The role of HIF-1α and HIF-2α in hypoxic and M2-polarized macrophages

ABSTRACT: Macrophages (MФ) skewn towards a regulatory-like phenotype are known to promote tumor progression. They tend to accumulate in hypoxic tumor areas and activate hypoxia-inducible factors (HIF-1 and HIF-2). HIFs are known to alter the gene expression profile of MФ. To define direct HIF-1 and HIF-2 target genes in hypoxic and IL-10 treated human MФ we used chromatin immuno-precipitation-sequencing (ChIP-seq) and microarray analysis on a genome-wide scale.

Increased HIF-2α Activity in the Nucleus Pulposus Causes Mild Degenerative Changes in the Intervertebral Disc in the Aging Mouse Spine

Project description:Transcriptomic analysis of nucleus pulposus (NP) tissues from intervertebral discs of 14- and 24-month-old mice with the conditional postnatal overexpression of HIF-2α. Hypoxia-inducible factors (HIFs) are essential for the homeostasis of the hypoxic tissues, and therefore, increased activity of the transcription factor HIF-2α is shown to contribute to the pathogenesis of mild disc degeneration in the spine. We examined the transcriptomic profiles of nucleus pulposus cells in control and K19-HIF-2α-dPA overexpression mice using microarrays.

Gene Expression profiles of colon from Hif-1α+/+, Hif-1αLSL/LSL

Project description:To investigate the detailed molecular mechanisms for the regulatory role of HIF-1α in colon, microarray gene expression analysis was performed on colon RNA isolated from 6- to 8-week-old Hif-1α+/+, Hif-1αLSL/LSL mice. Background & Aims: The progression and growth of solid tumors leads to a state where tumors outgrow their capacity for efficient oxygenation and nutrient uptake and an increase in tumor hypoxia. Tumor hypoxic response is mediated by hypoxia-inducible factor (HIF)-1a and HIF-2a. These transcription factors regulate a battery of genes that are critical for tumor oxygenation, tumor metabolism, and cell proliferation and survival. Therefore, inhibitors of HIF have been sought for as anti-neoplastic agents in several different kinds of cancers. Interestingly, in ischemic and inflammatory diseases of the intestine, activation of HIF-1a is beneficial, and can reduce intestinal inflammation. The efficacy of pharmacological agents that chronically activate HIF-1a are decreased due to the tumorigenic potential of HIF. However, recent advance in understanding HIF signaling have identified mechanisms, which could allow for isoform specific activators. Activation of HIF-2a increases colon carcinogenesis and progression in mouse models. However, the role of chronic HIF-1a activation is unclear in the progression in colon cancer. The present data demonstrates that activation of HIF-1a in epithelial cells does not increase colon carcinogens or progression in two mouse models of colon cancer, and provides the proof of principle that HIF-1a activation maybe safe as therapies for inflammatory bowel disease.

HIF-1α and HIF-2α differently regulate tumour development, metabolism and inflammation of clear cell renal cell carcinoma in mice

Project description:Mutational inactivation of VHL is the earliest genetic event in the majority of ccRCCs, leading to activation of the HIF-1α and HIF-2α transcription factors. While correlative studies of human ccRCCs and functional studies using human ccRCC cell lines have implicated HIF-1α as an inhibitor and HIF-2α as a promoter of aggressive tumour behaviours, their roles in tumour onset have not been functionally addressed. Using an autochthonous ccRCC model, we show genetically that Hif1a is necessary for tumour formation whereas Hif2a deletion has only minor effects on tumour initiation and growth. Both HIF-1α and HIF-2α are necessary for the clear cell phenotype. Transcriptomic and proteomic analyses revealed that HIF-1α regulates glycolysis while HIF-2α regulates genes associated with lipoprotein metabolism, ribosome biogenesis and E2F and MYC transcriptional activities. Deficiency of HIF-2α increased CD8+ T cell infiltration and activation. These studies reveal different functions of HIF-1α and HIF-2α in ccRCC. SIGNIFICANCE The roles of HIF-1α and HIF-2α in ccRCC pathogenesis remain unclear. Using a mouse genetic approach we show that HIF-1α but not HIF-2α is important for tumour formation, contrary to predictions from studies of human ccRCC. We show that HIF-1α and HIF-2α transcriptionally regulate different aspects of metabolism and identify HIF-2α as a suppressor of immune cell infiltration and activation.

