Cowpea mosaic virus 32- and 60-kilodalton replication proteins target and change the morphology of endoplasmic reticulum membranes [PDF]

open access: yes, 2002
Cowpea mosaic virus (CPMV) replicates in close association with small membranous vesicles that are formed by rearrangements of intracellular membranes. To determine which of the viral proteins are responsible for the rearrangements of membranes and the ...

CD9+ B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression

open access: yesAdvanced Science, EarlyView.
A unique subset of CD9+ B cells regulates germinal center B (GC‐B) cell regression by inducing T follicular helper (Tfh) cell apoptosis through multiple signaling pathways, such as ALCAM‐CD6. FOXP1 plays a key role in GC‐B cell differentiation. These findings clarify mechanisms of GC degeneration and termination and offer potential targets for adenoid ...

Genetic dissection of mammalian ERAD through comparative haploid and CRISPR forward genetic screens

open access: yesNature Communications, 2016
CRISPR/Cas9-mediated forward genetic screens and gene-trap mutagenesis screens in haploid cells are both powerful techniques to examine gene function. Here, the authors show the two approaches have high concordance and identify an uncharacterized gene ...

MET Suppresses Epithelial VEGFR2 via Intracrine VEGF-induced Endoplasmic Reticulum-associated Degradation

open access: yesEBioMedicine, 2015
Hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) drive cancer through their respective receptors, MET and VEGF receptor 2 (VEGFR2). VEGFR2 inhibits MET by promoting MET dephosphorylation.

BAP31 Drives Cartilage Calcification through Disruption of Autophagosome–Lysosome Fusion in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
Mechanical stress activates BAP31 in chondrocytes. BAP31 competes with ATG14 for binding to STX17, disrupting the STX17–ATG14 complex required for autophagosome–lysosome fusion. The resultant autophagic flux blockade drives the generation of autophagy‐derived exosomes, which mediate pathological cartilage calcification in OA. Chondrocyte‐targeted BAP31

VDAC1 Upregulation Induces Hyperexcitability of Nociceptive Sensory Neurons Via Enhanced Mitochondrial Atp Efflux in Neuropathic Pain

open access: yesAdvanced Science, EarlyView.
The mechanism diagram of VDAC1 mediating neuronal excitability and neuropathic pain. Briefly, VDAC1 is expressed in DRG neurons and is upregulated following CCI‐induced neuropathic pain. This upregulation enhances ATP transport from mitochondria to the cytoplasm in sensory neurons, leading to increased neuronal excitability and pain behavior.

Sel1l preserves condylar cartilage matrix homeostasis by regulating PERK signaling

open access: yesInterdisciplinary Medicine
Temporomandibular joint osteoarthritis (TMJOA) is a degenerative disease with orofacial pain and impaired joint function. However, the mechanisms are not well understood.

Loss of E3 Ubiquitin Ligase RINES via CpG Methylation Relieves Suppression of STAT3 and MYC, Facilitating Multiple Tumorigeneses

open access: yesAdvanced Science, EarlyView.
Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

Penfluridol Triggers GSDME‐Mediated Immunogenic Pyroptosis to Potentiate Antitumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
A high‐throughput screen of FDA‐approved antipsychotics identifies penfluridol as a potent pyroptosis inducer acting via direct TTI1 inhibition. This triggers TNFA‐NFKB signaling and caspase‐8/‐3‐dependent GSDME cleavage. The compound stimulates antitumor immunity alone and synergizes with anti‐PD‐1 therapy, while low TTI1 expression emerges as a ...

ER stress-mediated apoptosis in a new mouse model of osteogenesis imperfecta [PDF]

open access: yes, 2008
Osteogenesis imperfecta is an inherited disorder characterized by increased bone fragility, fractures, and osteoporosis, and most cases are caused by mutations affecting the type I collagen genes.
