Protective role of γ ⁃ tocotrienol on muscle satellite cells of Duchenne muscular dystrophy in mice

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2022
Objective To investigate the damage of skeletal muscle satellite cells in Duchenne muscular dystrophy (DMD) and the protective effect of γ⁃tocotrienol (GT3) on muscle satellite cells in DMD knockout mice.

Cumulative Social Disadvantage and Disease Activity in Juvenile Idiopathic Arthritis: A Childhood Arthritis and Rheumatology Research Alliance Registry Study

open access: yesArthritis Care &Research, EarlyView.
Objective Social determinants of health (SDOH) contribute to juvenile idiopathic arthritis (JIA) disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship among cumulative social disadvantage ...

Defective transcription of AAGAG satellite DNA causes sex-ratio meiotic drive in Drosophila

open access: yesNature Communications
Male germ cells have complex transcriptomes, with a large fraction of the genome being transcribed. This includes protein-coding genes (often not translated), non-coding DNA, and repetitive DNA, such as transposons and satellite DNA, which are normally ...

DNA Environment of Centromeres and Non-Homologous Chromosomes Interactions in Mouse

open access: yesCells, 2021
Although the pericentromeric regions of chromosomes that are enriched in tandemly repeated satellite DNA represent a significant part of eukaryotic genomes, they remain understudied, which is mainly due to interdisciplinary knowledge gaps. Recent studies

Satellite DNA Modulates Gene Expression in the Beetle Tribolium castaneum after Heat Stress. [PDF]

open access: yesPLoS Genetics, 2015
Non-coding repetitive DNAs have been proposed to perform a gene regulatory role, however for tandemly repeated satellite DNA no such role was defined until now.

Chromosomal Differentiation of Deschampsia (Poaceae) Based on Four Satellite DNA Families

open access: yesFrontiers in Genetics, 2021
Diverse families of satellite DNA (satDNA) were detected in heterochromatin regions of Deschampsia. This kind of repetitive DNA consists of tandem repeat sequences forming big arrays in genomes, and can contribute to lineages differentiation.

Chiral Phase Change Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Defining a core configuration for human centromeres during mitosis

open access: yesNature Communications, 2023
The centromere components cohesin, CENP-A, and centromeric DNA are essential for biorientation of sister chromatids on the mitotic spindle and accurate sister chromatid segregation.

Electrostatically‐Stabilized PEG‐Free Lipid Nanoparticles for Systemic Nucleic Acid Delivery

open access: yesAdvanced Functional Materials, EarlyView.
This work describes non‐PEGylated layered lipid nanoparticles (nonPEG LLNPs), a gene delivery platform that improves upon standard PEGylated LNPs via electrostatic adsorption of charged polymers. nonPEG LLNPs maintain colloidal stability under biological stresses, enhance circulation time, and mitigate accelerated blood clearance and hepatic ...
