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

open access: yesMolecular Oncology, EarlyView.
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 ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

open access: yesFEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Ionotropic glutamate receptors (iGluRs) of the delta family (GluD1 and GluD2) and synaptogenesis

open access: yesAlexandria Journal of Medicine, 2017
Glutamate delta-1 (GluD1) and glutamate delta-2 (GluD2) form the delta family of ionotropic glutamate receptors (iGluRs) and are distinct from other (iGluRs) in that they do not exhibit typical agonist-induced ion channel currents.

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Transport of BMAA into Neurons and Astrocytes by System x\u3csub\u3ec\u3c/sub\u3e- [PDF]

open access: yes, 2018
The study of the mechanism of β-N-methylamino-l-alanine (BMAA) neurotoxicity originally focused on its effects at the N-methyl-d-aspartate (NMDA) receptor. In recent years, it has become clear that its mechanism of action is more complicated.

Dysfunctional Light-Evoked Regulation of cAMP in Photoreceptors and Abnormal Retinal Adaptation in Mice Lacking Dopamine D4 Receptors [PDF]

open access: yes, 2002
Dopamine is a retinal neuromodulator that has been implicated in many aspects of retinal physiology. Photoreceptor cells express dopamine D4 receptors that regulate cAMP metabolism.

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

open access: yesFEBS 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.

Аlterationdegree of NMDA and AMPA receptors of glutamate in the pathogenesis of the disease and technological peculiarities of surgical treatment of the hemispheric glioma-swith the epileptic syndrome

open access: yesУчёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2014
The development of effective approaches to the treatment of patients with symptomatic tumor epilepsy was determined by the level of our fundamental knowledge of the basic mechanisms of epileptogenesis on cellular and molecular level.

CNS4 causes subtype‐specific changes in agonist efficacy and reversal potential of permeant cations in NMDA receptors

open access: yesPharmacology Research & Perspectives, 2023
The NMDA subtype of glutamate receptor serves as an attractive drug target for the treatment of disorders evolving from hyper‐ or hypoglutamatergic conditions.

Neurochemical Changes in the Mouse Hippocampus Underlying the Antidepressant Effect of Genetic Deletion of P2X7 Receptors. [PDF]

open access: yes, 2013
Recent investigations have revealed that the genetic deletion of P2X7 receptors (P2rx7) results in an antidepressant phenotype in mice. However, the link between the deficiency of P2rx7 and changes in behavior has not yet been explored.
