A thermogenetics protocol for detecting gap junction channels in Drosophila egg chambers

STAR Protocols, 2021
Summary: In this protocol, we took a “thermogenetics” approach to detect functional gap junction channels between cells in Drosophila egg chambers. We expressed the thermosensitive cation channel TrpA1-A in the germline using Gal4, and a fluorescent [Ca2+

GPR119 Agonist AS1269574 Activates TRPA1 Cation Channels to Stimulate GLP-1 Secretion [PDF]

Molecular Endocrinology, 2016
GPR119 is a G protein-coupled receptor expressed on intestinal L cells that synthesize and secrete the blood glucose-lowering hormone glucagon-like peptide-1 (GLP-1). GPR119 agonists stimulate the release of GLP-1 from L cells, and for this reason there is interest in their potential use as a new treatment for type 2 diabetes mellitus. AS1269574 is one

Functional evidence of distinct electrophile-induced activation states of the ion channel TRPA1

Biochemistry and Biophysics Reports, 2021
Transient Receptor Potential Ankyrin 1 (TRPA1) is a tetrameric, nonselective cation channel expressed on nociceptive sensory nerves whose activation elicits nocifensive responses (e.g. pain).

Expression and distribution of the transient receptor potential cationic channel ankyrin 1 (TRPA1) in the human seminal vesicles

Health Science Reports, 2022
AbstractBackground and AimsThe transient receptor potential cationic channel ankyrin 1 (TRPA1), a channel protein permeable to most divalent cations, has been suggested to play a role in mechano‐afferent/efferent signaling (including the release of neurotransmitters) in the human urinary tract (bladder, prostate, and urethra).

The TRPA1 Channel in the Cardiovascular System: Promising Features and Challenges

Frontiers in Pharmacology, 2019
The transient receptor potential ankyrin 1 (TRPA1) channel is a calcium-permeable nonselective cation channel in the plasma membrane that belongs to the transient receptor potential (TRP) channel superfamily.

Emergence of functional sensory subtypes as defined by transient receptor potential channel expression [PDF]

, 2007
The existence of heterogeneous populations of dorsal root ganglion (DRG) neurons conveying different somatosensory information is the basis for the perception of touch, temperature, and pain. A differential expression of transient receptor potential (TRP)

Modulation of TRPA1 channel activity by Cdk5 in sensory neurons

Channels, 2018
Transient receptor potential cation channel, subfamily A, member 1 (TRPA1), is activated by a broad range of noxious stimuli. Cdk5, a member of the Cdk family, has recently been identified as a modulator of pain signaling pathways.

A novel ion channel formed by interaction of TRPML3 with TRPV5. [PDF]

, 2013
TRPML3 and TRPV5 are members of the mucolipin (TRPML) and TRPV subfamilies of transient receptor potential (TRP) cation channels. Based on sequence similarities of the pore forming regions and on structure-function evidence, we hypothesized that the pore

Transient receptor potential ankyrin 1 (trpa1) mediates il-1β-induced apoptosis in rat chondrocytes via calcium overload and mitochondrial dysfunction

Journal of Inflammation, 2018
Background Chondrocyte apoptosis is a central feature in the progression of osteoarthritis (OA), and would be triggered by sustained elevation of intracellular calcium ion (Ca2+), also known as a cellular second messenger.

Ligands Exert Biased Activity to Regulate Sigma 1 Receptor Interactions With Cationic TRPA1, TRPV1, and TRPM8 Channels [PDF]

Frontiers in Pharmacology, 2019
The sigma 1 receptor (σ1R) and the mu-opioid receptor (MOR) regulate the transient receptor potential (TRP) V1 calcium channel. A series of proteins are involved in the cross-regulation between MORs and calcium channels like the glutamate N-methyl-D-aspartate receptor (NMDAR), including the histidine triad nucleotide-binding protein 1 (HINT1 ...
