The role of protein convertases in bigdynorphin and dynorphin A metabolic pathway
(2016-05-12)
Les dynorphines sont des neuropeptides importants avec un rôle central dans la nociception et l’atténuation de la douleur. De nombreux mécanismes régulent les concentrations de dynorphine endogènes, y compris la protéolyse. ...
Decoding protein networks during porcine reproductive and respiratory syndrome virus infection through proteomics
(2021-04-08)
Le virus du syndrome reproducteur et respiratoire porcin (VSRRP) est un pathogène de grande importance dans l'industrie porcine car il peut entraîner des pertes économiques. L'une des lignées cellulaires couramment utilisée ...
Resiniferatoxin hampers the nocifensive response of Caenorhabditis elegans to noxious heat, and pathway analysis revealed that the Wnt signaling pathway is involved
(Springer, 2021-10-25)
Resiniferatoxin (RTX) is a metabolite extracted from Euphorbia resinifera. RTX is a potent capsaicin analog with specific biological activities resulting from its agonist activity with the transient receptor potential ...
A systematic in vitro metabolism study of opioids using rat liver S9 fractions and mass spectrometry revealed CYP2D metabolism is impaired with age
(2017-03-23)
La codéine et l'oxycodone sont des opioïdes utilisés pour soulager la douleur. Le succès du traitement dépend du métabolisme par les enzymes CYP450. Selon les médicaments utilisés, l’altération de métabolisme peut entraîner ...
Is nontargeted data acquisition for target analysis (nDATA) in mass spectrometry a forward-thinking analytical approach?
(Wiley, 2022-10-21)
Targeted mass spectrometry is extensively used for the quantitative measurement of various molecules present in complex matrices. It is certainly one of the most important analytical duties in a mass spectrometry laboratory. ...
Detection and quantification of staphylococcus aureus enterotoxin B in food product using isotopic dilution techniques and mass spectrometry
(2013-01-04)
L’entérotoxine B staphylococcique (SEB) est une toxine entérique hautement résistante à la chaleur et est responsable de plus de 50 % des cas d’intoxication d’origine alimentaire par une entérotoxine. L’objectif principal ...
Effects of fibroblast growth factor 8 and 18 on ovine ovarian granulosa cell function
(2018-03-22)
Fibroblast Growth factors (FGFs) are growth factors which have diverse biological activities including broad mitogenic and cell survival activities. FGFs constitute a large family of 22 distinct polypeptide growth factors ...
Proteomics reveals long-term alterations in signaling and metabolic pathways following both myocardial infarction and chemically induced denervation
(Elsevier, 2022-06-18)
Myocardial infraction (MI) is the principal risk factor for the onset of heart failure (HF). Investigations regarding the physiopathology of MI progression to HF have revealed the concerted engagement of other tissues, ...
Antinociceptive activity of vanilloids in caenorhabditis elegans is mediated by the desensitization of the TRPV channel OCR-2 and specific signal transduction pathways
(Springer, 2023-02-03)
Vanilloids, including capsaicin and eugenol, are ligands of transient receptor potential channel vanilloid subfamily member 1 (TRPV1). Prolonged treatment with vanilloids triggered the desensitization of TRPV1, leading to ...
Characterization of Endoproteolytic Processing of Dynorphins by Proprotein Convertases using Mouse Spinal Cord S9 Fractions and Mass Spectrometry
(2016-06-01)
Dynorphins are important neuropeptides with a central role in nociception and pain alleviation. Many mechanisms regulate endogenous dynorphin concentrations, including proteolysis. Proprotein convertases (PCs) are widely ...
