ULK1 in autophagy: sugar it up
Autophagy Reports, 2022 Autophagy is a highly conserved cellular degradation and recycling process in mammalian cells, which is comprised of three main types: microautophagy, macroautophagy, and chaperone-mediated autophagy (CMA).

DNA damage and autophagy [PDF]
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 2011 Both exogenous and endogenous agents are a threat to DNA integrity. Exogenous environmental agents such as ultraviolet (UV) and ionizing radiation, genotoxic chemicals and endogenous byproducts of metabolism including reactive oxygen species can cause alterations in DNA structure (DNA damage). Unrepaired DNA damage has been linked to a variety of human

Molecules, 2021 The 5′,8-cyclo-2′-deoxypurines (cdPus) affect the DNA structure. When these bulky structures are a part of clustered DNA lesions (CDL), they affect the repair of the other lesions within the cluster.

DNA damage response signaling pathways and targets for radiotherapy sensitization in cancer
Signal Transduction and Targeted Therapy, 2020 Radiotherapy is one of the most common countermeasures for treating a wide range of tumors. However, the radioresistance of cancer cells is still a major limitation for radiotherapy applications.

DNA damage by mycotoxins [PDF]
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1999 Mycotoxins are toxic fungal metabolites which are structurally diverse, common contaminants of the ingredients of animal feed and human food. To date, mycotoxins with carcinogenic potency in experimental animal models include aflatoxins, sterigmatocystin, ochratoxin, fumonisins, zearalenone, and some Penicillium toxins.

DNA Damage and DNA Damage Response in Chronic Myeloid Leukemia [PDF]
International Journal of Molecular Sciences, 2020 DNA damage and alterations in the DNA damage response (DDR) are critical sources of genetic instability that might be involved in BCR-ABL1 kinase-mediated blastic transformation of chronic myeloid leukemia (CML). Here, increased DNA damage is detected by γH2AX foci analysis in peripheral blood mononuclear cells (PBMCs) of de novo untreated chronic ...
