PURPOSE This study investigated clinical values of corticosteroid (CS) receptor α and β in the nasal mucosa of patients with allergic rhinitis (AR) by determining CS receptor α and β mRNA expression following steroid treatment. PROCEDURES Among 120 outpatients, 65 had persistent AR, including 36 being sensitive to steroid treatment (steroid-sensitive group) and 29 being resistant to steroid t...
There is limited evidence that the tissue-protective effects of erythropoietin are mediated by a heterocomplex of the erythropoietin receptor and the β-common receptor ('tissue-protective receptor'), which is pharmacologically distinct from the 'classical' erythropoietin receptor homodimer that is responsible for erythropoiesis. However, the role of the β-common receptor and/or erythropoietin i...
Reactive oxygen species (ROS), including hydrogen peroxide (H(2)O(2)), have recently been shown to be generated upon agonism of several members of the G protein-coupled receptor (GPCR) superfamily, including β(2)-adrenergic receptors (β(2)ARs). Previously, we have demonstrated that inhibition of intracellular ROS generation mitigates β(2)AR signaling, suggesting that β(2)AR-mediated ROS generat...
UNLABELLED Recent efforts have suggested that the β-adrenergic receptor (β-AR) system may be a novel and viable therapeutic target for pain reduction; however, most of the work to date has focused on the β(2)-adrenergic receptor (AR). Here, we compared the antinociceptive effects of enantiomeric configurations of propranolol and bupranolol, two structurally similar nonselective β-blocking drugs...
The sympathetic nervous system regulates cardiac output by activating adrenergic receptors (ARs) in cardiac myocytes. The predominant cardiac ARs, β(1)- and β(2)AR, are structurally similar but mediate distinct signaling responses. Scaffold protein-mediated compartmentalization of ARs into discrete, multiprotein complexes has been proposed to dictate differential signaling responses. To test th...
Many studies indicate the involvement of WNT signaling in oncogenesis and melanoma drug resistance. Receptor-interacting protein kinase (RIPK4), which targets multiple pathways such as Wnt/β-catenin, NFKB MAPK, is might be a alternative target. This supported by fact that RIPK4 levels are elevated cells compared to normal melanocytes. Since role this regulation pathway remain unknown, we tested...
Introduction: Interferon (IFN) was first introduced by Isaacs and Linddeman in 1957. It referred to a factor that could cause inhibition in the growth of the live influenza virus. Interferons are intracellular proteins that are involved in many cellular processes such as growth, proliferation, differentiation, metabolism of the extracellular matrix, apoptosis, and regulating immune responses. T...
Introduction: The polypeptide cytokine interleukin-1 is found in all body tissues and plays its role in inflammatory changes. Interleukin-1 is known as alarm cytokine in defense mechanism, particularly immunological responses. The interleukin receptor is present in different tissues and in endometrial epithelium and its antagonist will be increased during preimplantation period, therefore it ...
Galangin can suppress hepatocellular carcinoma (HCC) cell proliferation. In this study, we demonstrated that galangin induced autophagy by activating the transforming growth factor (TGF)-β receptor/Smad pathway and increased TGF-β receptor I (RI), TGF-βRII, Smad1, Smad2, Smad3 and Smad4 levels but decreased Smad6 and Smad7 levels. Autophagy induced by galangin appears to depend on the TGF-β rec...
Protection and restoration of a functional β-cell mass are fundamental strategies for prevention and treatment of diabetes. Consequently, knowledge of signals that determine the functional β-cell mass is of immense clinical relevance. Transforming growth factor β (TGFβ) superfamily signaling pathways play a critical role in development and tissue specification. Nevertheless, the role of these p...
