Characterization of a conserved interaction between DNA glycosylase and ParA in Mycobacterium smegmatis and M. tuberculosis. [PDF]
PLoS ONE, 2012 The chromosome partitioning proteins, ParAB, ensure accurate segregation of genetic materials into daughter cells and most bacterial species contain their homologs. However, little is known about the regulation of ParAB proteins.

DNA Nanotechnology Meets Nanophotonics [PDF]
Nano Lett. 20 8430 (2020), 2021 In the past decades, DNA has been intensely studied and exploited in different research areas of nanoscience and nanotechnology. At first glance, DNA-based nanophotonics seems to deviate quite far from the original goal of Nadrian Seeman, the founder of DNA nanotechnology, who hoped to organize biological entities using DNA in high-resolution crystals.

IMG-DNA: Approximate DNA Storage for Images [PDF]
, 2021 Deoxyribonucleic Acid (DNA) as a storage medium with high density and long-term preservation properties can satisfy the requirement of archival storage for rapidly increased digital volume. The read and write processes of DNA storage are error-prone. Images widely used in social media have the properties of fault tolerance which are well fitted to the ...

OGG1 Inhibitor TH5487 Alters OGG1 Chromatin Dynamics and Prevents Incisions
Biomolecules, 2020 8-oxoguanine DNA glycosylase (OGG1) is the main DNA glycosylase responsible for the excision of 7,8-dihydro-8-oxoguanine (8-oxoG) from duplex DNA to initiate base excision repair.

An AP endonuclease functions in active DNA demethylation and gene imprinting in Arabidopsis [corrected]. [PDF]
PLoS Genetics, 2015 Active DNA demethylation in plants occurs through base excision repair, beginning with removal of methylated cytosine by the ROS1/DME subfamily of 5-methylcytosine DNA glycosylases.

Hepatology, EarlyView., 2022 Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine. [PDF]
PLoS ONE, 2014 We demonstrate that a mutant of uracil DNA glycosylase (N123D:L191A) distinguishes between cytosine and methylcytosine. Uracil DNA glycosylase (UDG) efficiently removes uracil from DNA in a reaction in which the base is flipped into the enzyme's active ...

Frontiers in Oncology, 2022 Recently, biallelic germline variants of the DNA glycosylase genes MUTYH and NTHL1 were linked to polyposis susceptibility. Significant fractions remain without a molecular explanation, warranting searches for underlying causes.

Chicken MBD4 Regulates Immunoglobulin Diversification by Somatic Hypermutation
Frontiers in Immunology, 2019 Immunoglobulin (Ig) diversification occurs via somatic hypermutation (SHM) and class switch recombination (CSR), and is initiated by activation-induced deaminase (AID), which converts cytosine to uracil.
