Transient receptor potential (TRP) channels are nonselec-tive cation channels (mainly Ca 2+) that play critical roles as cellular sensors, including contributions to vision, taste, olfaction, hearing, touch, and thermo-, chemo-and osmo-sensation. The activation of a TRP channel changes the membrane potential, translocates important signaling ions cross the cell membrane, alters enzyme activity ...
Purpose: Indoleamine 2,3-dioxygenase 1 (IDO1: IDO), an enzyme catabolizing tryptophan (Trp) into the kynurenine (Kyn) pathway, is increasingly being recognized as an important microenvironmental factor suppressing antitumor immune responses. The purpose of the present study was to determine the prognostic significance of Trp catabolism in adult T-cell leukemia/lymphoma (ATL). Experimental Desig...
Despite the advances in detection of and therapies for various tumors, high rates of treatment failure and mortality still exist throughout the world. These high rates are mainly due to the powerful capability of tumor cells to proliferate and migrate. Recent studies regarding the transient receptor potential (TRP) have indicated that TRP channels are associated with tumors and that TRP channel...
The 20 residue Trp-cage mini-protein is one of smallest proteins that adopt a stable folded structure containing also well-defined secondary structure elements. The hydrophobic core is arranged around a single central Trp residue. Despite several experimental and simulation studies the detailed folding mechanism of the Trp-cage protein is still not completely understood. Starting from fully ext...
Abstract Background Psoriasis is a chronic and non-transient disease with increased epidermal proliferation in the skin. Dysregulation of immune system an important factor this pathology. Inflammation markers, pro-inflammatory cytokines, cells are reported to be changed psoriasis. Study design In current cohort study, possible changes interleukin-6 (IL-6), neopterin levels, kynurenine (Kyn) pat...
Nine isotopomers of tryptamine and its halogen derivatives, labeled with deuterium, tritium in side chain, i.e., [(1R)-2H]-, [(1R)-3H]-, 5-F-[(1R)-2H]-, 5-F-[(1R)-3H]-, 5-Br-[(1R)-2H]-, double labeled [(1R)-2H/3H]-, 5-F-[(1R)-2H/3H]-, and ring labeled [4-2H]-, and [5-2H]-tryptamine, were obtained by enzymatic decarboxylation of l-Trp and its appropriate derivatives in deuteriated or tritiated m...
The TRP superfamily of cation channels encompasses 28 mammalian members related to the product of the Drosophila trp (transient receptor potential) gene. TRP channels have a widespread distribution in many cell types and organs and gate in response to a broad variety of physical and chemical stimuli; as such, they can be considered as ubiquitous cellular sensors. Several recent studies reported...
The effect of berry phenolics such as anthocyanins, ellagitannins, and proanthocyanidins from raspberry (Rubus idaeus), black currant (Ribes nigrum), and cranberry (Vaccinium oxycoccus) and byproducts of deoiling processes rich in phenolics such as rapeseed (Brassica rapa L.), camelina (Camelina sativa), and soy (Glycine max L.) as well as scots pine bark (Pinus sylvestris) was investigated in ...
Mutations in the Drosophila retinal degeneration A (rdgA) gene, which encodes diacylglycerol kinase (DGK), result in early onset retinal degeneration and blindness. Whole-cell recordings revealed that light-sensitive Ca2+ channels encoded by the trp gene were constitutively active in rdgA photoreceptors. Early degeneration was rescued in rdgA;trp double mutants, lacking TRP channels; however, t...
