Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Histone Acetylation Dynamics Integrates Metabolic Activity to Regulate Plant Response to Stress

open access: yesFrontiers in Plant Science, 2019
Histone lysine acetylation is an essential chromatin modification for epigenetic regulation of gene expression during plant response to stress. On the other hand, enzymes involved in histone acetylation homeostasis require primary metabolites as ...

Different Behavioral Experiences Produce Distinctive Parallel Changes in, and Correlate With, Frontal Cortex and Hippocampal Global Post-translational Histone Levels. [PDF]

open access: yes, 2018
While it is clear that behavioral experience modulates epigenetic profiles, it is less evident how the nature of that experience influences outcomes and whether epigenetic/genetic biomarkers could be extracted to classify different types of behavioral ...

Microenvironment Modulation‐Based Nanomaterial‐Loaded Hydrogel Dressings for Diabetic Foot Ulcers: Research Progress and Future Perspectives

open access: yesAdvanced Materials Interfaces, EarlyView.
xx xx. ABSTRACT Diabetic foot ulcer (DFU) is a chronic complication of diabetes, primarily caused by hyperglycemia, peripheral vascular disease, and neuropathy. Characterized by persistent hyperglycemia, impaired perfusion, inflammation, and infection, DFUs pose significant challenges to healing and are associated with high morbidity and amputation ...

Erasers of Histone Acetylation: The Histone Deacetylase Enzymes [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2014
Histone deacetylases (HDACs) are enzymes that catalyze the removal of acetyl functional groups from the lysine residues of both histone and nonhistone proteins. In humans, there are 18 HDAC enzymes that use either zinc- or NAD(+)-dependent mechanisms to deacetylate acetyl lysine substrates.

Phase‐Separation of YAP Mediates AJUBA Super Enhancer Activation to Promote Aberrant Mitosis in Breast Cancer

open access: yesAdvanced Science, EarlyView.
YAP undergoes phase separation to activate the AJUBA super‐enhancer, driving aberrant mitosis through spindle checkpoint dysregulation in breast cancer. This study uncovers a mechanistic link between YAP condensates, super‐enhancer activation, and aneuploidy formation.

Plant responses to abiotic stress regulated by histone acetylation

open access: yesFrontiers in Plant Science
In eukaryotes, histone acetylation and deacetylation play an important role in the regulation of gene expression. Histone acetylation levels are reversibly regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs).

ACL and HAT1 form a nuclear module to acetylate histone H4K5 and promote cell proliferation

open access: yesNature Communications, 2023
Acetyl-CoA utilized by histone acetyltransferases (HAT) for chromatin modification is mainly generated by ATP-citrate lyase (ACL) from glucose sources. How ACL locally establishes acetyl-CoA production for histone acetylation remains unclear.

HDAC-mediated control of ERK- and PI3K-dependent TGF-β-induced extracellular matrix-regulating genes [PDF]

open access: yes, 2010
Histone deacetylases (HDACs) regulate the acetylation of histones in the control of gene expression. Many non-histone proteins are also targeted for acetylation, including TGF-ß signalling pathway components such as Smad2, Smad3 and Smad7. Our studies in

Acetyl-CoA synthetase regulates histone acetylation and hippocampal memory [PDF]

open access: yesNature, 2017
Metabolic production of acetyl coenzyme A (acetyl-CoA) is linked to histone acetylation and gene regulation, but the precise mechanisms of this process are largely unknown. Here we show that the metabolic enzyme acetyl-CoA synthetase 2 (ACSS2) directly regulates histone acetylation in neurons and spatial memory in mammals.
