Decitabine-mediated DNA methylation dynamics at pericentromeric satellite 2 repeats

BMC Cancer
The hypomethylating agents (HMAs) 5-azacytidine (vidaza-AZA) and 5-aza-2′-deoxycytidine (decitabine-DAC) are part of the standard of care for the treatment of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). However, the molecular events

Extrachromosomal circles of satellite repeats and 5S ribosomal DNA in human cells

Mobile DNA, 2010
Background Extrachomosomal circular DNA (eccDNA) is ubiquitous in eukaryotic organisms and was detected in every organism tested, including in humans. A two-dimensional gel electrophoresis facilitates the detection of eccDNA in preparations of genomic ...

CXCL10/SLC11A1 Axis Exacerbates Septic Liver Injury by Regulating Neutrophil Extracellular Traps Formation to Drive Macrophage Pro‑Inflammatory Polarization

Advanced Science, EarlyView.
In sepsis‐induced liver injury, marked neutrophil infiltration correlates with disease severity. Neutrophil SLC11A1 drives intracellular Fe2+ and ROS via the Fenton reaction, promoting NETs formation. Hepatocyte‐derived CXCL10 recruits neutrophils and activates the JAK/STAT1/SLC11A1 axis, enhancing NETs‐mediated inflammation.

Introducing Borsantrazole: A Trifunctional Boron‐Based Pyrazole That Extends the Lifespan of Amyotrophic Lateral Sclerosis Mice

Advanced Science, EarlyView.
Herein we report a boron‐based pyrazole, (Borsantrazole ‐ a small molecule that selectively targets oxidative stress) that significantly increases survival, reduces weight loss, delays disease onset, and affects global protein changes in the SOD1‐G37R mouse model of ALS.

Self-amplification of satellite DNA in vitro.

, 1998
We describe a PCR-like reaction in which genomic DNA acts as a template as well as a primer. Interaction between genomic tandem repeat units leads to self-amplification of satellite DNA.

A Generative Neuro‐Symbolic AI for Protein Sequence Design

Advanced Science, EarlyView.
We introduce EffieDes, a neuro‐symbolic framework coupling deep learning‐based fitness landscape parameterization with exact automated reasoning. Unlike greedy sampling, EffieDes identifies sequences that globally optimize fitness while satisfying intricate design constraints.

Condition optimization for electroporation transfection in horse skeletal muscle satellite cells

Animal Biotechnology
Satellite cells are an important cellular model for studying muscle growth and development and mammalian locomotion-related molecular mechanisms. In this study, we investigated the effects of voltage, pulse duration, and DNA dosage on horse skeletal ...

A Spatially Directed Microneedle Patch Enables Intratumoral Co‐Delivery of FOLFIRINOX, Surufatinib, and Anti‐PD‐1 for Chemo‐Immunotherapy of Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
A double‐layered shell‐core microneedle patch is developed to co‐deliver FOLFIRINOX, surufatinib, and anti‐PD‐1 for localized chemo‐immunotherapy of PDAC. This strategy achieves sustained tumor suppression, reduces metastasis, and reprograms the TME by enhancing CD8+ T‐cell infiltration and inhibiting Tregs and M2 macrophages infiltration, while ...

A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

Advanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Intermittent Fasting Restores Cardiac Lipid Homeostasis in Diabetic Cardiomyopathy in Association With Akkermansia Muciniphila and 1‐methyl‐L‐histidine

Advanced Science, EarlyView.
Intermittent fasting reshapes the gut microbiota in diabetic cardiomyopathy, restoring Akkermansia muciniphila and the microbiota‐associated metabolite 1‐methyl‐L‐histidine. This shift is linked to improved cardiac lipid homeostasis, reduced lipid peroxidation, and attenuated myocardial injury, highlighting a gut microbiota–metabolite–lipid axis in ...
