Analysis of hypoxic A549 cells treated with oligooxopiperazines (OOPs) BB2-125, BB2-162, and BB2-282. OOPs are designed mimics of a key α-helical domain at the interface of hypoxia-inducible factor 1α (HIF1α) and coactivator p300. Results provide insight into the effect of OOPs on HIF signaling.

(Submitter supplied) Hypoxia inducible factor 1 (HIF1) has been shown to cooperate with the androgen receptor (AR) in activation of oncogenic pathways in prostate cancer (PCa). Here we hypothesized that HIF1 also plays a role in PCa response to androgen deprivation therapy (ADT). Comparison of gene expression profiles of androgen exposed (AE) and androgen deprived (AD) CWR22 PCa xenografts identified 596 upregulated and 748 downregulated genes after ADT. more...

(Submitter supplied) The C-terminal activation domain (C-TAD) of the hypoxia-inducible transcription factors HIF-1? and HIF-2? binds the CH1 domains of the related transcriptional coactivators CREB-binding protein (CBP) and p300, an oxygen-regulated interaction thought to be highly essential for hypoxia-responsive transcription. The role of the CH1 domain in vivo is unknown, however. We created mutant mice bearing deletions in the CH1 domains (?CH1) of CBP and p300 that abrogate their interactions with the C-TAD, revealing that the CH1 domains of CBP and p300 are genetically non-redundant and indispensable for C-TAD transactivation function. more...

(Submitter supplied) The CH1 protein interaction domain of the transcriptional coactivators p300 and CBP is thought to interact with HIF-1alpha and this interaction is thought to be critical to the expression of HIF-1alpha target genes in response to hypoxia. Trichostatin A (TSA), an inhibitor of histone deacetylases, has been reported to repress the expression of HIF-1alpha target genes. To test the requirement of the CH1 domain and TSA for gene expression in response to dipyridyl (a hypoxia mimetic), primary mouse embryonic fibroblasts (MEFs) were generated from C57Bl/6x129/Sv F2 e14.5 embryos that contain a deletion in the CH1 domain of three of four alleles of CBP and p300. more...

(Submitter supplied) The CH1 (TAZ) domain of the transcriptional coactivators p300 and CBP has been reported to interact with the transcription factor HIF-1alpha and this interaction is thought to be critical for HIF-1alpha target gene expression in response to hypoxia. To determine the requirement for the CH1 domain in hypoxia-responsive gene expression, primary mouse embryonic fibroblasts (MEFs) were generated from e14.5 C57B/6x129/Sv F2 embryos that were either wildtype or bore deletion mutations in the CH1 protein binding domains of both alleles of p300 and one allele of CBP (tri_CH1). more...

Analysis of trichostatin A (TSA)-treated hypoxic fibroblasts with deletions in CH1 domains of p300 and CBP, and a p300 or CBP allele knockout. TSA is a histone deacetylase inhibitor. Results provide insight into the role of deacetylase activity in CH1-independent hypoxia inducible transcription.

(Submitter supplied) Transcriptional profiling of human PC-3 prostate cancer cells lentivirally infected with non-target control (NTC) short hairpin (sh)RNA comparing with lentivirally shRNA mediated human ETV4 knock-down. Cells were either cultured for 24 hours at 20% oxygen tension or 0.2% oxygen. Goal was to determine (i) genes affected by hypoxia in PC-3 NTC cells and (ii) identification of hypoxically induced genes requiring ETV4 for hypoxic regulation.
