Metabotropic Glutamate Receptor 5 is a Co-Receptor for Alzheimer Aβ Oligomer Bound to Cellular Prion Protein

Neuron, 2013
SUMMARY Soluble Amyloid-β oligomers (Aβo) trigger Alzheimer’s disease (AD) pathophysiology and bind with high affinity to Cellular Prion Protein (PrPC).

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A glutamate receptor C-tail recruits CaMKII to suppress retrograde homeostatic signaling

Nature Communications, 2022
Presynaptic homeostatic plasticity adaptively enhances neurotransmitter release following diminished postsynaptic glutamate receptor functionality. Here the authors identify a calcium-independent signaling system where active CaMKII detects a short ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, Volume 20, Issue 6, Page 1556-1590, June 2026.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Domain-based identification and analysis of glutamate receptor ion channels and their relatives in prokaryotes. [PDF]

PLoS ONE, 2010
Voltage-gated and ligand-gated ion channels are used in eukaryotic organisms for the purpose of electrochemical signaling. There are prokaryotic homologues to major eukaryotic channels of these sorts, including voltage-gated sodium, potassium, and ...

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

New Perspectives in the Studies on Endocannabinoid and Cannabis: Abnormal Behaviors Associate With CB1 Cannabinoid Receptor and Development of Therapeutic Application

Journal of Pharmacological Sciences, 2004
Δ9-Tetrahydrocannabinol (Δ9-THC), the major psychoactive component of marijuana, induces catalepsy-like immobilization and impairment of spatial memory in rats. Δ9-THC also induces aggressive behavior in isolated housing stress.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Glutamate signaling through the NMDA receptor reduces the expression of scleraxis in plantaris tendon derived cells

BMC Musculoskeletal Disorders, 2017
Background A body of evidence demonstrating changes to the glutaminergic system in tendinopathy has recently emerged. This hypothesis was further tested by studying the effects of glutamate on the tenocyte phenotype, and the impact of loading and ...
