Ψ and χ Angle Constrains at the C‑Terminus Trp Position of the Melanotropin Tetrapeptide Ac-His‑d‑Phe-Arg-Trp-NH2 Lead to Potent and Selective Agonists at hMC1R and hMC4R

open access: yes, 2023
Melanocortin receptors (MCRs) are a family of G protein-coupled receptors that regulate important physiological functions. Yet, drug development targeting MCRs is hindered by potential side effects due to a lack of receptor subtype-selective ligands with

TRP channels in hypertension

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2007
Pulmonary and systemic arterial hypertension are associated with profound alterations in Ca(2+) homeostasis and smooth muscle cell proliferation. A novel class of non-selective cation channels, the transient receptor potential (TRP) channels, have emerged at the forefront of research into hypertensive disease states.

Pain TRPs [PDF]

open access: yesNeuron, 2005
Transient receptor potential (TRP) ion channels are molecular gateways in sensory systems, an interface between the environment and the nervous system. Several TRPs transduce thermal, chemical, and mechanical stimuli into inward currents, an essential first step for eliciting thermal and pain sensations.

TRP Channels [PDF]

open access: yesAnnual Review of Biochemistry, 2007
The TRP (Transient Receptor Potential) superfamily of cation channels is remarkable in that it displays greater diversity in activation mechanisms and selectivities than any other group of ion channels. The domain organizations of some TRP proteins are also unusual, as they consist of linked channel and enzyme domains.

TRPs in Our Senses [PDF]

open access: yesCurrent Biology, 2008
In the last decade, studies of transient receptor potential (TRP) channels, a superfamily of cation-conducting membrane proteins, have significantly extended our knowledge about the molecular basis of sensory perception in animals. Due to their distinct activation mechanisms and biophysical properties, TRP channels are highly suited to function in ...

TRP Channels in Digestive Tract Cancers. [PDF]

open access: yes, 2020
Cancers of the digestive tract are among the most prevalent types of cancer. These types of cancers are often diagnosed at a late stage, which results in a poor prognosis.

Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide. [PDF]

open access: yes, 1994
The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism.

Fluorine induced conformational switching and modulation in photophysical properties of 7-fluorotryptophan: Spectroscopic, quantum chemical calculation and molecular dynamics simulation studies

open access: yesJournal of Photochemistry and Photobiology, 2020
7-Fluorotryptophan (7F-Trp) is an important noncanonical derivative of tryptophan (Trp) amino acid which depicts high in vivo stability for the positron emission tomography imaging of Trp metabolism.

Drosophila TRPM channel is essential for the control of extracellular magnesium levels [PDF]

open access: yes, 2010
The TRPM group of cation channels plays diverse roles ranging from sensory signaling to Mg2+ homeostasis. In most metazoan organisms the TRPM subfamily is comprised of multiple members, including eight in humans. However, the Drosophila TRPM subfamily is

Evaluation of tryptophan biomass as an alternative to conventional crystalline tryptophan in broiler diets

open access: yesJournal of Applied Poultry Research, 2023
SUMMARY: The current experiment was conducted to evaluate tryptophan (Trp) biomass as an alternative to conventional crystalline Trp in broiler diets. In a growth trial, a total of 288 eight-day-old chicks were randomly allotted to 1 of 3 treatments with
