All-Trans Retinoic Acid Attenuates Hypoxia-Induced Injury in NRK52E Cells via Inhibiting NF-x03BA;B/VEGF and TGF-β2/VEGF Pathway.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

OBJECTIVE Hypoxia has recently been proposed as one of the most important factors in progressive renal injury. Hypoxia-induced vascular endothelial growth factor (VEGF) expression may play a critical role in maintaining peritubular capillary endothelium in renal disease. This study was designed to

Retinoic Acid-Induced Protein 14 (RAI14) Promotes mTOR-Mediated Inflammation Under Inflammatory Stress and Chemical Hypoxia in a U87 Glioblastoma Cell Line.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Retinoic acid-induced 14 is a developmentally regulated gene induced by retinoic acid and is closely associated with NIK/NF-κB signaling. In the present study, we examined the effect of RAI14 on mTOR-mediated glial inflammation in response to inflammatory factors and chemical ischemia. A U87 cell

Accumulation of hypoxia-inducible factor-1 alpha protein and its role in the differentiation of myeloid leukemic cells induced by all-trans retinoic acid.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND The clinical activities of all-trans retinoic acid in the treatment of acute promyelocytic leukemia, a unique subtype of acute myeloid leukemia, have triggered extensive studies aimed at defining the mechanisms by which this compound induces differentiation of leukemic cells. Recent

HPLC-MS/MS Shows That the Cellular Uptake of All- Trans-Retinoic Acid under Hypoxia Is Downregulated by the Novel Active Agent 5-Methoxyleoligin

All-trans-retinoic acid (atRA) is the essential derivative of vitamin A and is of interest due to its various biological key functions. As shown in the recent literature, atRA also plays a role in the failing heart during myocardial infarction, the leading cause of death

Arachidonate release and c-fos expression in various models of hypoxia and hypoxia-hypoglycemia in retinoic acid differentiated neuroblastoma cells.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Hypoxia-hypoglycemia has played an important role in inducing both phospholipase A2 activation and the expression of the early gene c-fos, in the neuroblastoma cell line SK-N-BE, after it has been differentiated by retinoic acid. Under hypoxic-hypoglycemic conditions, arachidonic acid release has

Effects of all‑trans retinoic acid on VEGF and HIF‑1α expression in glioma cells under normoxia and hypoxia and its anti‑angiogenic effect in an intracerebral glioma model.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

All‑trans retinoic acid (ATRA) is one of the most potent inducers of differentiation and is capable of inducing differentiation and apoptosis in glioma cells. However, the effect of ATRA on glioma angiogenesis is yet to be elucidated. The present study investigated the effects of ATRA on the

The gene encoding human retinoic acid-receptor-related orphan receptor alpha is a target for hypoxia-inducible factor 1.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Retinoic acid-receptor-related orphan receptor (ROR) alpha is a nuclear receptor involved in many pathophysiological processes such as cerebellar ataxia, inflammation, atherosclerosis and angiogenesis. In the present study we first demonstrate that hypoxia increases the amount of Rora transcripts in

Hypoxia-induced activation of the retinoic acid receptor-related orphan receptor alpha4 gene by an interaction between hypoxia-inducible factor-1 and Sp1.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Hypoxia plays a key role in the pathophysiology of many disease states, and expression of the retinoic acid receptor-related orphan receptor alpha (RORalpha) gene increases under hypoxia. We investigated the mechanism for this transient hypoxia-induced increase in RORalpha expression. Reverse

Retinoic acid receptor-related orphan receptor (ROR) alpha4 is the predominant isoform of the nuclear receptor RORalpha in the liver and is up-regulated by hypoxia in HepG2 human hepatoma cells.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The retinoic acid receptor-related orphan receptor alpha (RORalpha) is critically involved in many physiological functions in several organs. We find that the main RORalpha isoform in the mouse liver is the RORalpha4 isoform, in terms of both mRNA and protein levels, while the RORalpha1 isoform is

Protective effect of retinoic acid receptor α on hypoxia-induced epithelial to mesenchymal transition of renal tubular epithelial cells associated with TGF-β/MMP-9 pathway.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Retinoic acid receptor α (RARα), a member of family of the nuclear retinoic acid receptors (RARs), plays an essential role in various chronic kidney diseases (CKD). Renal tubular epithelial to mesenchymal transition (EMT) is a common mechanism of progression of renal interstitial fibrosis (RIF).

Effect of all-trans-retinoic acid on the development of chronic hypoxia-induced pulmonary hypertension.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND An earlier study showed that all-trans-retinoic acid (ATRA) prevents the development of monocrotalin-induced pulmonary hypertension (PH). The purpose of the present study was to determine the effect of ATRA on another model of chronic hypoxia-induced PH. RESULTS Male Sprague-Dawley rats

Retinoic acid, hypoxia, and GATA factors cooperatively control the onset of fetal liver erythropoietin expression and erythropoietic differentiation.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The cytokine erythropoietin (Epo) is an essential factor promoting the survival, proliferation, and differentiation of erythroid progenitor cells. Epo expression and the initial phase of definitive erythropoietic differentiation in the fetal liver (E9-E12) are compromised in mouse embryos lacking

All-trans retinoic acid regulated prohibitin by retinoic acid receptor α in hypoxia-induced renal tubular epithelial cell injury.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

All-trans retinoic acid (ATRA) is a critical component in cell processes such as cell growth, differentiation and apoptosis, and it is also crucial in the regulation of extracellular matrix (ECM) deposition. Prohibitin (PHB) can regulate cell proliferation, apoptosis and differentiation. The current

All-trans retinoic acid protects renal tubular epithelial cells against hypoxia induced injury in vitro.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND It has been reported that the all-trans retinoic acid (atRA)-mediated protective effects in various cells are related to the inhibition of nuclear factor (NF)-κB activities. There exists some evidence that an increase in vascular endothelial growth factor (VEGF), which is expressed by

Effect of all-trans retinoic acid treatment on prohibitin and renin-angiotensin-aldosterone system expression in hypoxia-induced renal tubular epithelial cell injury.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

OBJECTIVE All-trans retinoic acid (ATRA) exerts various effects on physiological processes such as cell growth, differentiation, apoptosis and inflammation. Prohibitins (PHB), including prohibitin 1 (PHB1) and prohibitin 2 (PHB2), are evolutionary conserved and pleiotropic proteins implicated in
