Translating the Hypoxic Response-the Role of HIF Protein Translation in the Cellular Response to Low Oxygen.

ABSTRACT: Hypoxia-Inducible Factors (HIFs) play essential roles in the physiological response to low oxygen in all multicellular organisms, while their deregulation is associated with human diseases. HIF levels and activity are primarily controlled by the availability of the oxygen-sensitive HIF? subunits, which is mediated by rapid alterations to the rates of HIF? protein production and degradation. While the pathways that control HIF? degradation are understood in great detail, much less is known about the targeted control of HIF? protein synthesis and what role this has in controlling HIF activity during the hypoxic response. This review will focus on the signalling pathways and RNA binding proteins that modulate HIF? mRNA half-life and/or translation rate, and their contribution to hypoxia-associated diseases.

Hypoxia-Inducible Factors (HIFs) play essential roles in the physiological response to low oxygen in all multicellular organisms, while their deregulation is associated with human diseases. HIF levels and activity are primarily controlled by the availability of the oxygen-sensitive HIFα subunits, which is mediated by rapid alterations to the rates of HIFα protein production and degradation.

Structural basis for Hif-1 alpha /CBP recognition in the cellular hypoxic response.

Project description:The cellular response to low tissue oxygen concentrations is mediated by the hypoxia-inducible transcription factor HIF-1. Under hypoxic conditions, HIF-1 activates transcription of critical adaptive genes by recruitment of the general coactivators CBP/p300 through interactions with its alpha-subunit (Hif-1 alpha). Disruption of the Hif-1 alpha/p300 interaction has been linked to attenuation of tumor growth. To delineate the structural basis for this interaction, we have determined the solution structure of the complex between the carboxy-terminal activation domain (CAD) of Hif-1 alpha and the zinc-binding TAZ1 (CH1) motif of cyclic-AMP response element binding protein (CREB) binding protein (CBP). Despite the overall similarity of the TAZ1 structure to that of the TAZ2 (part of the CH3) domain of CBP, differences occur in the packing of helices that can account for differences in specificity. The unbound CAD is intrinsically disordered and remains relatively extended upon binding, wrapping almost entirely around the TAZ1 domain in a groove through much of its surface. Three short helices are formed upon binding, stabilized by intermolecular interactions. The Asn-803 side chain, which functions as a hypoxic switch, is located on the second of these helices and is buried in the molecular interface. The third helix of the Hif-1 alpha CAD docks in a deep hydrophobic groove in TAZ1, providing extensive intermolecular hydrophobic interactions that contribute to the stability of the complex. The structure of this complex provides new insights into the mechanism through which Hif-1 alpha recruits CBP/p300 in response to hypoxia.

Mitochondrial dysfunction resulting from loss of cytochrome c impairs cellular oxygen sensing and hypoxic HIF-alpha activation.

Project description:While cellular responses to low oxygen (O(2)) or hypoxia have been studied extensively, the precise identity of mammalian cellular O(2) sensors remains controversial. Using murine embryonic cells lacking cytochrome c, and therefore mitochondrial activity, we show that mitochondrial reactive oxygen species (mtROS) are essential for proper O(2) sensing and subsequent HIF-1 alpha and HIF-2 alpha stabilization at 1.5% O(2). In the absence of this signal, HIF-alpha subunits continue to be degraded. Furthermore, exogenous treatment with H(2)O(2) or severe O(2) deprivation is sufficient to stabilize HIF-alpha even in the absence of cytochrome c and functional mitochondria. These results provide genetic evidence indicating that mtROS act upstream of prolyl hydroxylases in regulating HIF-1 alpha and HIF-2 alpha in this O(2)-sensing pathway.

Low glucose under hypoxic conditions induces unfolded protein response and produces reactive oxygen species in lens epithelial cells.

Project description:Aging is enhanced by hypoxia and oxidative stress. As the lens is located in the hypoglycemic environment under hypoxia, aging lens with diabetes might aggravate these stresses. This study was designed to examine whether low glucose under hypoxic conditions induces the unfolded protein response (UPR), and also if the UPR then generates the reactive oxygen species (ROS) in lens epithelial cells (LECs). The UPR was activated within 1 h by culturing the human LECs (HLECs) and rat LECs in <1.5 mM glucose under hypoxic conditions. These conditions also induced the Nrf2-dependent antioxidant-protective UPR, production of ROS, and apoptosis. The rat LECs located in the anterior center region were the least susceptible to the UPR, whereas the proliferating LECs in the germinative zone were the most susceptible. Because the cortical lens fiber cells are differentiated from the LECs after the onset of diabetes, we suggest that these newly formed cortical fibers have lower levels of Nrf2, and are then oxidized resulting in cortical cataracts. Thus, low glucose and oxygen conditions induce the UPR, generation of ROS, and expressed the Nrf2 and Nrf2-dependent antioxidant enzymes at normal levels. But these cells eventually lose reduced glutathione (GSH) and induce apoptosis. The results indicate a new link between hypoglycemia under hypoxia and impairment of HLEC functions.

DNMT3a epigenetic program regulates the HIF-2? oxygen-sensing pathway and the cellular response to hypoxia.

