Base excision repair deficient mice lacking the Aag alkyladenine DNA glycosylase. [PDF]

open access: yes, 1997
3-methyladenine (3MeA) DNA glycosylases remove 3MeAs from alkylated DNA to initiate the base excision repair pathway. Here we report the generation of mice deficient in the 3MeA DNA glycosylase encoded by the Aag (Mpg) gene.

Retinoblastoma makes its mark on imprinting in plants [PDF]

open access: yes, 2008
Genomic imprinting results in the preferential expression of alleles from either the maternal or paternal chromosomes. This epigenetic process occurs in embryonic and extra-embryonic (placental) tissues of mammals, but only in the extra-embryonic ...

A New Family of HEAT-Like Repeat Proteins Lacking a Critical Substrate Recognition Motif Present in Related DNA Glycosylases. [PDF]

open access: yesPLoS ONE, 2015
DNA glycosylases are important repair enzymes that eliminate a diverse array of aberrant nucleobases from the genomes of all organisms. Individual bacterial species often contain multiple paralogs of a particular glycosylase, yet the molecular and ...

Resistance-Guided Mining of Bacterial Genotoxins Defines a Family of DNA Glycosylases

open access: yesmBio, 2022
Unique DNA repair enzymes that provide self-resistance against therapeutically important, genotoxic natural products have been discovered in bacterial biosynthetic gene clusters (BGCs).

Mechanisms of base selection by human single-stranded selective monofunctional uracil-DNA glycosylase [PDF]

open access: yes, 2009
hSMUG1 (human single-stranded selective monofunctional uracil-DNA glyscosylase) is one of three glycosylases encoded within a small region of human chromosome 12. Those three glycosylases, UNG (uracil-DNA glycosylase), TDG (thymine-DNA glyscosylase), and

Repair of Hypoxanthine in DNA Revealed by DNA Glycosylases and Endonucleases From Hyperthermophilic Archaea

open access: yesFrontiers in Microbiology, 2021
Since hyperthermophilic Archaea (HA) thrive in high-temperature environments, which accelerate the rates of deamination of base in DNA, their genomic stability is facing a severe challenge.

MutY-Homolog (MYH) inhibition reduces pancreatic cancer cell growth and increases chemosensitivity [PDF]

open access: yes, 2016
Patients with pancreatic ductal adenocarcinoma (PC) have a poor prognosis due to metastases and chemoresistance. PC is characterized by extensive fibrosis, which creates a hypoxic microenvironment, and leads to increased chemoresistance and intracellular

Rewriting Human History and Empowering Indigenous Communities with Genome Editing Tools. [PDF]

open access: yes, 2020
Appropriate empirical-based evidence and detailed theoretical considerations should be used for evolutionary explanations of phenotypic variation observed in the field of human population genetics (especially Indigenous populations). Investigators within

Protein X of hepatitis B virus: origin and structure similarity with the central domain of DNA glycosylase.

open access: yesPLoS ONE, 2011
Orthohepadnavirus (mammalian hosts) and avihepadnavirus (avian hosts) constitute the family of Hepadnaviridae and differ by their capability and inability for expression of protein X, respectively. Origin and functions of X are unclear.

Mfd Protects Against Oxidative Stress in Bacillus Subtilis Independently of its Canonical Function in DNA Repair [PDF]

open access: yes, 2019
Background: Previous reports showed that mutagenesis in nutrient-limiting conditions is dependent on Mfd in Bacillus subtilis. Mfd initiates one type of transcription-coupled repair (TCR); this type of repair is known to target bulky lesions, like those ...
