The relationship between P2X4 and P2X7: a physiologically important interaction? [PDF]

, 2013
Purinergic signaling within the kidney is becoming an important focus in the study of renal health and disease. The effectors of ATP signaling, the P2Y and P2X receptors, are expressed to varying extents in and along the nephron.

From lactation to malignancy: A comparison between healthy and cancerous breast gland at single‐cell resolution reveals new issues for tumorigenesis

FEBS Letters, EarlyView.
Single‐cell RNA sequencing reveals an opposite role of SLPI in basal tumors based on metastatic spread, along with shared activation of specific regulons in cancer cells and mature luminal lactocytes, as well as downregulation of MALAT1 and NEAT1 in the latter.

The Regulation and Function of the Amino Acid Transporters LAT1, ASCT2, xCT in Urological Cancers

Receptors
Amino acid transporters play pivotal roles in cancer biology, including in urological cancers. Among them, L-type amino acid transporter 1 (LAT1), alanine-serine-cysteine transporter 2 (ASCT2), and cystine-glutamate transporter (xCT) have garnered ...

Toll-like receptors as adjuvant receptors

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2002
The mammalian Toll-like receptors (TLRs) are expressed on macrophages and dendritic cells, which are primarily involved in innate immunity. At present, ligands for several of the TLRs, such as TLR2, TLR3, TLR4, TLR5, TLR6, and TLR9, have been identified.

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells

FEBS Letters, EarlyView.
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Short‐chain mono‐carboxylates as negative modulators of allosteric transitions in Gloeobacter violaceus ligand‐gated ion channel, and impact of a pre‐β5 strand (Loop Ω) double mutation on crotonate, not butyrate effect

Physiological Reports
Using the bacterial proton‐activated pentameric receptor‐channel Gloeobacter violaceus ligand‐gated ion channel (GLIC): (1) We characterize saturated, mono‐carboxylates as negative modulators of GLIC (as previously shown for crotonate; Alqazzaz et al ...

Glutamate Receptor Signaling in Retina Müller Cells: Plausible Role in Neurodegeneration

Receptors
The retinal network relies on glutamate, the primary excitatory neurotransmitter involved in the visual cycle. Glutamate transactions are carried out by an array of distinct receptors and transporters distributed across both pre- and post-synaptic ...

(CF3CO)2O/CF3SO3H-mediated synthesis of 1,3-diketones from carboxylic acids and aromatic ketones

Beilstein Journal of Organic Chemistry, 2014
A very simple and convenient reaction for 1,3-diketone preparation from carboxylic acids and aromatic ketones in TFAA/TfOH system is described. When the β-phenylpropionic acids were used as starting materials, they initially gave 1-indanones and then ...

Pertussis Toxin-sensitive Activation of Phospholipase C by the C5a and fMet-Leu-Phe Receptors [PDF]

, 1996
Signal transduction pathways that mediate C5a and fMet-Leu-Phe (fMLP)-induced pertussis toxin (PTx)-sensitive activation of phospholipase C (PLC) have been investigated using a cotransfection assay system in COS-7 cells.

Cancer cell death induced by the NAD antimetabolite Vacor discloses the antitumor potential of SARM1

FEBS Letters, EarlyView.
Vacor, a compound converted into the toxic metabolite Vacor adenine dinucleotide (VAD) by the nicotinamide salvage pathway enzymes NAMPT and NMNAT2, exhibits antitumor activity by inducing rapid and complete NAD depletion. We report that Vacor toxicity is limited to cell lines expressing high levels of SARM1, a NAD glycohydrolase.
