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.

Cellular expression and crystal structure of the murine cytomegalovirus MHC-Iv glycoprotein, m153 [PDF]

, 2007
Mouse cytomegalovirus (MCMV), a β-herpesvirus that establishes latent and persistent infections in mice, is a valuable model for studying complex virus-host interactions.

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

Advanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Targeting PRKCN, an Essential Driver Orchestrating mTOR‐IRF4 Axis Independently of Kinase Activity, in Multiple Myeloma

Advanced Science, EarlyView.
Constitutive PRKCN expression is driven by super‐enhancers and modulated by NF‐κB signaling in multiple myeloma (MM). PRKCN activates mTORC1/2‐IRF4 signaling axis and favors tumor cell growth independently of its kinase activity. IRF4 reciprocally promotes PRKCN transcription, creating a feed‐forward loop.

Synergistic Tuning of Conformational Dynamics, Electron Tunneling, and Substrate Positioning Enhances Electron Transfer in a P450 Chimera for Calcifediol Biosynthesis

Advanced Science, EarlyView.
A synergistic electron transfer (ET) optimization strategy modulating conformational dynamics, ET pathway, and substrate orientation is proposed for self‐sufficient cytochrome P450s. Guided by this strategy, a P450 variant with improved ET and catalytic efficiency was identified, and the underlying molecular basis was revealed by computational analysis.

Photoenzymatic Hydroalkylation Enables Streamlined Access to Aryl Glutarimide Precursors. [PDF]

Angew Chem Int Ed Engl
We report a photoenzymatic hydroalkylation that enables streamlined, stereocontrolled access to aryl glutarimide precursors relevant to targeted protein degradation. Engineered flavin‐dependent “ene”‐reductases provide broad scope and high enantioselectivity through a distinct electron transfer–enantioselective proton transfer pathway.

SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

Advanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

NUP85 Mediates Endoplasmic Reticulum Stress through the USP47/ASK1 Signaling Pathway to Regulate the Progression of Liver Fibrosis

Advanced Science, EarlyView.
In the present study, we have demonstrated that the NUP85‐USP47‐ASK1 signaling pathway may have regulated the progression of liver fibrosis through modulating ERS. Additionally, we have developed a CREKA‐coupled liposome to target delivery of MV, a pharmacological inhibitor of NUP85, to activated HSCs, thereby attenuating liver fibrosis. ABSTRACT Liver
