Augmented generation of protein fragments during wakefulness as the molecular cause of sleep: A hypothesis [PDF]
, 2012 Despite extensive understanding of sleep regulation, the molecular-level cause and function of sleep are unknown. I suggest that they originate in individual neurons and stem from increased production of protein fragments during wakefulness.

Squalene-Adenosine Nanoparticles: Ligands of Adenosine Receptors or Adenosine Prodrug? [PDF]
The Journal of Pharmacology and Experimental Therapeutics, 2019 Adenosine receptors (ARs) represent key drug targets in many human pathologies, including cardiovascular, neurologic, and inflammatory diseases. To overcome the very rapid metabolization of adenosine, metabolically stable AR agonists and antagonists were developed.

Developmental, Neuroanatomical and Cellular Expression of Genes Causing Dystonia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Dystonia is one of the most common movement disorders, with variants in multiple genes identified as causative. However, an understanding of which developmental stages, brain regions, and cell types are most relevant is crucial for developing relevant disease models and therapeutics.

A2B Adenosine Receptor and Cancer [PDF]
International Journal of Molecular Sciences, 2019 There are four subtypes of adenosine receptors (ARs), named A1, A2A, A2B and A3, all of which are G protein-coupled receptors (GPCRs). Locally produced adenosine is a suppressant in anti-tumor immune surveillance. The A2BAR, coupled to both Gαs and Gαi G proteins, is one of the several GPCRs that are expressed in a significantly higher level in certain

Advanced Functional Materials, EarlyView.This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

Adenosine receptors and cancer
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2011 Adenosine is a ubiquitous signaling molecule whose physiological functions are mediated by its interaction with four G-protein-coupled receptor subtypes, termed A(1), A(2A), A(2B) and A(3). As a result of increased metabolic rates, this nucleoside is released from a variety of cells throughout the body in concentrations that can have a profound impact ...
