Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Mass Spectrometry Imaging‐Assisted Discovery of Gallotannin Biosynthetic Genes in the Root of Paeonia suffruticosa

Advanced Science, EarlyView.
An integrated approach combining mass spectrometry imaging, transcriptomics, and phylogenetic analysis facilitated the efficient identification of genes involved in gallotannin biosynthesis in Paeonia suffruticosa. As a result, a key UGT and several SCPL acyltransferases responsible for biosynthesizing pentagalloylglucose were successfully identified ...

One‐Dimensional Polycyclic Aromatic Hydrocarbons Incorporating Multiple Dithiafulvene Units—Novel Multi‐Redox and Electrochromic Systems

Angewandte Chemie, EarlyView.
Planar polycyclic aromatic hydrocarbons (PAHs) incorporating three or four dithiafulvene (DTF) units were synthesized via Horner–Wadsworth–Emmons reactions to create large π‐conjugated redox‐active frameworks. These molecules display strong intermolecular associations and distinct odd–even redox behavior, enabling formation of mixed‐valence and radical‐

Identification of A p300–SP1–BRD4 Transcriptional Axis as a Key Driver of AR Hyperactivation in Polycystic Ovarian Syndrome

Advanced Science, EarlyView.
This study reveals a pivotal epigenetic regulatory role for the histone acetyltransferase p300, demonstrating that its acetylation of histone 3 at lysine 18 and 27 (H3K18ac and H3K27ac), alongside the formation of the p300/BRD4/SP1 complex, drives AR activation and ovarian fibrosis in PCOS.

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

Angewandte Chemie, EarlyView.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...

Acyl-CoA:Lysophospholipid Acyltransferases [PDF]

Journal of Biological Chemistry, 2009
Cell membranes contain several classes of glycerophospholipids, which have numerous structural and functional roles in the cells. Polyunsaturated fatty acids, including arachidonic acid and eicosapentaenoic acid, are located at the sn-2 (but not sn-1)-position of glycerophospholipids in an asymmetrical manner.

PIK3CA Mutations Downregulate PPT1 to Promote Adipogenesis by Suppressing P300 Depalmitoylation and Phase Separation

Advanced Science, EarlyView.
This study demonstrates that somatic PIK3CA mutations suppress PPT1 expression via activation of the PI3K–AKT–c‐JUN axis. This reduction in PPT1 weakens its interaction with P300, thereby increasing palmitoylation at C1176 of P300 and protecting P300 from lysosomal degradation.
