DNA Damage by Fasicularin [PDF]
Journal of the American Chemical Society, 2005 Fasicularin is a structurally novel thiocyanate-containing alkaloid isolated from the ascidian Nephteis fasicularis. Early biological experiments suggested that this compound's cytotoxic properties may stem from its ability to damage cellular DNA. Sequence gel analysis reveals that treatment of a 5'-32P-labeled DNA duplex with fasicularin in pH 7.0 ...

DNA damage checkpoint kinases in cancer
Expert Reviews in Molecular Medicine, 2020DNA damage response (DDR) pathway prevents high level endogenous and environmental DNA damage being replicated and passed on to the next generation of cells via an orchestrated and integrated network of cell cycle checkpoint signalling and DNA repair ...

Molecular mechanisms of mammalian DNA repair and the DNA damage checkpoints.
Annual Review of Biochemistry, 2004DNA damage is a relatively common event in the life of a cell and may lead to mutation, cancer, and cellular or organismic death. Damage to DNA induces several cellular responses that enable the cell either to eliminate or cope with the damage or to ...

DNA Methyltransferases and DNA Damage
2022Ever since the discovery of depletion of CG sites in mammalian genomes it has been clear that cytosine DNA methyltransferases (DNMTs) are linked to the rate at which mutations accumulate in DNA. Research in the intervening decades has shown that DNMTs influence mutation rates through the indirect consequences of methylation on the mechanism of mutation

Current Opinion in Cell Biology, 2016
Accurate chromosomal DNA replication is fundamental for optimal cellular function and genome integrity. Replication perturbations activate DNA damage tolerance pathways, which are crucial to complete genome duplication as well as to prevent formation of deleterious double strand breaks.

Critical Reviews in Oncology/Hematology, 2020
Poly(ADP-ribose) polymerase (PARP) is a nuclear enzyme that plays a critical role in the repair of single-strand DNA damage via the base excision repair pathway. PARP inhibitors have substantial single-agent antitumor activity by inducing synthetic lethality.

Photochemistry and Photobiology, 1988
Abstract— The direct photomodification of DNA by ultraviolet light or the photo‐induced addition of exogenous compounds to DNA components results in alterations of DNA structure ranging from subtle to profound. There are two consequences of these conformational changes.

Mechanisms of Ageing and Development, 2004
The hypothesis discussed here is that a major component of aging in metazoans is oxidative damage to nuclear DNA. Such a viewpoint would be consistent with the fact that all of the thus far identified premature aging syndromes in mammals involve mutations in nuclear proteins.

DNA Damage and Polyploidization
2010A growing body of evidence indicates that polyploidization triggers chromosomal instability and contributes to tumorigenesis. DNA damage is increasingly being recognized for its roles in promoting polyploidization. Although elegant mechanisms known as the DNA damage checkpoints are responsible for halting the cell cycle after DNA damage, agents that ...
