WebNov 11, 2016 · Hu et al. found a pathological role for the protein AIM2 in irradiation-induced tissue damage. AIM2 is best known for its role in sensing double-stranded DNA in the cytoplasm and alerting the body to infections. It seems that AIM2 also senses DNA damage caused by radiation and then triggers intestinal epithelial cells and bone marrow cells to … WebThe DNA damage theory of aging posits that aging occurs as a consequence of the accumulation of unrepaired damage to DNA in cell nuclei or mitochondria (Bohr et al., …

WebThe term ‘DNA damage response’ (DDR) refers to a network of intracellular pathways that sense and resolve damaged DNA. If unrepaired, DNA lesions may result in cell death (Roos et al., 2016) but can also be a major source of genomic instability particularly when cell death pathways have been deactivated (Halazonetis et al., 2008).
