From DNA Methylation Microarray to Digital PCR: A Stepwise Strategy for Tissue Specific cfDNA Biomarker Development

Journal of Clinical Laboratory Analysis, EarlyView.
Overview of a DNA methylation biomarker development pipeline, from discovery and assay design to screening, performance evaluation, and specificity testing in clinical sample matrices. ABSTRACT Background Tissue‐specific cell‐free DNA (cfDNA) offers promise as a minimally invasive biomarker of organ injury.

Irradiation and Alterations in Hippocampal DNA Methylation

Epigenomes
The response of the brain to radiation is important for cancer patients receiving whole or partial brain irradiation or total body irradiation, those exposed to irradiation as part of a nuclear accident or a nuclear war or terrorism event, and for ...

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Enhanced C‐To‐T and A‐To‐G Base Editing in Mitochondrial DNA with Engineered DdCBE and TALED

Advanced Science
Mitochondrial base editing with DddA‐derived cytosine base editor (DdCBE) is limited in the accessible target sequences and modest activity. Here, the optimized DdCBE tools is presented with improved editing activity and expanded C‐to‐T targeting scope ...

Restriction and modification in Bacillus subtilis: gene coding for a BsuR-specific modification methyltransferase in the temperate bacteriophage Φ3T [PDF]

, 1981
The resistance of Phi3T DNA to degradation by the restriction enzyme BsuR or its isoschizomer HaeIII is due to obligatory modification of such DNA. Biochemical and genetical experiments indicate that Phi3T codes for a methyltransferase, which methylates ...

Bioanalytical TERS and Advanced Data Processing Methods

Journal of Raman Spectroscopy, EarlyView.
Tip‐enhanced Raman spectroscopy delivers label‐free, subnanometer vibrational imaging of biological systems. Recent advances in instrumentation, data analysis, and ambient/liquid operation enable surface‐selective mapping of molecular heterogeneity in proteins, nucleic acids, membranes, and viruses, positioning TERS as a powerful platform for nanoscale

Chloroplast DNA methylation in the kelp Saccharina latissima is determined by origin and possibly influenced by cultivation

Evolutionary Applications
DNA cytosine methylation is an important epigenetic mechanism in genomic DNA. In most land plants, it is absent in the chloroplast DNA. We detected methylation in the chloroplast DNA of the kelp Saccharina latissima, a non‐model macroalgal species of ...

New Insights into 5hmC DNA Modification: Generation, Distribution and Function

Frontiers in Genetics, 2017
Dynamic DNA modifications, such as methylation/demethylation on cytosine, are major epigenetic mechanisms to modulate gene expression in both eukaryotes and prokaryotes.

FXTAS and the Spectrum of FMR1 Premutation‐Associated Phenotypes in Latin America: A Scoping Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Fragile X–associated tremor/ataxia syndrome (FXTAS) is a late‐onset neurodegenerative disorder caused by FMR1 premutation expansions (55–200 CGG repeats). Although well described in populations of predominantly European ancestry, FXTAS remains poorly characterized in Latin America due to limited awareness, restricted access to ...

Extreme Peripheral Blood Plasmacytosis Mimicking Plasma Cell Leukemia as a Presenting Feature of Angioimmunoblastic T-Cell Lymphoma (AITL). [PDF]

, 2019
Angioimmunoblastic T-cell lymphoma (AITL) is one of four major subtypes of nodal peripheral T cell lymphoma, characterized by its cell of origin, the follicular helper T-cell (TFH).
