Metabolomic Profiling Reveals Key Metabolic Alterations in MCF7 Tamoxifen-Resistant Cells Following EPAS1 Inhibition

ABSTRACT:

This study aims to investigate the metabolic alterations associated with acquired tamoxifen (TAM) resistance in luminal A breast cancer cells. Using untargeted LC-MS/MS metabolomics, we compared parental MCF7 and TAM-resistant MCF7/Tam1 cells to identify key metabolic pathways affected by EPAS1 (HIF-2α)-mediated hypoxia-driven reprogramming. The study further evaluates the impact of EPAS1 inhibition by PT2977 on the reversal of these metabolic changes and restoration of TAM sensitivity.

Alteration of renal gene expression following miR-22 inhibition in rhabdomyolysis (24 h) induced acute kidney injury

Project description:In acute kidney injury (AKI) regions of the kidney are hypoxic. However, for reasons yet unknown, adaptation to hypoxia through hypoxia inducible factor (HIF) is limited. Here we seek for potential HIF repressors, their amenability to intervention, and assess the consequences for AKI outcome Renal miR-22 is up-regulated in AKI. In vitro, miR-22 is inducible by hypoxia, represses HIF, and this repression is offset by specific anti-miR-22 molecules. Inhibition of miR-22 in AKI leads to a complex regulation of more than 3,000 renal genes, most of which are unrelated to the HIF pathway.

RNA-seq on enriched cardiac fibroblasts from the hearts of Hif-1a conditional knockout or heterozygous mice

Project description:In this project we explore the role of the master hypoxia regulator, Hypoxia inducible factor-1alpha (Hif-1a), in governing cardiac fibroblast (CF) function in homeostasis. CF-specific Hif-1a conditional knockout (cKO) mice were generated by breeding Pdgfra-merCremer (PdgfraMCM/+) Cre recombinase driver mice with Hif-1a-floxed mice (Hif-1aflox/). In Hif-1afl/-; PdgfraMCM/+ progeny, Hif-1a could be conditionally deleted in adult CFs by tamoxifen (tam) administration. We also introduced a Cre-dependent R26tdTomato reporter allele allowing marking of Pdgfra+ CFs and their progeny. In this experiment, we performed bulk RNA sequencing (RNA-seq) on tdTomato+ cells from the hearts of healthy cKO or heterozygous (HET) adult, male mice.

Tuning the transcriptional response to hypoxia through HIF prolyl- and asparaginyl-hydroxylase inhibition:Sequencing Data

Project description:The hypoxia inducible factor (HIF) system orchestrates cellular responses to hypoxia in animals. HIF is an /-heterodimeric transcription factor that regulates the expression of hundreds of genes in a context dependent manner. A hypoxia-sensing component of the HIF system involves oxygen-dependent catalysis by the HIF hydroxylases; in humans there are three HIF prolyl hydroxylases (PHD1-3) and an asparaginyl hydroxylase (FIH). PHD catalysis regulates HIF levels and FIH catalysis regulates HIF activity. How differences in HIF hydroxylation status relate to variations in the induction of HIF target gene transcription is unknown. We report studies using small molecule inhibitors of the HIF hydroxylases to investigate the extent to which HIF target gene upregulation is induced by reduced PHD catalysis. The results reveal substantial differences in the role of prolyl- and asparaginyl-hydroxylation in regulating hypoxia responsive genes in cells. Selective PHD inhibitors with different structural scaffolds behave similarly. However, under the tested conditions, a broad-spectrum 2OG dioxygenase inhibitor is a better mimic of the transcriptional response to hypoxia than the selective PHD inhibitors, consistent with an important role for FIH in the hypoxic transcriptional response. Indeed, combined application of selective PHD and FIH inhibitors resulted in transcriptional induction of a subset of genes that were not fully responsive to PHD inhibition alone. Thus, for the therapeutic regulation of HIF target genes, it is important to consider both PHD and FIH activity, and in the case of some sets of target genes, simultaneous inhibition of the PHDs and FIH catalysis may be preferable.

Mitochondrial deficiency impairs hypoxic induction of HIF-1 transcriptional activity and retards tumor growth

Project description:Mitochondria can be involved in regulating cellular stress response to hypoxia and tumor growth, but little is known about that mechanistic relationship. Here, we show that mitochondrial deficiency severely retards tumor xenograft growth with impairing hypoxic induction of HIF-1 transcriptional activity. Using mtDNA-deficient rho0 cells, we found that HIF-1 pathway activation was comparable in slow-growing rho0 xenografts and rapid-growing parental xenografts. Interestingly, we found that ex vivo rho0 cells derived from rho0 xenografts exhibited slightly increased HIF-1alpha expression and modest HIF-1 pathway activation regardless of oxygen concentration. Surprisingly, rho0 cells, as well as parental cells treated with oxidative phosphorylation inhibitors, were unable to boost HIF-1 transcriptional activity during hypoxia, although HIF-1alpha protein levels were ordinarily increased in these cells under hypoxic conditions. These findings indicate that mitochondrial deficiency causes loss of hypoxia-induced HIF-1 transcriptional activity and thereby might lead to a constitutive HIF-1 pathway activation as a cellular adaptation mechanism in tumor microenvironment.

