Ataxia Telangiectasia Mutated Protein Loss and Benefit From Oxaliplatin-based Chemotherapy in Colorectal Cancer.
(CIG MEDIA GROUP, LP, 2018-12-01)BACKGROUND: Loss of ataxia telangiectasia mutated (ATM), a key protein regulating DNA repair signaling, has been suggested to increase sensitivity to DNA damaging agents. We conducted a study analyzing the loss of ATM ... -
Atlas of Lobular Breast Cancer Models: Challenges and Strategic Directions.
(MDPI, 2021-10-27)Invasive lobular carcinoma (ILC) accounts for up to 15% of all breast cancer (BC) cases and responds well to endocrine treatment when estrogen receptor α-positive (ER+) yet differs in many biological aspects from other ER+ ... -
Atlas of prostate cancer heritability in European and African-American men pinpoints tissue-specific regulation.
(NATURE PUBLISHING GROUP, 2016-04-07)Although genome-wide association studies have identified over 100 risk loci that explain ∼33% of familial risk for prostate cancer (PrCa), their functional effects on risk remain largely unknown. Here we use genotype data ... -
ATM germline heterozygosity does not play a role in chronic lymphocytic leukemia initiation but influences rapid disease progression through loss of the remaining ATM allele
(2012-01)Ataxia telangiectasia patients, with constitutional bi-allelic ATM mutations, have a marked risk of lymphoid tumors and ATM mutation carriers have a smaller risk of cancer. Sporadic ATM mutations occur in 10-20% of chronic ... -
ATM Localization and Heterochromatin Repair Depend on Direct Interaction of the 53BP1-BRCT2 Domain with γH2AX.
(CELL PRESS, 2015-12-15)53BP1 plays multiple roles in mammalian DNA damage repair, mediating pathway choice and facilitating DNA double-strand break repair in heterochromatin. Although it possesses a C-terminal BRCT2 domain, commonly involved in ... -
ATM mutation rather than BIRC3 deletion and/or mutation predicts reduced survival in 11q-deleted chronic lymphocytic leukemia: data from the UK LRF CLL4 trial
(2014-04)ATM mutation and BIRC3 deletion and/or mutation have independently been shown to have prognostic significance in chronic lymphocytic leukemia. However, the relative clinical importance of these abnormalities in patients ... -
ATMIN Is a Tumor Suppressor Gene in Lung Adenocarcinoma.
(AMER ASSOC CANCER RESEARCH, 2019-10-15)Tumor cells proliferate rapidly and thus are frequently subjected to replication stress and the risk of incomplete duplication of the genome. Fragile sites are replicated late, making them more vulnerable to damage when ... -
ATR Inhibition Potentiates the Radiation-induced Inflammatory Tumor Microenvironment.
(AMER ASSOC CANCER RESEARCH, 2019-06-01)PURPOSE: ATR inhibitors (ATRi) are in early phase clinical trials and have been shown to sensitize to chemotherapy and radiotherapy preclinically. Limited data have been published about the effect of these drugs on the ... -
ATR inhibitors as a synthetic lethal therapy for tumours deficient in ARID1A.
(NATURE PUBLISHING GROUP, 2016-12-13)Identifying genetic biomarkers of synthetic lethal drug sensitivity effects provides one approach to the development of targeted cancer therapies. Mutations in ARID1A represent one of the most common molecular alterations ... -
ATR Is a Therapeutic Target in Synovial Sarcoma.
(AMER ASSOC CANCER RESEARCH, 2017-12-15)Synovial sarcoma (SS) is an aggressive soft-tissue malignancy characterized by expression of SS18-SSX fusions, where treatment options are limited. To identify therapeutically actionable genetic dependencies in SS, we ... -
Attenuating Adaptive VEGF-A and IL8 Signaling Restores Durable Tumor Control in AR Antagonist-Treated Prostate Cancers.
(AMER ASSOC CANCER RESEARCH, 2022-06-03)UNLABELLED: Inhibiting androgen signaling using androgen signaling inhibitors (ASI) remains the primary treatment for castrate-resistant prostate cancer. Acquired resistance to androgen receptor (AR)-targeted therapy ... -
Audit feasibility for geometric distortion in magnetic resonance imaging for radiotherapy.
(ELSEVIER, 2020-07-01)BACKGROUND AND PURPOSE: Magnetic Resonance Imaging (MRI) is increasingly being used in radiotherapy (RT). However, geometric distortions are a known challenge of using MRI in RT. The aim of this study was to demonstrate ... -
Aurora B prevents premature removal of spindle assembly checkpoint proteins from the kinetochore: A key role for Aurora B in mitosis.
(2018-04)Accurate chromosome segregation is dependent on the spindle assembly checkpoint (SAC). In current models, the key direct role of Aurora B in the SAC has been suggested to be to promote rapid kinetochore localisation of ... -

Autoimmunity and Benefit from Trastuzumab Treatment in Breast Cancer: Results from the HERA Trial.
(2019-02)BACKGROUND/AIM:This study sought to determine whether an autoimmune background could identify patients with HER2-positive early breast cancer (EBC) who derive differential benefit from primary adjuvant trastuzumab-based ... -
Autoinhibition Mechanism of the Ubiquitin-Conjugating Enzyme UBE2S by Autoubiquitination.
(CELL PRESS, 2019-08-06)Ubiquitin-conjugating enzymes (E2s) govern key aspects of ubiquitin signaling. Emerging evidence suggests that the activities of E2s are modulated by posttranslational modifications; the structural underpinnings, however, ... -
