Hypoxia plays a significant role in solid tumors by the increased expression of hypoxia-inducible factor-1α (HIF-1α), which is known to promote cancer invasion and metastasis. Cancer-cell invasion dynamically begins with the degradation of the extracellular matrix (ECM) via invadopodia formation.
Intermittent hypoxia (IH) has been found to protect brain from ischemic injury. We investigated whether IH mitigates brain oxidative stress and behavioral deficits in rats subjected to ethanol intoxication and abrupt ethanol withdrawal (EW). The effects of IH on overt EW behavioral signs, superoxide
Abrupt cessation of chronic alcohol consumption triggers signaling cascades that harm vulnerable brain regions and produce neurobehavioral deficits. We have demonstrated that a program of intermittent, normobaric hypoxia training (IHT) in rats prevents brain damage and neurobehavioral impairment
In this study, functional magnetic resonance imaging (fMRI) was used to evaluate in vivo hepatic oxygenation changes in chronically ethanol (CE)-treated and pair-fed (PF) control rats. Male Wistar rats were pair-fed an all-liquid diet containing 36% of total calories as either ethanol or
The mechanical, haemodynamic, and energetic functions of isolated perfused working hearts from chronic alcoholic and control rats were studied. Male Long-Evans rats were fed a nutritionally-complete liquid diet containing 38% of daily calories as ethanol (isocaloric replacement with dextrin-maltose
OBJECTIVE
Alcoholic liver disease (ALD) is characterized by gut dysbiosis and increased gut permeability. Hypoxia inducible factor 1α (HIF-1α) has been implicated in transcriptional regulation of intestinal barrier integrity and inflammation. We aimed to test the hypothesis that HIF-1α plays a
