Clinical value of significance of hypoxia inducible factor-1α, glucose transporter-1 and carbonic anhydrase IX in rectal cancer after preoperative chemoradiotherapy
(2019)Purpose: The standard treatment of rectal cancer is surgery along with preoperative radiotherapy, administered alone or in combination with chemotherapy. Preoperative chemoradiotherapy (preCRT) is widely used as it allows ... -
ERK signaling controls productive HIF-1 binding to chromatin and cancer cell adaptation to hypoxia through HIF-1α interaction with NPM1
(2021)The hypoxia-inducible factor HIF-1 is essential for oxygen homeostasis. Despite its well-understood oxygen-dependent expression, regulation of its transcriptional activity remains unclear. We show that phosphorylation by ... -
An exploratory study of radiation dermatitis in breast cancer patients
(2018)Background/Aim: Radiation dermatitis is observed in 95% of breast cancer patients receiving radiotherapy. The aim of this study was to explore the correlation between protein expression in tumor cells and the risk of ... -
Expression of AGPAT2, an enzyme involved in the glycerophospholipid/triacylglycerol biosynthesis pathway, is directly regulated by HIF-1 and promotes survival and etoposide resistance of cancer cells under hypoxia
(2018)Hypoxia inducible factor-1 (HIF-1) supports survival of normal cells under low oxygen concentration and cancer cells in the hypoxic tumor microenvironment. This involves metabolic reprogramming via upregulation of glycolysis, ... -
HIF-1α in colorectal carcinoma: Review of the literature
(2015)Colorectal cancer (CRC) is the third most common cancer worldwide and despite the abundance of molecular pathways and markers continually being reported, the mortality rates remain high. Hypoxia inducible f actor lalpha ... -
HIF-1α-derived cell-penetrating peptides inhibit ERK-dependent activation of HIF-1 and trigger apoptosis of cancer cells under hypoxia
(2019)Hypoxia is frequently encountered in the microenvironment of solid tumors. Hypoxia-inducible factors (HIFs), the main effectors of cell response to hypoxia, promote cancer cell survival and progression. HIF-1α, the ... -
Hypoxia upregulates integrin gene expression in microvascular endothelial cells and promotes their migration and capillary-like tube formation
(2017)Tissue hypoxia affects gene expression through the hypoxia-inducible transcription factors, HIF-1 and HIF-2, in both physiological and pathological angiogenesis. Angiogenesis is a complex response of endothelial cells ... -
Hypoxia-induced Changes in SUMO Conjugation Affect Transcriptional Regulation under Low Oxygen
(2019)Hypoxia occurs in pathological conditions, such as cancer, as a result of the imbalance between oxygen supply and consumption by proliferating cells. HIFs are critical molecular mediators of the physiological response to ... -
Hypoxia-inducible factor 1-alpha and vascular endothelial growth factor in cartilage tumors
(2019)Neoangiogenesis has been demonstrated in chondrosarcoma. Anti-angiogenic therapies are being tested in clinical trials for chondrosarcomas. Studies of the underlying mechanisms have been performed almost exclusively in ... -
Identification of MAPK phosphorylation sites and their role in the localization and activity of hypoxia-inducible factor-1α
(2006)Hypoxia-inducible factor 1 (HIF-1) controls the expression of most genes induced by hypoxic conditions. Regulation of expression and activity of its inducible subunit, HIF-1α, involves several post-translational modifications. ... -
Indoleamine 2, 3-dioxygenase Up-regulates Hypoxia-inducible Factor-1α Expression by degrading l-Tryptophan but not its activity in human alloreactive t-cells
(2018)Indoleamine 2, 3-dioxygenase (IDO) suppresses T-cell function at least in part by altering cell metabolism. Hypoxia-inducible factor-1 (HIF-1) increases upon T-cell activation and alters cell metabolism favoring their ... -
Inhibition of Malate Dehydrogenase-2 Protects Renal Tubular Epithelial Cells from Anoxia-Reoxygenation-Induced Death or Senescence
(2022)Ischemia-reperfusion injury is the leading cause of acute kidney injury. Reactive oxygen species (ROS) production causes cell death or senescence. In cultures of primary human renal tubular epithelial cells (RPTECs) subjected ... -
Mortalin-mediated and ERK-controlled targeting of HIF-1α to mitochondria confers resistance to apoptosis under hypoxia
(2017)Hypoxia inducible factor-1 (HIF-1) is the main transcriptional activator of the cellular response to hypoxia and an important target of anticancer therapy. Phosphorylation by ERK1 and/or ERK2 (MAPK3 and MAPK1, respectively; ... -
Protein phosphatase PPP3CA (calcineurin A) down-regulates hypoxia-inducible factor transcriptional activity
(2019)Hypoxia-inducible factors (HIF) are master regulators of the response to hypoxia. Although several kinases are known to modify their oxygen sensitive HIF-α subunits or affect indirectly their function, little is known about ... -
Reoxygenation induces reactive oxygen species production and ferroptosis in renal tubular epithelial cells by activating aryl hydrocarbon receptor
(2021)During the reperfusion phase of ischemia‑reper‑ fusion injury, reactive oxygen species (ROS) production aggravates the course of many diseases, including acute kidney injury. Among the various enzymes implicated in ROS ... -
The role of hypoxia-inducible factor-2 alpha in angiogenesis
(2018)Angiogenesis is a key enabling feature of mammalian embryonic development and tumor progression, which provides oxygen and nutrients that are required for vessel growth and tumor cell growth, respectively. Hypoxia is a ... -
