Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

open access: yesAdvanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis

open access: yesAngewandte Chemie, EarlyView.
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...

G6PC Downregulation Promotes Renal Calcium Oxalate Stone Formation via Lactate‐Induced SNAIL1 K206 Lactylation and Epithelial‐Mesenchymal Transition

open access: yesAdvanced Science, EarlyView.
In renal calcium oxalate stone formation, G6PC downregulation leads to lactate accumulation. This lactate mediates CBP/p300‐dependent lactylation of SNAIL1 at K206, promoting its nuclear translocation. Nuclear SNAIL1 activates the TGF‐β/SMAD3 pathway, driving epithelial‐mesenchymal transition and fibrosis, which ultimately facilitates crystal ...

Bifurcation in epigenetics: implications in development, proliferation and diseases

open access: yes, 2014
Cells often exhibit different and stable phenotypes from the same DNA sequence. Robustness and plasticity of such cellular states are controlled by diverse transcriptional and epigenetic mechanisms, among them the modification of biochemical marks on ...

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

open access: yesAdvanced Science, EarlyView.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

Function and expression of N-acetyltransferases 1 and 2 are altered in lymphocytes in type 2 diabetes and obesity

open access: yesBiochemistry and Biophysics Reports
The cytosolic enzymes N-Acetyl Transferases 1 and 2 (NATs) transfer an acetyl group from acetyl-CoA to a xenobiotic substrate. NATs are regulated at the genetic and epigenetic levels by deacetylase enzymes such as sirtuins.

Gastrointestinal Manifestations in Rubinstein‐Taybi Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Rubinstein–Taybi syndrome is a rare genetic condition associated with a wide range of physical, cognitive, and developmental impairments, yet its gastrointestinal manifestations remain poorly characterized. Case reports and small series suggest a high prevalence of gastroesophageal reflux, constipation, dysphagia, and nutritional compromise ...

Long‐Term Follow Up of Two Patients With Variants in the Cluster 1031‐1159 of TRRAP Gene: Expanding the Phenotype of Developmental Delay With or Without Dysmorphic Facies and Autism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The transformation/transcription domain‐associated protein (TRRAP) gene encodes a large multidomain protein, a member of the phosphatidylinositol 3‐kinase‐related kinase (PIKK) family. TRRAP is a component of the histone acetyltransferase (HAT) complex, and it plays an important role in gene transcription, DNA repair, and cell‐cycle regulation.
