Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

Advanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Tendon Organoids Enable Functional Tendon Rejuvenation Through ALKBH5‐Dependent RNA Demethylation

Advanced Science, EarlyView.
FT organoids reverse the aged phenotype of tendon cells, reinstating a fetal‐like state. This breakthrough establishes a potent cell source for tendon tissue engineering, effectively advancing regenerative medicine. ABSTRACT Adult tendon injuries pose a major clinical challenge due to limited self‐repair capacity, resulting in suboptimal regeneration ...

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

Fibroblast Activation Protein Promotes Thoracic Aortic Dissection via PLAUR/ITGB1‐Mediated Pro‐inflammatory Macrophage Polarization

Advanced Science, EarlyView.
This study reveals that FAP promotes thoracic aortic dissection (TAD) through a nonenzymatic mechanism involving fibroblast‐macrophage crosstalk via the FAP/PLAUR/ITGB1/FAK axis. Targeting this pathway might offer a promising therapeutic strategy for TAD.

Irgm1 Improves Postinfarction Cardiac Repair by Promoting Neutrophil Clearance and Efferocytosis

Advanced Science, EarlyView.
The Irgm1‐PDIA3 axis enhances post‐infarction cardiac repair by accelerating neutrophil clearance and facilitating efferocytosis. Irgm1 holds potential as a prognostic biomarker in MI, and LOC14 may represent a therapeutic option to improve cardiac repair, especially in cases of Irgm1 deficiency.

Dissecting regulatory non-coding GWAS loci reveals fibroblast causal genes with pathophysiological relevance to heart failure

Nature Communications
Heart failure is caused in part by cardiac remodeling processes that include the death of cardiac myocytes and their replacement by cardiac fibroblasts.

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

Advanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

Advanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.

Measuring cellular traction forces on non-planar substrates

, 2016
Animal cells use traction forces to sense the mechanics and geometry of their environment. Measuring these traction forces requires a workflow combining cell experiments, image processing and force reconstruction based on elasticity theory.