Tuning the transcriptional response to hypoxia through HIF prolyl- and asparaginyl-hydroxylase inhibition: Microarray data

Project description:The hypoxia inducible factor (HIF) system orchestrates cellular responses to hypoxia in animals. HIF is an Î±/Î²-heterodimeric transcription factor that regulates the expression of hundreds of genes in a context dependent manner. A hypoxia-sensing component of the HIF system involves oxygen-dependent catalysis by the HIF hydroxylases; in humans there are three HIF prolyl hydroxylases (PHD1-3) and an asparaginyl hydroxylase (FIH). PHD catalysis regulates HIFÎ± levels and FIH catalysis regulates HIF activity. How differences in HIFÎ± hydroxylation status relate to variations in the induction of HIF target gene transcription is unknown. We report studies using small molecule inhibitors of the HIF hydroxylases to investigate the extent to which HIF target gene upregulation is induced by reduced PHD catalysis. The results reveal substantial differences in the role of prolyl- and asparaginyl-hydroxylation in regulating hypoxia responsive genes in cells.

mTORC inhibition of neuroblastoma SK-N-BE(2)c cells cultured under hypoxic conditions

Project description:Differential expression of the oxygen sensitive hypoxia-inducible transcription factor (HIF) subunits HIF-1a and HIF-2a occurs in many tumor types, but the underlying regulatory mechanisms remain poorly understood. Here we investigate the role of mTOR complex in the regulation of HIF expression in cells cultured under hypoxic conditions. Neuroblastoma SK-N-BE(2)c cells were treated with DMSO or the mTORC complex inhibitor PP242 and cultured at hypoxia for 24, 48 or 72 hours.

Single-cell RNA-seq on enriched cardiac fibroblasts from the healthy, sham or MI hearts of Hif-1a conditional knockout or heterozygous mice

Project description:In this project we explore the role of the master hypoxia regulator, Hypoxia inducible factor-1alpha (Hif-1a), in governing cardiac fibroblast (CF) function in homeostasis and following an acute ischaemic injury - myocardial infarction (MI). CF-specific Hif-1a conditional knockout (cKO) mice were generated by breeding Pdgfra-merCremer (PdgfraMCM/+) Cre recombinase driver mice with Hif-1a-floxed mice (Hif-1aflox/). In Hif-1afl/-; PdgfraMCM/+ progeny, Hif-1a could be conditionally deleted in adult CFs by tamoxifen (tam) administration. We also introduced a Cre-dependent R26tdTomato reporter allele allowing marking of Pdgfra+ CFs and their progeny. In this experiment, we first performed single-cell RNA sequencing (scRNA-seq) on tdTomato+ cells from the hearts of healthy cKO or heterozygous (HET) adult, male mice using the 10x Genomics Chromium system. We also performed scRNA-seq on tdTomato+/CD31-/CD45- cells from the hearts of cKO or HET mice at day-3 post-sham or -MI surgery.

HIF regulatory network reflects kidney disease progression in diabetes and reversal with SGLT2 inhibition

Project description:Hypoxia drives diabetic kidney disease (DKD) progression through Hypoxia Inducible Factor (HIF) signaling. The kidney’s cellular heterogeneity and complex architecture pose challenges for directly assessing the pharmacologic effects on kidney oxygenation and hypoxia responsive pathways in vivo, such as treatment with SGLT2 inhibitors (SGLT2i), presumed to impact kidney oxygenation. Using single-cell transcriptional profiling of kidney tissue from youth with type 2 diabetes (T2D) who showed minimal clinical evidence of DKD, we identified cell type enrichment of HIF regulated genes, findings that replicated in people with later stage DKD in the Kidney Precision Medicine Project (KPMP). Using conserved transcription factor (TF) binding motifs, higher-order promoter regulatory structures identified potential cooperating TFs that explained the cell type enrichment pattern. From these promoter elements, 7 interconnected regulatory pathways were identified, comprising a network of 237 genes. Analysis of multiome data from reference tissue in KPMP demonstrated that 80% of the network genes resided in accessible chromatin. Expression of network genes increased significantly in late compared to early stage DKD and were validated in a hypoxic human organoid model system. Kidney tissue from individuals with T2D treated with SGLT2i demonstrated reversal of the accumulated changes in the HIF network compared to those not treated with SGLT2i. Most high confidence genes showed concordant differential expression in spatial transcriptomics from individuals with T2D. Hypoxic kidney organoids treated with SGLT2i confirmed these protective effects. Our promoter-anchored HIF regulatory network provides a multi-component read-out that captures disease progression and quantifies therapeutic response to SGLT2i.

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.
