Glutamine Metabolism: Molecular Regulation, Biological Functions, and Diseases

open access: yesMedComm, Volume 6, Issue 7, July 2025.
Tumor cells adapt to nutrient‐poor environments by altering metabolism to acquire essential nutrients. They convert glutamine into glutamate and α‐ketoglutarate, supporting mTOR activation and sugar biosynthesis. Disruption of mTORC1 signaling is linked to disease, while glutamine and leucine activation promotes cell growth and inhibits autophagy ...

Chronic cocaine enhances release of neuroprotective amino acid taurine: a microdialysis study [PDF]

open access: yes, 2008
Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^.

Light‐Activated Pharmacological Tools for Exploring the Cholinergic System

open access: yesMedicinal Research Reviews, Volume 45, Issue 4, Page 1251-1274, July 2025.
ABSTRACT Cholinergic transmission plays a critical role in both the central and peripheral nervous systems, affecting processes such as learning, memory, and inflammation. Conventional cholinergic drugs generally suffer from poor selectivity and temporal precision, leading to undesired effects and limited therapeutic efficacy. Photopharmacology aims to

Liquiritigenin‐Rich Hydroalcoholic Extract of Brazilian Red Propolis Reduces Dyskinesia Induced by 3,4‐ Dihydroxyphenylalanine in Hemiparkinsonian Rats

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 137, Issue 1, July 2025.
ABSTRACT The set‐up and progression of dyskinesia induced by 3,4‐dihydroxyphenylalanine (L‐DOPA) are strongly linked to oxidative stress and neuroinflammation. The aim of this work was to study and characterize the effects of the hydroalcoholic extract of Brazilian red propolis (HERP) on L‐DOPA–induced dyskinesia (LID) in hemiparkinsonian rats injected
