LPC18:0 Secreted by Exogenous Neural Stem Cells Potentiates Neurogenesis and Functional Recovery via GPR55‐Mediated Signalling in Spinal Cord Injury

open access: yesCell Proliferation, EarlyView.
LPC18:0 secreted by exogenous neural stem cells potentiates neurogenesis via the GPR55/AKT/GSK3β signalling axis, which ultimately promotes spinal cord injury recovery. ABSTRACT Spinal cord injury (SCI) is a devastating condition with limited therapeutic options. Although neural stem cell (NSC) transplantation shows regenerative potential, its efficacy

Heat Stress Triggers Nuclear Invagination and Spatial Compartmentalization of Protein Metabolism

open access: yesCell Proliferation, EarlyView.
Cells adapt heat stress to shape a nuclear invagination region function as “protein metabolism hotspots”, where both protein production and degradation are enhanced. ABSTRACT Heat stress is a common challenge for cells, causing multiple types of cellular damage while triggering complex stress responses, including the highly conserved mechanism known as

Proteostasis of organelles in aging and disease

open access: yesThe FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Resistance‐exercise‐induced stress intervenes in TGF‐β signaling by cooperatively downregulating nuclear αB‐crystallin and SMAD4 in human skeletal muscle fibers

open access: yesThe FEBS Journal, EarlyView.
Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

open access: yesThe FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

A Multifunctional β‐Defensin‐3 Mimetic Peptide Modulates Host–Biofilm Interactions and Reduces Bone Loss in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
BDMP, a peptide that can penetrate cells and tissues, offering antimicrobial and anti‐inflammatory effects, has been identified as a potential new therapy for periodontitis. ABSTRACT Aim This study evaluated the potential of a beta‐defensin‐3 mimetic peptide (BDMP), a synthetic cell‐penetrating peptide with antimicrobial and immunomodulatory properties,

PWO proteins are associated with PRC2 since their emergence in vascular plants

open access: yesNew Phytologist, EarlyView.
Summary The Polycomb repressive complex 2 (PRC2), a conserved histone methyltransferase complex, plays a central role in transcriptional silencing across eukaryotes. Here, we investigate the evolution of PWWP‐DOMAIN INTERACTORS OF POLYCOMBS (PWOs), which interact with PRC2, and examine the conservation of the PWOs‐PRC2 interaction across plant ...

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Localisation of the Ki-67 antigen within the nucleolus: Evidence for a fibrillarin-deficient region of the dense fibrillar component [PDF]

open access: yes, 1996
The Ki-67 antigen is detected in proliferating cells in all phases of the cell division cycle. Throughout most of interphase, the Ki-67 antigen is localised within the nucleolus.
