Objective(s): The aim of this study was to identify the role of miR-155 in the myocardial ischemia/reperfusion (I/R) injury through targeting hypoxia-inducible factor 1-alpha (HIF-1α). Materials and Methods: We constructed rat models with myocardial I/R injury and H9C2 cell models with hypoxia/reoxygenation (H/R) damage. Anti-miR-155 and...
MicroRNAs have been implicated in ischemic AKI. However, the specific microRNA species that regulates ischemic kidney injury remains unidentified. Our previous microarray analysis revealed microRNA-489 induction in kidneys of mice subjected to renal ischemia-reperfusion. In this study, we verified the induction of microRNA-489 during ischemic AKI in mice and further examined the underlying mech...
OBJECTIVE The chondrocytes, the resident cells of cartilage, are maintained and take effects in the whole life upon chronic hypoxic exposure, which hypoxia-inducible factor 1 alpha (HIF-1α) play pivotal roles in response to. Dysregulation of some microRNA (miRNAs) have also been identified to be involved in hypoxia-related physiologic and pathophysiologic responses in some tissues or cell lines...
BACKGROUND AND PURPOSE The usefulness of hyperbaric oxygen (HBO) and normobaric hyperoxia in acute ischemic stroke is being reexplored because both improve outcome in experimental cerebral ischemia. However, even the basic mechanisms underlying oxygen therapy are poorly understood. We investigated the effect of both oxygen therapies on tissue hypoxia and on the transcription factor hypoxia-indu...
RATIONALE The AMP-activated protein kinase (AMPK) is stimulated by hypoxia, and although the AMPKα1 catalytic subunit has been implicated in angiogenesis, little is known about the role played by the AMPKα2 subunit in vascular repair. OBJECTIVE To determine the role of the AMPKα2 subunit in vascular repair. METHODS AND RESULTS Recovery of blood flow after femoral artery ligation was impaire...
Background: This research intended to discover the significance of miR-138 (microRNA 138) on expression profile, proliferation, and associated regulatory mechanisms in prostate cancer (PCa). Methods: Thirty-five specimens were studied evaluate level miR138 by RT-qPCR (Quantitative reverse transcription polymerase chain reaction). Bioinformatics analysis was performed search for target genes miR...
Hypoxia-inducible factor 1-alpha (HIF-1 α ) and some microRNA (miRNAs) play pivotal roles in response to hypoxia-related physiologic and pathophysiologic responses. Up to date, the regulatory mechanisms of these molecules were largely unknown in chondrocytes. In this study, to study the mechanisms of degradation and homeostasis of chondrocytes, the effects of miRNAs and HIF-1 α on chondrocytes ...
