DNA methylation and DNA methyltransferases [PDF]

open access: yesEpigenetics & Chromatin, 2017
The prevailing views as to the form, function, and regulation of genomic methylation patterns have their origin many years in the past, at a time when the structure of the mammalian genome was only dimly perceived, when the number of protein-encoding ...

Multi-attribute Raman spectroscopy (MARS) for monitoring product quality attributes in formulated monoclonal antibody therapeutics

open access: yesmAbs, 2022
Rapid release of biopharmaceutical products enables a more efficient drug manufacturing process. Multi-attribute methods that target several product quality attributes (PQAs) at one time are an essential pillar of the rapid-release strategy.

Cleaving DNA with DNA [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
A DNA structure is described that can cleave single-stranded DNA oligonucleotides in the presence of ionic copper. This “deoxyribozyme” can self-cleave or can operate as a bimolecular complex that simultaneously makes use of duplex and triplex interactions to bind and cleave separate DNA substrates.

IL-22 alters gut microbiota composition and function to increase aryl hydrocarbon receptor activity in mice and humans

open access: yesMicrobiome, 2023
Background IL-22 is induced by aryl hydrocarbon receptor (AhR) signaling and plays a critical role in gastrointestinal barrier function through effects on antimicrobial protein production, mucus secretion, and epithelial cell differentiation and ...

Phosphorylating DNA with DNA [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Nearly 50 individual DNAs with polynucleotide kinase-like activity were isolated from a random-sequence pool by using in vitro selection. Each self-phosphorylating deoxyribozyme makes use of one or more of the eight standard NTPs or dNTPs as a source of activated phosphate.

Optimized design parameters for CRISPR Cas9 and Cas12a homology-directed repair

open access: yesScientific Reports, 2021
CRISPR–Cas proteins are RNA-guided nucleases used to introduce double-stranded breaks (DSBs) at targeted genomic loci. DSBs are repaired by endogenous cellular pathways such as non-homologous end joining (NHEJ) and homology-directed repair (HDR ...

Cohesin causes replicative DNA damage by trapping DNA topological stress [PDF]

open access: yes, 2020
DNA topological stress inhibits DNA replication fork (RF) progression and contributes to DNA replication stress. In Saccharomyces cerevisiae, we demonstrate that centromeric DNA and the rDNA array are especially vulnerable to DNA topological stress ...

Overall survival in patients with advanced non-small cell lung cancer with KRAS G12C mutation with or without STK11 and/or KEAP1 mutations in a real-world setting

open access: yesBMC Cancer, 2023
Background KRAS mutations occur frequently in advanced non-small cell lung cancer (aNSCLC); the G12C mutation is the most prevalent. Alterations in STK11 or KEAP1 commonly co-occur with KRAS mutations in aNSCLC.

Hyperstretching DNA [PDF]

open access: yesBiophysical Journal, 2017
AbstractThe three-dimensional structure of DNA is highly susceptible to changes by mechanical and biochemical cues in vivo and in vitro. In particular, large increases in base pair spacing compared to regular B-DNA are effected by mechanical (over)stretching and by intercalation of compounds that are widely used in biophysical/chemical assays and drug ...

Plant GARDEN: a portal website for cross-searching between different types of genomic and genetic resources in a wide variety of plant species

open access: yesBMC Plant Biology, 2023
Background Plant genome information is fundamental to plant research and development. Along with the increase in the number of published plant genomes, there is a need for an efficient system to retrieve various kinds of genome-related information from ...
