergo genetic testing. So far, no clear molecular features of breast tumors occuring in ATM deleterious variant carriers have been described, but identification of an ATM-associated tumors signature may help patients' management. To characterize hallmarks of ATM-associated tumors, absolute copy number variation and loss of heterozygosity profiles were obtained from the OncoScan SNP array.

ATM-knockout on total and phosphorylation proteomes of cortical brain organoids

Project description:ATM (ataxia telangiectasia mutated) kinase is crucial to a wide range of human developmental disorders and adult/pediatric malignancies. Its mutations are causally tied to ataxia telangiectasia, a multi-systemic congenital disorder mainly affecting brain and blood systems. We generated 4 separate ATM-knockout human pluripotent stem cell lines and differentiated them to form 3-dimensional brain cortical brain organoids. Brain cortical organoids are an excellent model of human developing cortex. Using these analyses, we identified ATM-dependent phosphorylation predominantly influences factors in neurogenesis, neuronal differentiation, cell morphogenesis, and microtubule cytoskeleton as well as kinases involved in ATM, BNDF, and WNT signaling, G2/M checkpoint, and p53 regulation. These findings have broad implications about diseases associated with ATM, including ataxia telangiectasia.

ATM-deficient B cell lymphomas

Project description:Ataxia-telangiectasia mutated (ATM) kinase plays a central role in maintaining genomic integrity. In both humans and mice, ATM deficiency is associated with an increased incidence of lymphoid cancers that are primarily T cell in origin. We demonstrate here that when T cells are removed as targets for lymphomagenesis and as mediators of immune surveillance, ATM-deficient mice exclusively develop early onset IgM+ B cell lymphomas that by histology and gene expression profiling resemble the activated B cell-like (ABC) subset of human diffuse large B cell lymphomas (DLBCL). These ATM-deficient B cell tumors show considerable chromosomal instability and a recurrent genomic amplification of a 4.48 Mb region on chromosome 18 that contains Malt1 and is orthologous to a region similarly amplified in human ABC-DLBCL. Further, the amplification of Malt1 in these lymphomas correlates with their dependence on NF-kB, MALT1, and BCR signaling for survival, paralleling human ABC-DLBCL. This study reveals that ATM protects against development of B cell lymphomas that model human ABC-DLBCL and identifies a role for T cells in preventing the emergence of these tumors. We performed gene expression profiling on nine ATMKO.CD3epsilonKO lymphoma cell lines (n=12, 3 technical repeats). We analyzed gene expression of anti-IgM stimulated primary B cells from both ATMKO.CD3epsilonKO (n=7, 5 technical repeats) and ATMWT.CD3epsilonKO mice (n=2), and GC B cells isolated from SRBC-immunized ATMWT mice (n=3, 1 biological repeat and 2 technical repeats). We analyzed gene expression following treatment of two ATMKO.CD3epsilonKO lymphoma cell lines with the BTK inhibitor, PCI-32765, at time points (1, 3, 6, and 24 hours) as compared to time points with vehicle (DMSO) (n=8).
