VCP‐Regulated LMF2 Stabilizes the Cholesterol Biosynthesis Enzyme HMGCS1 to Drive Cancer Progression and Confer Capecitabine Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
LMF2 drives progression and capecitabine resistance in triple‐negative breast cancer (TNBC). Mechanistically, VCP prevents NBR1‐mediated autophagic degradation of LMF2, thereby stabilizing it. Stabilized LMF2 subsequently suppresses NDP52‐mediated autophagic degradation of HMGCS1, a rate‐limiting cholesterol biosynthesis enzyme.

A thermodynamic assay to test pharmacological chaperones for Fabry disease.

Biochim Biophys Acta, 2014
The majority of the disease-causing mutations affect protein stability, but not functional sites and are amenable, in principle, to be treated with pharmacological chaperones. These drugs enhance the thermodynamic stability of their targets. Fabry disease, a disorder caused by mutations in the gene encoding lysosomal alpha-galactosidase, represents an ...

Polyphosphate Copper Nanospheres Drive Mitochondrial Metabolic Reprogramming via Calcium Phase Separation for Self‐Sensitizing Cuproptosis

Advanced Science, EarlyView.
This study developed polyphosphate (polyP)‐based nanostructures that enable calcium‐mediated metabolic reprogramming via liquid–liquid phase separation (LLPS). Released polyP undergoes LLPS with Ca2+, suppressing glycolytic flux and enhancing mitochondrial metabolism effectively.

Hepatocyte CBX2 Safeguards Hepatic Lipid Homeostasis by Elevating Ca2+‐CaMKK2‐AMPK Signaling to Counter MASLD

Advanced Science, EarlyView.
In hepatocytes, CBX2 promotes H3K4me3 enrichment at the Orai1 promoter to enhance Orai1 transcriptional activation, thereby increasing intracellular Ca2+ levels. The elevated Ca2+ activates the CaMKK2‐AMPK signaling cascade, resulting in ACC phosphorylation and downstream metabolic regulation. This cascade suppresses de novo lipogenesis (Fasn, Acc, Scd‐

Exploring the efficacy and safety of Ambroxol in Gaucher disease: an overview of clinical studies

Frontiers in Pharmacology
Gaucher disease (GD) is mainly caused by glucocerebrosidase (GCase) enzyme deficiency due to genetic variations in the GBA1 gene leading to the toxic accumulation of sphingolipids in various organs, which causes symptoms such as anemia, thrombocytopenia,

CaMKIIδ Phosphorylates AUP1 to Promote Pancreatic Tissue Repair and Acinar‐to‐Ductal Metaplasia Formation via Mediating PERK‐Dependent Unfolded Protein Responses

Advanced Science, EarlyView.
CaMKIIδ–AUP1 signaling maintains PERK‐dependent ER homeostasis during ADM‐mediated pancreatic repair. ABSTRACT Pancreatic repair after acute pancreatitis (AP) is essential for restoring tissue integrity, but the intrinsic mechanisms coordinating acinar plasticity and regeneration remain poorly understood.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

AI-based discovery and cryoEM structural elucidation of a KATP channel pharmacochaperone

eLife
Pancreatic KATP channel trafficking defects underlie congenital hyperinsulinism (CHI) cases unresponsive to the KATP channel opener diazoxide, the mainstay medical therapy for CHI. Current clinically used KATP channel inhibitors have been shown to act as

Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.