Identification of Key HIF-1α Target Genes that Regulate Adaptation to Hypoxic Conditions in Tibetan Chicken Embryos

Project description:Background: Tibetan chicken, a unique plateau breed, has a suite of adaptive features that enable it to tolerate the high-altitude hypoxic environment. HIF‐1α (hypoxia inducible factor 1 subunit alpha) is a crucial mediator of the cellular response to hypoxia. HIF‐1α maintains oxygen homeostasis by inducing glycolysis, erythropoiesis, and angiogenesis; however, the target genes involved in adaptive responses to hypoxia in animals and birds of plateaus are still unclear. Results: We used ChIP-seq to map HIF‐1α binding regions in chorioallantoic membrane (CAM) tissue of chicken embryos, and identified 752 HIF-1α target genes (TG), of which 112 were differentially expressed target genes (DTGs) between the two breeds. We found that eight genes (PTK2, GPNMB, CALD1, SLC25A1, SPRY2, NUPL2, RANBPL, and CBWD1) play important roles in hypoxic adaption by regulating blood vessel development, energy metabolism through angiogenesis, vascular smooth muscle contraction, and various hypoxia-related signaling pathways (including VEGF and MAPK) in Tibetan chickens during embryonic development. Conclusions: This study enhances our understanding of the molecular mechanisms of hypoxic adaptation in Tibetan chickens and provides new insights into adaptation to hypoxia in humans and other species living at high altitude.

Gene expression profiling data following HIF-1α or HIF-2α knockdown in SW1353 cells

Project description:Chondrosarcomas, malignant cartilaginous neoplasms, are capable of transitioning to highly aggressive, metastatic, and treatment-refractory states, resulting in significant patient mortality. We aimed to uncover the transcriptional program directing such tumor progression in chondrosarcomas. Here, we conducted weighted correlation network analysis (WGCNA) to extract a characteristic gene module underlying chondrosarcoma malignancy. We identified hypoxia-inducible factor-2α (HIF-2α, encoded by EPAS1) as an upstream regulator that governs the malignancy gene module. HIF-2α was upregulated in high grade chondrosarcoma biopsies and HIF-2α gene amplification was associated with the poor prognosis of patients with chondrosarcoma. Using tumor xenograft mouse models, we demonstrated that HIF-2α confers chondrosarcomas the capacities required for tumor growth, local invasion, and metastasis. Pharmacological inhibition of HIF-2α in conjunction with the chemotherapy agents synergistically enhanced chondrosarcoma cell apoptosis and abolished malignant signatures of chondrosarcoma in mice. We expect that our insights into the pathogenesis of chondrosarcoma will provide guidelines for the development of novel molecular-targeted therapeutics for chondrosarcoma.

HIF- and non-HIF-Regulated Hypoxic Responses Require the Estrogen-Related Receptor in Drosophila

Project description:Low-oxygen tolerance is supported by an adaptive response that includes a coordinate shift in metabolism and the activation of a transcriptional program that is driven by the hypoxia-inducible factor (HIF) pathway. The precise contribution of HIF-1 in the adaptive response, however, has not been determined. Here we investigate how HIF-1 influences hypoxic adaptation throughout Drosophila development. We find that hypoxic-induced transcriptional changes are comprised of HIF-dependent and HIF-independent pathways that are distinct and separable. We show that normoxic set-points of carbohydrate metabolites are significantly altered in dHIF mutants and that these animals are unable to mobilize glycogen in hypoxia. Furthermore, we find that the estrogen-related receptor (dERR), which is a global regulator of aerobic glycolysis in larvae, is required for a competent hypoxic response. dERR binds to dHIF and participates in the HIF-dependent transcriptional program in hypoxia. In addition, dERR acts in the absence of dHIF in hypoxia and a significant portion of HIF-independent transcriptional responses can be attributed to dERR actions, including upregulation of glycolytic transcripts. These results indicate that competent hypoxic responses arise from complex interactions between HIF-dependent and -independent mechanisms, and that dERR plays a central role in both of these programs.
