P2Y₂ Nucleotide Receptors Expressed Heterologously in Sympathetic Neurons Inhibit Both N-Type Ca²⁺ and M-Type K⁺ Currents [PDF]

open access: yes, 1998
The P2Y₂ receptor is a uridine/adenosine triphosphate (UTP/ATP)-sensitive G-protein-linked nucleotide receptor that previously has been reported to stimulate the phosphoinositide signaling pathway.

Effect of Adenosine, Inosine Triphosphate, Uridine Triphosphate, and Adenosine Triphosphate Upon the Plasma Volume of Intact and Adrenalectomized Dogs

open access: yesExperimental Biology and Medicine, 1968
SummaryAdenosine, adenosine triphosphate, inosine triphosphate and uridine triphosphate were administered iv in 100 mg doses to intact and adrenalectomized dogs to test the ability of these compounds to increase the plasma volume. Only adenosine triphosphate was found to be effective.

Energy Metabolism Under Stress: Late‐Stage Leigh Syndrome Reveals Profound Cardiometabolic Perturbations in Ndufs4 KO Mice

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
Cardiac bioenergetic and metabolic perturbations in late‐stage Leigh syndrome. Whole‐body NDUFS4 loss severely impairs cardiac complex I activity and respiration, shifting reliance to complex II and reducing glycolytic, TCA, and amino acid‐derived energy‐generating substrates in the heart.

In vitro Assessment of RNA Polymerase I Activity

open access: yesBio-Protocol, 2017
In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...

Navigating Solute Carrier Transporters—A Comprehensive Review of Functionalized Small Molecule Probes for Target Identification and Characterization

open access: yesMedicinal Research Reviews, Volume 46, Issue 1, Page 238-271, January 2026.
ABSTRACT Solute carrier transporters (SLCs) are integral membrane proteins that play pivotal roles in maintaining cellular homeostasis by mediating the transport of a diverse range of substrates across cell membranes. With their involvement in fundamental physiological processes such as nutrient uptake, neurotransmitter signaling, and drug transport ...

Roles of transcription factors, RBPA and SIGF, in the mycobacterium tuberculosis [PDF]

open access: yes, 2016
The mechanism of prokaryotic transcription has been characterized primarily in the classic system, Escherichia coli, and cannot be confidently extended to include other prokaryotic species, such as those of the Actinobacteria phylum.

Long-term (trophic) purinergic signalling: purinoceptors control cell proliferation, differentiation and death [PDF]

open access: yes, 2010
The purinergic signalling system, which uses purines and pyrimidines as chemical transmitters, and purinoceptors as effectors, is deeply rooted in evolution and development and is a pivotal factor in cell communication.
