Oxidative stress upregulates the kinin B(1) receptor (B(1)R) in diabetes and hypertension. Since angiotensin II (ANG II) and endothelin-1 (ET-1) are increased in these disorders, this study aims at determining the role of these two prooxidative peptides in B(1)R expression in rat vascular smooth muscle cells (VSMC). In the A10 cell line and aortic VSMC, ANG II enhanced B(1)R protein expression ...

Activating nonshivering thermogenesis in brown adipose tissue (BAT) is a promising strategy to prevent obesity. This study investigated whether quercetin supplementation improves obesity mice by increasing BAT and white (WAT) browning. Compared high-fat diet (HFD)-fed mice, fed HFD supplemented with 1% (HFDQ) had reduced body weight total plasma cholesterol. In HFDQ-fed retroperitoneal WAT (RWA...

Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...

PC12 cells have been used extensively to study neuronal differentiation and neurite outgrowth. However, the effects of extracellular Ca2+ on not yet sufficiently evaluated. In this study, we investigated effect calcium using HS cells, which high sensitivity nerve growth factor (NGF). The addition (1 mM) medium induced outgrowth increased intracellular concentration. contrast, calcium-sensing re...

Our previous studies have shown that genistein can enhance the insulin-like growth factor (IGF)-1 receptor signalling pathway via an oestrogen receptor (ER) in human breast cancer MCF-7 cells. The present study aims to investigate how genistein regulates IGF-1 receptor expression in human MCF-7 cells. Genistein at 1 microm stimulated the growth of MCF-7 cells and this effect could be completely...

Necroptosis, as a novel concept, has been recently introduced in scientific literature. Much of our knowledge about necroptosis comes from ligation of tumor necrosis factor-α to its receptor, TNF receptor 1. Receptor-interacting protein kinase 1, receptor-interacting protein kinase 3 and its substrate, the pseudokinase mixed lineage kinase domain-like protein, have been comprehensively st...

Incubation of human distal bronchi from 48 patients for 15 h with 10(-7) M fenoterol induced sensitization characterized by an increase in maximal contraction to endothelin-1 (ET-1) and acetylcholine (ACh). Incubation of human bronchi with 10(-6), 3 x 10(-6), and 10(-5) M forskolin (an adenyl cyclase activator) reproduced sensitization to ET-1 and ACh. The sensitizing effect of fenoterol was in...

Filaggrin (FLG) is a key cornified envelope and epidermal barrier protein. FLG mutations are the most strongly implicated genetic risk factor for atopic eczema (AE). part of gene complex, called differentiation complex (EDC), genes which contribute to various aspects function. siRNA knockdown in keratinocytes caused global reduction EDC Keratin (KRT) expression concomitant with up-regulation bo...
