Extracellular ATP is increased by release of ATP-loaded microparticles triggered by nutrient deprivation
(Pubmed, 2022-01)Rationale: Caloric restriction improves the efficacy of anti-cancer therapy. This effect is largely dependent on the increase of the extracellular ATP concentration in the tumor microenvironment (TME). Pathways for ATP ... -
Triplet photosensitizer-nanotube conjugates: synthesis, characterization and photochemistry of charge stabilizing, palladium porphyrin/carbon nanotube conjugates
(Royal Society of Chemistry, 2020-04-22)The ability of a triplet photosensitizer to generate long-lived charge separated states, in contrast to traditionally used singlet photosensitizers, in covalently functionalized single-walled carbon nanotube hybrids has ... -
N-Doped graphene/C60 covalent hybrid as a new material for energy harvesting applications
(Royal Society of Chemistry, 2018-08-27)N-Doped graphene (N-G)was chemically functionalized byN-alkylationwith the well-known electron acceptor C60. The degree of functionalization and the key structural features of the N-G/C60 hybrid were systematically investigated ... -
Formation and Photoinduced Electron Transfer in Porphyrin- and Phthalocyanine-Bearing N-Doped Graphene Hybrids Synthesized by Click Chemistry
(Wiley-VCH, 2022-03-07)Graphene doped with heteroatoms such as nitrogen, boron, and phosphorous by replacing some of the skeletal carbon atoms is emerging as an important class of two-dimensional materials as it offers the much-needed bandgap ... -
A genomics approach identifies selective effects of trans-resveratrol in cerebral cortex neuron and glia gene expression.
(CNRS, 2017-04)The mode of action of trans-resveratrol, a promising lead compound for the development of neuroprotective drugs, is unknown. Data from a functional genomics study were retrieved with the aim to find differentially expressed ... -
Adenosine Metabolism in the Cerebral Cortex from Several Mice Models during Aging
(MDPI, 2020-10)Adenosine is a neuromodulator that has been involved in aging and neurodegenerative diseases as Alzheimer’s disease (AD). In the present work, we analyzed the possible modulation of purine metabolites, 5’nucleotidase ... -
Antitumoral Action of Resveratrol Through Adenosinergic Signaling in C6 Glioma Cells
(Frontiers, 2021-09)Gliomas are the most common and aggressive primary tumors in the central nervous system. The nucleoside adenosine is considered to be one major constituent within the tumor microenvironment. The adenosine level mainly ... -
Adenosine and Metabotropic Glutamate Receptors Are Present in Blood Serum and Exosomes from SAMP8 Mice: Modulation by Aging and Resveratrol
(MDPI, 2020-06)Adenosine (ARs) and metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors (GPCRs) that are modulated in the brain of SAMP8 mice, an animal model of Alzheimer’s disease (AD). In the present work, it is ... -
The antioxidant resveratrol acts as a non-selective adenosine receptor agonist
(Elsevier, 2019-05)Resveratrol (RSV) is a natural polyphenolic antioxidant with a proven protective role in several human diseases involving oxidative stress, although the molecular mechanism underlying this effect remains unclear. The present ... -
