Excessive DNA Double‐Strand Breaks–Associated 3D Genome Reorganization Contributes to Neural Tube Defects with Folate Deficiency

open access: yesAdvanced Science, EarlyView.
Neural tube defects (NTDs) are among the most common congenital malformations. However, the underlying etiology and mechanism remain elusive. Here, the role of DNA double‐strand breaks (DSBs) in 3D genome organization within the NTDs with folate deficiency is reported.

Activity on non-methylated DNA limits the use of endonuclease MspJI for epigenetic analyses

open access: yesAll Results Journals: Biol, 2018
Cytosine methylation of DNA in mammals has been associated with both physiological and pathological changes in gene-expression. DNA treatment with methylation sensitive and/or dependent restriction enzymes, followed by PCR amplification is a widely used ...

Revealing Cell‐Free Mitochondrial DNA Breakage Patterns as Novel Biomarkers for Sepsis

open access: yesAdvanced Science, EarlyView.
Uncovering distinct plasma cfmtDNA breakage patterns opens new frontiers for early sepsis detection and prognosis. Unique cleavage hotspots in RNR2 and COX2 regions outperform traditional biomarkers, while mechanistic insights suggest bacterial endonuclease involvement.

A Modular and Customizable CRISPR/Cas Toolkit for Epigenome Editing of Cis‐regulatory Modules

open access: yesAdvanced Science, EarlyView.
Epigenome editing surpasses genome editing in gene regulation. Modular epigenome editing frameworks are developed to interrogate cis‐regulome, enabling tunable reprogramming of cis‐elements, uncovering their epigenetic responsiveness and cross‐species portability.

The amniote-conserved DNA-binding domain of CGGBP1 restricts cytosine methylation of transcription factor binding sites in proximal promoters to regulate gene expression

open access: yesBMC Genomic Data
CGGBP1 is a GC-rich DNA-binding protein which is important for genomic integrity, gene expression and epigenome maintenance through regulation of CTCF occupancy and cytosine methylation.

Enzymatic approaches and bisulfite sequencing cannot distinguish between 5-methylcytosine and 5-hydroxymethylcytosine in DNA

open access: yesBioTechniques, 2010
DNA cytosine methylation (5mC) is highly abundant in mammalian cells and is associated with transcriptional repression. Recently, hydroxymethylcytosine (hmC) has been detected at high levels in certain human cell types; however, its roles are unknown ...

Purine and pyrimidine bases as growth substances for lactic acid bacteria [PDF]

open access: yes, 1941
In 1936 Richardson (1) showed that uracil was essential for the anaerobic growth of Staphylococcus aureus, but not for aerobic growth of the same organism.

Acidosis Forces Fatty Acid Uptake and Metabolism in Cancer Cells Regardless of Genotype

open access: yesAdvanced Science, EarlyView.
This study demonstrates that biological acidosis, commonly observed in tumors and ischemic conditions, actively promotes the protonation of fatty acids, thereby facilitating the uptake of their neutral forms. Consequently, the preference for lipid metabolism in acid‐exposed cells does not arise from genetic reprogramming that prioritizes lipids as the ...

MicroRNA‐Enriched Plant‐Derived Exosomes Alleviate Colitis by Modulating Systemic Immunity, Metabolic Homeostasis, and Gut Microbiota

open access: yesAdvanced Science, EarlyView.
Herbal medicine, with its multicomponent and multitarget potential, is often studied primarily for traditional forms, especially phytochemicals. Currently, ulcerative colitis lacks natural, low‐toxicity therapies, yet emerging research highlights plant‐derived exosomes as a promising option.

Variations in Innate Immune Cell Subtypes Correlate with Epigenetic Clocks, Inflammaging and Health Outcomes

open access: yesAdvanced Science, EarlyView.
This study uses a high‐resolution DNA methylation reference panel for 19 immune cell‐types, as well as transcriptomic, metabolomic, and large population cohort data to show that age‐related epigenetic heterogeneity within monocytes correlates with inflammaging, biological age, and all‐causemortality, and does so more strongly than existing monocyte ...
