Germline mutation in ATR in autosomal- dominant oropharyngeal cancer syndrome. Cancer risks and mortality in heterozygous ATM mutation carriers. Incidence of cancer in 161 families affected by ataxia-telangiectasia. In this paper it is shown, using Atm -knockout mice, that ATM plays a role in the DDR to ionizing radiation. Dual roles of ATM in the cellular response to radiation and in cell growth control. DNA repair/pro-apoptotic dual-role proteins in five major DNA repair pathways: fail-safe protection against carcinogenesis. Here, the authors demonstrated a direct link between nuclear caspase 2 and the apoptosis-triggering nuclease CAD.īernstein, C., Bernstein, H., Payne, C. Caspase-2 cleaves DNA fragmentation factor (DFF45)/inhibitor of caspase-activated DNase (ICAD). Apoptosis and autophagy: regulation of apoptosis by DNA damage signalling - roles of p53, 73 and HIPK2. ATM promotes apoptosis and suppresses tumorigenesis in response to Myc. Having pancreatic cancer with tumoral loss of ATM and normal TP53 protein expression is associated with a poorer prognosis.

Wavelength dependence of oxidative DNA damage induced by UV and visible light. Reactive oxygen and nitrogen species as signaling molecules regulating neutrophil function. DNA damage induced by endogenous aldehydes: current state of knowledge. P., Anestopoulos, I., Franco, R., Panayiotidis, M. In this Review, we describe key decision-making nodes in the complex interplay between cell survival and death following DNA damage.
Understanding the molecular basis of these pathways is important not only for gaining insight into carcinogenesis, but also in promoting successful cancer therapy. Furthermore, they determine the outcome of cancer therapy with genotoxic drugs. The pathways that dictate cell fate are entwined and have key roles in cancer initiation and progression. The decision between cell survival and death following DNA damage rests on factors that are involved in DNA damage recognition, and DNA repair and damage tolerance, as well as on factors involved in the activation of apoptosis, necrosis, autophagy and senescence. Cells respond to DNA damage by activating complex signalling networks that decide cell fate, promoting not only DNA repair and survival but also cell death. DNA is vulnerable to damage resulting from endogenous metabolites, environmental and dietary carcinogens, some anti-inflammatory drugs, and genotoxic cancer therapeutics.
