Hypoxia-inducible factor-1 alpha (HIF-1alpha) and its role in the hypoxic preconditioning and gene expression patterns in zebrafish ( Danio rerio) embryos
Preconditioning to lowered oxygen levels (hypoxia) may occur when an animal is subjected to non-lethal levels of hypoxia and then returned to normoxic conditions. During a subsequent exposure to hypoxia, the pre-exposed animals may exhibit increased tolerance compared to naive animals. I have …

Inhibition of progestin-induced VEGF in mammary cancer by curcumin and 2-methoxy estradiol and their potential role as anti-angiogenic & chemopreventive compounds
… tumor cells, of vascular endothelial growth factor (VEGF), a potent angiogenic growth factor. In the present study I show that curcumin, a turmeric root derivative, and 2-methoxyestradiol (2ME2), a natural metabolite of estradiol, effectively inhibit progestin-induced VEGF secretion from …

Influence of Preoperative Transcatheter Arterial Chemoembolization on Gene Expression in the HIF-1α Pathway in patients with Hepatocellular Carcinoma
… Since TACE induces hypoxic necrosis in tumors, hypoxia-inducible factor 1α (HIF-1α) could critically affect biology in residual tumors after TACE treatment and subsequent prognosis. However, HIF-1α and its prognostic relevance in TACE have rarely been examined in human …

Different Effect of 5-Fluorouracil on Expression of Genes Related to Aerobic Glycolysis According to Chemoresponsiveness in Gastric Cancer Cells
… aerobic glycolysis pathway which depends on the hypoxia-inducible factor 1α (HIF 1α). I investigated HIF1α expression and responsiveness to 5-FU in two different types of gastric cancer cells (MKN45, SNU216). In addition, we checked the change of the expressions of aerobic …

Chronic Hypoxia Induces Epigenetic Modifications in the Fetal Rat Heart
… of stress during gestation as a risk factor for heart diseases has expanded. We now know that events in utero can significantly alter gene expression patterns in heart tissue leading to increase susceptibility to ischemia reperfusion injury in adulthood. The focus of this project was …

Defining the Role of Secondary DNA Structures and Transcription Factors on the Transcriptional Control of the HIF-1alpha and VEGF Promoters
… in tumors by the constant expression of the hypoxia inducible factor 1 alpha (HIF-1α) and human vascular endothelial growth factor (VEGF). In fact, tumor recurrence, aggressive metastatic legions and patient mortality rates are known to be positively correlated with overexpression of these …

The Role of Adenosine Signaling In Mature Erythrocytes and Erythroid Progenitors
… bodies. It is highly induced particularly under hypoxia or energy depletion conditions. Adenosine functions as a critical ligand, after binding to membrane-associated adenosine receptors, adenosine initiates a downstream signaling cascade and subsequently contributes to functions of nervous …

Chronic Hypoxia and Cardiovascular Dysfunction in Sleep Apnea Syndrome
… study was to test the hypothesis that chronic hypoxia associated with sleep-disordered breathing relates to abnormal Nitric Oxide (NO) production and vascular endothelial growth factor (VEGF) expression patterns that contribute to aberrancy of specific determinates of cardiovascular and …

Normal Glycolytic Enzyme Activity Is Critical For Hypoxia Inducible Factor-1A Activity and Provides Novel Targets For Inhibiting Tumor Growth
… Glycolytic Enzyme Activity is Critical for Hypoxia Inducible Factor-1α Activity and Provides Novel Targets for Inhibiting Tumor Growth</p> <p>By Geoffrey Grandjean</p> <p>Advisory Professor: Garth Powis, D. Phil</p> <p>Unique to proliferating cancer cells is the observation that their …

The Hypoxic Adenosine Response Modulates Macrophage Differentiation and Contributes to Lung Disease
… on AAMs, and inhibition or genetic silencing of hypoxia inducible factor 1a (HIF1A) as a means to attenuate pro-fibrotic mediator production and pulmonary fibrosis in bone marrow derived macrophages (BMDMs) and in vivo models of bleomycin-induced pulmonary fibrosis. These players will be valuable …

Regulation of cellular glucose metabolism by HIV-1 infection
… glucose metabolism pathway via the Vpr-hypoxia inducible factor 1 alpha (HIF-1 alpha) axis to induce expression of hexokinase (HK), glucose-6-phosphate dehydrogenase (G6PD) and pyruvate kinase muscle type 2 (PKM2) that facilitates viral replication and biogenesis, and long-term survival …

MT1-MMP enhances cell survival and proliferation via roles unrelated to metabolic transcript levels in MCF7 breast cancer cells
Membrane-type 1 matrix metalloproteinase (MT1-MMP) is a multifunctional protease implicated in cancer aggressiveness for its ability to promote proliferation, migration, and invasion, particularly at low expression levels. Due to its multidomain structure and cell signalling abilities, MT1-MMP may …
