TLDR
Evidence suggests that ATM-mediated phosphorylation has a role in the response to other types of genotoxic stress and it has become apparent that ATM is active in other cell signalling pathways involved in maintaining cellular homeostasis.
Abstract
The protein kinase ataxia-telangiectasia mutated (ATM) is best known for its role as an apical activator of the DNA damage response in the face of DNA double-strand breaks (DSBs). Following induction of DSBs, ATM mobilizes one of the most extensive signalling networks that responds to specific stimuli and modifies directly or indirectly a broad range of targets. Although most ATM research has focused on this function, evidence suggests that ATM-mediated phosphorylation has a role in the response to other types of genotoxic stress. Moreover, it has become apparent that ATM is active in other cell signalling pathways involved in maintaining cellular homeostasis.

Senescent cells: an emerging target for diseases of ageing.

TL;DR: Therapeutic strategies that safely interfere with the detrimental effects of cellular senescence, such as the selective elimination of senescent cells (SNCs) or the disruption of the SNC secretome, are gaining significant attention, with several programmes now nearing human clinical studies.

ATM and ATR as therapeutic targets in cancer.

TL;DR: Preclinical data have provided a strong rationale for clinical testing of these compounds both in combination with radio- or chemotherapy, and in synthetic lethal approaches to treat tumours with deficiencies in certain DDR components, suggesting that a synthetic lethal approach with ATM or ATR inhibitors could have widespread utility, providing that appropriate biomarkers are developed.

mTOR Signaling in Growth Control and Disease

TL;DR: The mechanistic target of rapamycin (mTOR) signaling pathway senses and integrates a variety of environmental cues to regulate organismal growth and homeostasis as mentioned in this paper, and is implicated in an increasing number of pathological conditions, including cancer, obesity, type 2 diabetes, and neurodegeneration.

DNA damage activates ATM through intermolecular autophosphorylation and dimer dissociation

TL;DR: It is shown that ATM is held inactive in unirradiated cells as a dimer or higher-order multimer, with the kinase domain bound to a region surrounding serine 1981 that is contained within the previously described ‘FAT’ domain.

Reactive oxygen species (ROS) homeostasis and redox regulation in cellular signaling

TL;DR: This review focuses on the molecular mechanisms through which ROS directly interact with critical signaling molecules to initiate signaling in a broad variety of cellular processes, such as proliferation and survival, ROS homeostasis and antioxidant gene regulation, mitochondrial oxidative stress, apoptosis, and aging.
