Vesicular glutamate transporter VGLUT2 expression emerges in substantia nigra dopamine neurons in mouse models of parkinsonism in the absence of neurodegeneration

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Subsets of midbrain dopamine (DA) neurons express the vesicular glutamate transporter VGLUT2 and can release the excitatory neurotransmitter glutamate. VGLUT2+ DA neurons of the substantia nigra pars compacta (SNc) were shown to be more resistant to neurodegeneration in animal models of Parkinson's disease (PD ...

OSA Initiates Histone Lactylation That Drives PDE4B/FUS/AGT Axis to Pulmonary Hypertension

open access: yesCell Proliferation, EarlyView.
This study illustrates how chronic intermittent hypoxia (CIH) in obstructive sleep apnea (OSA) leads to hypertension via increased oxidative stress and mitochondrial dysfunction in pulmonary artery smooth muscle cells (PASMCs), causing glycolytic dysregulation. Lactate accumulation enhances histone lactylation, upregulating phosphodiesterase 4B (PDE4B),

Growth differentiation factor 15 mitigates lipotoxic steatosis by preserving mitochondrial morphodynamics and augmenting fatty acid oxidation in hepatocytes and liver organoids

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Growth differentiation factor 15 (GDF15) has emerged as a promising metabolic regulator with hepatoprotective properties in metabolic dysfunction‐associated steatotic liver disease (MASLD), yet its underlying mechanisms remain elusive.

Hypoxia regulates Th17/Treg balance by altering chromatin accessibility and gene expression

open access: yesThe FEBS Journal, EarlyView.
T‐cell differentiation into Th17 or iTreg cells is key to inflammation control. Integrated RNA‐seq and ATAC‐seq analyses reveal that hypoxia induces more extensive gene expression changes in iTreg cells. Elevated levels of Hif1a and Stat3, along with increased accessibility to key transcription factor motifs, may predispose these cells toward ...

Effects of Rotenone and Resveratrol on Apoptosis and Oxidative Stress in Ovariectomized Rats [PDF]

open access: yesمجله دانشگاه علوم پزشکی گیلان
Background Exposure to neurotoxins increases the risk of neurodegenerative diseases. Oxidative stress and apoptosis play a central role in the initiation and progression of these disorders. Low estrogen aggravates oxidative stress and apoptosis caused by

The malate–aspartate shuttle supports thermogenic lipid mobilization in brown adipocytes

open access: yesThe FEBS Journal, EarlyView.
Brown fat cells burn lipids within their mitochondria to generate heat. This process involves two energy “shuttles,” one of which is naturally blocked during heat production. We found that the second shuttle (MASh) is not required to generate heat. However, when MASh is disabled, the fatty acids meant for fuel are instead converted back into stored fat.

Characterization of extracellular and membrane potentials in imeglimin‐treated islets

open access: yesJournal of Diabetes Investigation, EarlyView.
ABSTRACT Glucose‐stimulated insulin secretion (GSIS) in β cells depends critically on membrane depolarization–induced Ca2+ influx. Accordingly, the electrophysiological assessment of intact islets, where β cells act as functional syncytia, is essential for evaluating insulin secretory dynamics. Imeglimin, an oral agent used in treating type 2 diabetes,

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

open access: yesJournal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Metabolic Reprogramming and GM‐CSF Secretion in Areca Nut‐Activated Fibroblasts Drive Oral Precancer Progression

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective Oral cancer, with a rising global incidence and poor prognosis, is associated with areca nut use in South and Southeast Asia. In this study, we addressed the effects of areca nut extract (ANE) on oral carcinogenesis by modulating fibroblast behavior in oral tissue.
