Journal of Biological Chemistry, 1982 A uracil-DNA-glycosylase from Micrococcus luteus has been purified more than 3,000-fold. The enzyme preparation appears homogeneous, according to the results of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It is devoid of nonspecific endonucleases, specific endonucleases for apurinic and apyrimidinic sites, 3-methyladenine or 7 ...

Insect Molecular Biology, Volume 35, Issue 3, Page 232-245, June 2026.Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

A discontinuous DNA glycosylase domain in a family of enzymes that excise 5-methylcytosine [PDF]
, 2010 DNA cytosine methylation (5-meC) is a widespread epigenetic mark associated to gene silencing. In plants, DEMETER-LIKE (DML) proteins typified by Arabidopsis REPRESSOR OF SILENCING 1 (ROS1) initiate active DNA demethylation by catalyzing 5-meC ...

Intratumoral Microorganisms in Tumors: Current Understanding and Emerging Therapeutic Strategies
MedComm, Volume 7, Issue 5, May 2026.Tumors are no longer viewed as sterile but dynamic ecosystems harboring low‐biomass intratumoral microbiota. These microbes, derived from gut, oral cavity, or circulation, shape tumorigenesis and therapy response via core mechanisms: immunomodulation (regulating T cells, macrophages), metabolic reprogramming (SCFAs, indoles, bile acids), chronic ...
