RNA-seq profiling of transcriptomes of control and Hif1a mutant E12.5 hearts

ABSTRACT: Purpose: to identify genes aberrantly expressed upon myocardial ablation of Hif1a Methods: a floxed Hif1a allele was deleted in mouse embryonic hearts using a NXK2.5Cre line. Total RNA was extracted from E12.5 hearts (n=3 for controls and mutants) usinz Trizol and processed for RNA-seq. Reads were mapped to Mm10 reference genome using TopHat2 and Bowtie2. Transcript expression values were determined after transcript normalization with AltAnalyze Results: this analysis revealed a total of 1451 genes significantely (|Fold| > 20% and P<0.05) modulated in Hif1a cKO hearts 6 total RNAseq runs with 3 experimental samples and 3 controls samples

ChIP-seq profiling of loci bound by HIF1a in wild-type E12.5 hearts

Project description:Purpose: to identify genes directly bound by HIF1a in cardiomycoytes Methods: crosslinked chromatin isolated from E12.5 mouse hearts was precipitated using an anti-HIF1a antibody and processed for sequencing. A list of genes containing a HIF1a peak (Minimum score 3.5) was compared with RNA-seq results to identify genes that are bound by HIF1a and expressed in E12.5 hearts Results: this analysis identified 1016 genes expressed and bound by HIF1a in embryonic hearts

Gene expression profiling in WT and Hif1a-/- HSCs

Project description:To understand the underlying mechanism by which the Hif1a gene is required by hematopoietic stem cells (HSCs), we performed a comparative DNA microarray analysis using total RNA isolated from wild type Lin-Sca-1+c-Kit+ cells and Hif1a-/- Lin-Sca-1+c-Kit+ cells. The result was validated by quantitative real-time PCR analysis of wild type Lin-Sca-1+c-Kit+ and Hif1a-/- Lin-Sca-1+c-Kit+ cells. We compared the gene profile of HSCs between WT mice and Hif1a-/- mice.

KIMAT1 and HIF1A-As2 silencing RNA-seq

Project description:In our study, we valided the important oncogeneic roles of KIMAT1 and HIF1A-As2 in non-small cell lung cancer. We used custom designed GapmeRs to silence the KIMAT1 and HIF1A-As2 in H1299 and performed RNA-seq. 11389 and 7767 genes were regulated by KIMAT1 and HIF1A-As2, respectively.

KIMAT1 and HIF1A-As2 silencing small RNA-seq

Project description:In our study, we valided the important oncogeneic roles of KIMAT1 and HIF1A-As2 in non-small cell lung cancer. We used custom designed GapmeRs to silence the KIMAT1 and HIF1A-As2 in H1299 and performed small RNA-seq. 214 and 233 microRNAs were regulated by KIMAT1 and HIF1A-As2, respectively.

FOXA1 inhibits prostate cancer hypoxia program through transcriptional repression of HIF1A

Project description:We and others have previously shown FOXA1 is frequently mutated or downregulated in castration resistant prostate cancer (CRPC). Here we report a novel role for transcription factor FOXA1 in directly repressing HIF1A expression in prostate cancer cells. FOXA1 knockdown induced the expression of HIF1A and hypoxia signature genes, which were reduced by concomitant HIF1A knockdown or treatment with HIF1A inhibitor KC7F2. Thus, our data suggest FOXA1 loss induces aberrant hypoxia signaling and tumor progression in part via HIF1A.

Genome-wide maps of HIF1a binding sites in ccRCC cell line under hypoxia condition

Project description:We report the application of chromatin immunoprecipitation and next generation sequencing technology for HIF1a binding sites at genome wide level in a RCC (renal cell carcinoma) cell line under hypoxia conditions. We found HIF1a binding sites in Caki-2 cell line under hypoxia conditions. Especially, we found HIF1a bind to SPOP under hypoxia condition, which was further validated.

HIF1A signaling selectively supports proliferation of breast cancer in the brain [HIF1A KD]

Project description:Blood-borne metastasis to the brain is a major complication of breast cancer, but cellular pathways that enable cancer cells to selectively grow in the brain microenvironment are poorly understood. We find that cultured circulating tumor cells (CTCs), derived from blood samples of women with advanced breast cancer and directly inoculated into the mouse frontal lobe, exhibit striking differences in proliferative potential in the brain. Derivative cell lines generated by serial intracranial injections acquire selectively increased proliferative competency in the brain, with reduced orthotopic tumor growth. Increased Hypoxia Inducible Factor 1A (HIF1A)-associated signaling correlates with enhanced proliferation in the brain, and shRNA-mediated suppression of HIF1A or drug inhibition of HIF-associated glycolytic pathways selectively impairs brain tumor growth while minimally impacting mammary tumor growth. In clinical specimens, brain metastases have elevated HIF1A protein expression, compared with matched primary breast tumors, and, in patients with brain metastases, hypoxic signaling in CTCs predicts decreased overall survival. The selective activation of hypoxic signaling by metastatic cancers in the brain may be an opportunity for therapeutic intervention.
