Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

open access: yesAdvanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

Randomized preclinical study of machine perfusion in vascularized composite allografts

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

β‐Adducin Restrains PLA2G4A‐Dependent Lysosomal Membrane Permeabilization and Neuronal Death in Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
This study identifies β‐adducin as a regulator of lysosomal integrity in ischemic neurons. Ischemia‐associated FTO loss increases m6A modification and destabilizes Add2 mRNA, reducing β‐adducin expression and promoting PLA2G4A accumulation at lysosomes.

RBMS1 Contributes to Early Arteriovenous Fistula Neointimal Remodeling Through Modulation of VSMC Phenotypic Responses

open access: yesAdvanced Science, EarlyView.
Postoperative arteriovenous fistulas exhibit increased RBMS1 in vascular smooth muscle cells (VSMCs). In experimental AVFs, RBMS1 overexpression aggravates, whereas deletion attenuates, neointimal hyperplasia. RBMS1 binds MPZL1 mRNA and promotes exon 5 skipping to generate MPZL1‐Δ5, which interacts with G3BP1 to activate AKT, driving VSMC proliferation,

NCLX Inhibition plus Ca2+ Delivery Potentiates Electroporation and Antitumor Immunity in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
Electroporation combined with NCLX inhibition and Ca2+ delivery induces mitochondrial Ca2+ overload in PDAC cells, triggering pyroptosis, DAMP release, and antitumor immune activation. Simultaneously, suppression of tumor‐derived SPP1 weakens SPP1–CD44 signaling and remodels macrophages toward an antitumor phenotype, thereby enhancing CD8+ T‐cell ...

Macrophage GLUD1 is Essential for Redox Balance and Immune Homeostasis in Cardiac Injury

open access: yesAdvanced Science, EarlyView.
Excessive free radical production and dysregulated immune responses are key contributors to myocardial ischemia‐reperfusion (IR) injury. Macrophage GLUD1 activity safeguards against HIF‐1α accumulation and maladaptive responses to IR‐induced ROS production.

Lactate Homeostasis Disruption Potentiates TACE‐Immunotherapy in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
Lactate homeostasis is disrupted through spatially coordinated extracellular neutralization and intracellular acidification, triggering calcium overload, mitochondrial dysfunction, and immunogenic cell death. This metabolic reprogramming alleviates the immunosuppressive tumor microenvironment and enhances immune checkpoint blockade, providing a ...

Review of breast arterial calcifications for cardiovascular disease risk prediction

open access: yesnpj Cardiovascular Health
Breast arterial calcification (BAC), frequently visible on screening mammography, is a potent biomarker for cardiovascular disease risk in women. Unlike atherosclerosis, BAC represents medial arterial calcification characterized by arterial stiffness ...

RUNX1‐Mediated Hypoxic Signaling Impairs Myogenesis and Promotes Fibrosis in Myopathies

open access: yesAdvanced Science, EarlyView.
Myofiber overgrowth was associated with reduced blood flow and a potential hypoxic state in broiler breast muscle, accompanied by increased RUNX1 expression. Elevated RUNX1 impaired myogenic regeneration, promoted fibrosis, and disrupted the signaling niche required for efficient muscle repair, contributing to pathological degeneration in Wooden Breast
