M6A Modified miR‐31‐5p Suppresses M1 Macrophage Polarization and Autoimmune Dry Eye by Targeting P2RX7

Advanced Science, EarlyView.
The upregulation of FTO in autoimmune dry eye suppresses the recognition of pri‐miR‐31 by DGCR8, thereby inhibiting the maturation of miR‐31‐5p and reducing its inhibitory effect on the target gene P2RX7. The activation of P2RX7 subsequently triggers the p38 MAPK signaling pathway and increases the level of M1‐related genes, thus exacerbating the ...

Senescent cells: A therapeutic target for osteoporosis

Cell Proliferation, Volume 55, Issue 12, December 2022., 2022
Bone is a metabolically active tissue involved in physiological processes of locomotion, support and protection of soft tissues, calcium and phosphate storage, and harbouring of bone marrow. Bone is constituted by various types of cells undergoing continuous remodelling.

Genome-wide identification and comparative analysis of cytosine-5 DNA methyltransferases and demethylase families in wild and cultivated peanut

Frontiers in Plant Science, 2016
DNA methylation plays important roles in genome protection, regulation of gene expression and was associated with plants development. Plant DNA methylation pattern was mediated by cytosine-5 DNA methyltransferases and demethylase. Although the genomes of

RACK7 Interacts with PRC2 Complex to Regulate Astrocyte Development

Advanced Science, EarlyView.
The study investigates the role of RACK7 in brain development using a conditional knockout mouse model. RACK7 deficiency results in developmental defects and abnormal astrocyte development by disrupting H3K27me3 chromatin binding. The underlying mechanism involves RACK7 interacting with the PRC2 complex to regulate the genomic localization of SUZ12 and

Exosome‐shuttled mitochondrial transcription factor A mRNA promotes the osteogenesis of dental pulp stem cells through mitochondrial oxidative phosphorylation activation

Cell Proliferation, Volume 55, Issue 12, December 2022., 2022
Exosomes increase mitochondrial transcription factor A (TFAM) expression in DPSCs by transferring TFAM mRNA. Moreover, highly expressed TFAM in DPSCs enhances GDH expression and OXPHOS activity. Meanwhile, glutamate metabolism provides amounts of NADH to OXPHOS.

Specific low frequency electromagnetic fields induce epigenetic and functional changes in U937 cells [PDF]

arXiv, 2018
In this study, we investigated the effects of specific low frequency electromagnetic fields sequences on U937 cells, an in vitro model of human monocyte/macrophage differentiation. U937 cells were exposed to electromagnetic stimulation by means of the SyntheXer system using two similar sequences, XR-BC31 and XR-BC31/F.

ALKBH3‐Mediated M1A Demethylation of METTL3 Endows Pathological Fibrosis:Interplay Between M1A and M6A RNA Methylation

Advanced Science, EarlyView.
RNA modification is crucial in fibrosis diseases, but the role of m1A modification remains elusive. This study reveals that ALKBH3, an m1A demethylase, drives skin fibrosis by reshaping m6A RNA modification and stabilizing COL1A1 and FN1 mRNAs through METTL3, uncovering a crosstalk between m1A and m6A methylation in pathological events.

Leucine‐Rich Repeat‐Containing G Protein‐Coupled Receptor 6 Ameliorates Pressure Overload‐Induced Cardiac Hypertrophy by Regulating Cardiomyocyte Metabolic Reprogramming

Advanced Science, EarlyView.
LGR6 overexpression ameliorates cardiac hypertrophy by regulating metabolic reprogramming through USP4‐PPARα pathway. Abstract Metabolic reprogramming is a pivotal mechanism in the pathogenesis of pathological cardiac hypertrophy. Leucine‐rich repeat‐containing G protein‐coupled receptor 6 (Lgr6) has emerged as a significant player in cardiovascular ...

HP1a targets the Drosophila KDM4A demethylase to a subset of heterochromatic genes to regulate H3K36me3 levels. [PDF]

PLoS ONE, 2012
The KDM4 subfamily of JmjC domain-containing demethylases mediates demethylation of histone H3K36me3/me2 and H3K9me3/me2. Several studies have shown that human and yeast KDM4 proteins bind to specific gene promoters and regulate gene expression. However,

STING Agonists and How to Reach Their Full Potential in Cancer Immunotherapy

Advanced Science, EarlyView.
STING agonists show promise in preclinical studies in boosting an anti‐tumor response using the immune system. However, different limitations remain, and future research is needed to better understand how STING activation impacts the tumor microenvironment, identify effective combination strategies, and determine the best tumor types for STING agonist ...
