Nanoparticle‐Mediated Immunometabolic‐Epigenetic Remodeling Enhances Schwann Cell‐Macrophage Interaction for Sciatic Nerve Regeneration

Advanced Science, EarlyView.
A biomimetic Prussian White nanoparticle (PW) is engineered to achieve long‐term local retention and orchestrate immunometabolic‐epigenetic remodeling for sciatic nerve regeneration. PW directly targets hexokinase 2 to suppress glycolysis, thereby elevating α‐ketoglutarate and driving Kdm4a/b‐mediated demethylation of H3K9me3.

Aberrant DNA methylation of Tgfb1 in diabetic kidney mesangial cells

Scientific Reports, 2018
Epigenetic modulation may underlie the progression of diabetic nephropathy (DN). Involvement of TGFB1 in mesangial fibrosis of DN led us to hypothesize that Tgfb1 DNA demethylation contributes to progression of DN.

TET-mediated DNA hydroxymethylation is negatively influenced by the PARP-dependent PARylation

Epigenetics & Chromatin, 2022
Background Poly(ADP-ribosyl)ation (PARylation), a posttranslational modification introduced by PARP-1 and PARP-2, has first been implicated in DNA demethylation due to its role in base excision repair. Recent evidence indicates a direct influence of PARP-

Uracil-DNA Glycosylase UNG Promotes Tet-mediated DNA Demethylation [PDF]

Journal of Biological Chemistry, 2016
In mammals, active DNA demethylation involves oxidation of 5-methylcytosine (5mC) into 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) by Tet dioxygenases and excision of these two oxidized bases by thymine DNA glycosylase (TDG). Although TDG is essential for active demethylation in embryonic stem cells and induced pluripotent stem cells, it is ...

m5C‐Modified tRF3b‐CysGCA‐23 Suppresses Bladder Cancer Malignancy by Repressing H3K18 Lactylation via Stabilizing RBM4

Advanced Science, EarlyView.
In this study, we identified an NSUN6‐dependent m5C‐modified tsRNA, m5C‐tRF3b CysGCA‐23 (mtRC), that is downregulated in BC and inversely correlated with disease progression. Mechanistically, mtRC suppresses BC malignancy by stabilizing RBM4, attenuating glycolysis, and thereby limiting H3K18 lactylation–mediated activation of IL1RAP and VASH2 ...

DNA demethylation is involved in nitric oxide-induced flowering in tomato

Journal of Integrative Agriculture
Flowering is one of the most important phenological periods, as it determines the timing of fruit maturation and seed dispersal. To date, both nitric oxide (NO) and DNA demethylation have been reported to regulate flowering in plants.

Oxidative Demethylation of DNA

The FASEB Journal, 2007
Oxidative demethylation of DNA Non‐enzymatic methylation of DNA by alkylating agents such as MMS occurs at several sites, but not at the 5 position of cytosine. Instead, the main cytotoxic lesions are 3‐methyladenine, and in single‐stranded regions of DNA also 1‐methyladenine and 3‐methylcytosine.

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, EarlyView.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

DNA methylation and demethylation in adipocyte biology: roles of DNMT and TET proteins in metabolic disorders

Frontiers in Endocrinology
Adipocytes play a crucial role in regulating energy metabolism throughout the body. Dysfunctional adipocyte biology is a primary factor in the development of metabolic disorders associated with obesity and type 2 diabetes. Over the past decades, the role
