Webb12 apr. 2024 · Thymine glycol (Tg), another type of oxidatively damaged thymine, blocks DNA replication due to its non-planar structure [ 9, 10 ]. 5-Hydroxycytosine (5-ohC), oxidized cytosine, causes a mutation by pairing with adenine and guanine [ 11, 12 ]. Base excision repair (BER) is an important mechanism that removes damaged bases from DNA [ 13 ]. WebbNTHL1 in these extracts was able to excise thymine glycol from both naked DNA and sites in nucleosomes that earlier studies had shown to be sterically accessible. However, the …
Webb5 aug. 2014 · It was initially shown that MSH2-deficient cells had more oxidative damage (8-oxoG and thymine glycol) when exposed to low-levels of ionising radiation [ 42 ]. A subsequent study by Colussi et al. showed that baseline 8-oxoG levels were higher in DNA extracted from MSH2 and MLH1 deficient cell lines [ 41 ]. WebbAdenine (A) and thymine (T) and cytosine (C) and guanine (G) are the bases that makeup DNA (G). A double helix is a spiral shape made up of two long strands of nucleotides. The sugar and phosphate molecules serve as the ladder’s handrails, while the base pair units serve as their rungs.
Webb14 apr. 2024 · It is linked to all important cellular activities and oxidative stress is a result of imbalance between pro-oxidants and antioxidant species. Oxidative stress perturbs many cellular activities, including processes that maintain the integrity of DNA. Nucleic acids are highly reactive and therefore particularly susceptible to damage.