Project description:Epigenetic regulation of gene expression by DNA methylation plays a central role in the maintenance of cellular homeostasis. Here we present evidence implicating the DNA methylation program in the regulation of hypoxia-inducible factor (HIF) oxygen-sensing machinery and hypoxic cell metabolism. We show that DNA methyltransferase 3a (DNMT3a) methylates and silences the HIF-2? gene (EPAS1) in differentiated cells. Epigenetic silencing of EPAS1 prevents activation of the HIF-2? gene program associated with hypoxic cell growth, thereby limiting the proliferative capacity of adult cells under low oxygen tension. Naturally occurring defects in DNMT3a, observed in primary tumors and malignant cells, cause the unscheduled activation of EPAS1 in early dysplastic foci. This enables incipient cancer cells to exploit the HIF-2? pathway in the hypoxic tumor microenvironment necessary for the formation of cellular masses larger than the oxygen diffusion limit. Reintroduction of DNMT3a in DNMT3a-defective cells restores EPAS1 epigenetic silencing, prevents hypoxic cell growth, and suppresses tumorigenesis. These data support a tumor-suppressive role for DNMT3a as an epigenetic regulator of the HIF-2? oxygen-sensing pathway and the cellular response to hypoxia.

HIF-independent role of prolyl hydroxylases in the cellular response to amino acids.

Project description:Hypoxia-inducible factor (HIF) prolyl hydroxylases (PHDs) are ?-ketoglutarate (?KG)-dependent dioxygenases that function as cellular oxygen sensors. However, PHD activity also depends on factors other than oxygen, especially ?KG, a key metabolic compound closely linked to amino-acid metabolism. We examined the connection between amino-acid availability and PHD activity. We found that amino-acid starvation leads to ?KG depletion and to PHD inactivation but not to HIF stabilization. Furthermore, pharmacologic or genetic inhibition of PHDs induced autophagy and prevented mammalian target of rapamycin complex 1 (mTORC1) activation by amino acids in a HIF-independent manner. Therefore, PHDs sense not only oxygen but also respond to amino acids, constituting a broad intracellular nutrient-sensing network.

Inducers of hypoxic response: marine sesquiterpene quinones activate HIF-1.

Project description:The hypoxia-inducible factor-1 (HIF-1) transcription factor regulates cellular oxygen homeostasis. Agents that activate HIF-1 and downstream HIF targets represent potential drug leads for the prevention and/or treatment of ischemic disorders. In a search for small-molecule HIF-1 activators, 1936 marine invertebrate and algal extract samples (U.S. National Cancer Institute's Open Repository) were evaluated for HIF-1 activation activity in a cell-based reporter assay. Bioassay-guided fractionation of two active extracts of the sponge Dactylospongia elegans afforded four new sesquiterpene quinones (2-5), one new sesquiterpene phenol (6), the known Golgi disruptor ilimaquinone (1), and three previously reported ilimaquinone analogues (7-9). While antiproliferative activity was observed at higher concentrations, the sesquiterpene quinones (1-3) possessing a 2-hydroxy-5-methoxy-1,4-benzoquinone moiety activated HIF-1 and increased the expression of HIF-1 target gene vascular endothelial growth factor (VEGF) in T47D cells.

CSB protein is (a direct target of HIF-1 and) a critical mediator of the hypoxic response.

Project description:Cockayne syndrome (CS) is a rare genetic disease characterized by neurological problems, growth failure and premature ageing. Many of these features cannot simply be ascribed to the defect that CS cells display during transcription-coupled repair. Here, we show that CSB mutant cells are unable to react to hypoxic stimuli by properly activating the hypoxia-inducible factor-1 (HIF-1) pathway, a defect that is further enhanced in the event of a concomitant genotoxic stress. Furthermore, we show that CSB expression is under the control of HIF-1 and has a critical function during hypoxic response by redistributing p300 between HIF-1 and p53. Altogether, our data demonstrate that CSB is part of a feedback loop mechanism that modulates the biological functions of p53. The outcome of this study provides new insights into the understanding of the molecular basis of the CS phenotype and the involvement of the CSB protein in the hypoxic response pathway.

Tonicity enhancer binding protein (TonEBP) and hypoxia-inducible factor (HIF) coordinate heat shock protein 70 (Hsp70) expression in hypoxic nucleus pulposus cells: role of Hsp70 in HIF-1? degradation.

Project description:The objective of our study was to examine the regulation of hypoxic expression of heat shock protein 70 (Hsp70) in nucleus pulposus cells and to determine if Hsp70 promoted hypoxia-inducible factor (HIF)-1? degradation. Rat nucleus pulposus cells were maintained in culture in either 21% or 1% oxygen. To determine the regulation of Hsp70 expression by tonicity enhancer binding protein (TonEBP) and HIF-1/2, loss-of-function and gain-of-function experiments and mutational analysis of the Hsp70 promoter were performed. Hypoxia increased Hsp70 expression in nucleus pulposus cells. Noteworthy, hypoxia increased TonEBP transactivation and mutation of TonE motifs blocked hypoxic induction of the Hsp70 promoter. In contrast, mutation of hypoxia response element (HRE) motifs coupled with loss-of-function experiments suggested that HIF-1 and HIF-2 suppressed Hsp70 promoter activity and transcription. Interestingly, HIF-? interferes with TonEBP function and suppresses the inductive effect of TonEBP on the Hsp70 promoter. In terms of Hsp70 function, when treated with Hsp70 transcriptional inhibitor, KNK437, there was an increase in HIF-1? protein stability and transcriptional activity. Likewise, when Hsp70 was overexpressed, the stability of HIF-1? and its transcriptional activity decreased. Hsp70 interacted with HIF-1? under hypoxic conditions and evidenced increased binding when treated with MG132, a proteasomal inhibitor. These results suggest that Hsp70 may promote HIF-1? degradation through the proteasomal pathway in nucleus pulposus cells. In hypoxic and hyperosmolar nucleus pulposus cells, Hsp70, TonEBP, and HIFs form a regulatory loop. We propose that the positive regulation by TonEBP and negative regulation of Hsp70 by HIF-1 and HIF-2 may serve to maintain Hsp70 levels in these cells, whereas Hsp70 may function in controlling HIF-1? homeostasis.
