Severe hypoxaemic hypercapnia compounds cerebral oxidative–nitrosative stress during extreme apnoea: Implications for cerebral bioenergetic function

open access: yesThe Journal of Physiology, Volume 602, Issue 21, Page 5659-5684, 1 November 2024.
Abstract figure legend We determined how physiological extremes of O2 and CO2 impact redox regulation of cerebral bioenergetic function. World‐class breath‐hold divers performed two maximal apnoeas resulting in hypoxaemic hypercapnia (prior normoxic normoventilation) and hyperoxaemic hypercapnia (prior hyperoxic hyperventilation).

Integrated Microbiome and Metabolome Analysis Reveals Hypothalamic‐Comorbidities Related Signatures in Craniopharyngioma

open access: yesAdvanced Science, Volume 11, Issue 39, October 23, 2024.
Craniopharyngioma (CP) is an intracranial tumor with prevalent hypothalamic comorbidities. The roles of gut microbiome and serum metabolome in CP‐associated hypothalamic comorbidities are aimed to be explored. The potential of increased Clostridium is demonstrated and purine metabolism is up‐regulated as signatures of CP‐associated hypothalamic ...

Altered purinergic signaling in uridine adenosine tetraphosphate-induced coronary relaxation in swine with metabolic derangement [PDF]

open access: yes, 2017
We previously demonstrated that uridine adenosine tetraphosphate (Up4A) induces potent and partially endothelium-dependent relaxation in the healthy porcine coronary microvasculature.

Connexin 30 locally controls actin cytoskeleton and mechanical remodeling in motile astrocytes

open access: yesGlia, Volume 72, Issue 10, Page 1915-1929, October 2024.
Main Points Astroglial Cx30 interacts with the actin cytoskeleton and impairs its local remodeling during migration This alters the local membrane physical surface and migrating properties of motile astrocytes. Abstract During brain maturation, astrocytes establish complex morphologies unveiling intense structural plasticity.

The SWELL1 Channel Promotes Ischemic Brain Damage by Mediating Neuronal Swelling and Glutamate Toxicity

open access: yesAdvanced Science, Volume 11, Issue 36, September 25, 2024.
This study reveals the critical involvement of the SWELL1 channel in ischemic brain injury pathogenesis, highlighting its role in cytotoxic neuronal swelling and astrocytic glutamate excitotoxicity. Notably, pharmacological inhibition of SWELL1 by the FDA‐approved drug Dicumarol effectively blocks these deleterious pathways, underscoring SWELL1 as a ...

Extracellular ATP and its derivatives provide spatiotemporal guidance for bone adaptation to wide spectrum of physical forces

open access: yesBone Reports, 2022
ATP is a ubiquitous intracellular molecule critical for cellular bioenergetics. ATP is released in response to mechanical stimulation through vesicular release, small tears in cellular plasma membranes, or when cells are destroyed by traumatic forces ...

Inhibition of REV-ERBs stimulates microglial amyloid-beta clearance and reduces amyloid plaque deposition in the 5XFAD mouse model of Alzheimer\u27s disease [PDF]

open access: yes, 2020
A promising new therapeutic target for the treatment of Alzheimer\u27s disease (AD) is the circadian system. Although patients with AD are known to have abnormal circadian rhythms and suffer sleep disturbances, the role of the molecular clock in ...

Co-localization and functional cross-talk between A1 and P2Y1 purine receptors in rat hippocampus [PDF]

open access: yes, 2007
Adenosine and ATP, via their specific P1 and P2 receptors, modulate a wide variety of cellular and tissue functions, playing a neuroprotective or neurodegenerative role in brain damage conditions. Although, in general, adenosine inhibits excitability and

Molecular regulation of calcium‐sensing receptor (CaSR)‐mediated signaling

open access: yesChronic Diseases and Translational Medicine, Volume 10, Issue 3, Page 167-194, September 2024.
The CaSR interactome characterizes the life cycle of CaSR and its signaling capacity. (1) Extracellular calcium activates CaSR and (2) mediates intracellular G‐protein‐coupled signaling, leading to ER calcium release by generating IP3 through phospholipase C (PLC) hydrolysis of PIP2.
