PolyA RNAseq from HCT116 cells in normoxia and hypoxia

ABSTRACT: To determine the effects of depleting TIP60, CDK8, or HIF1A on the transcriptional response to hypoxia, we performed RNAseq analysis of four HCT116 colorectal carcinoma cell lines (shNT, HIF1A-/-, shTIP60 and shCDK8) in normoxic and hypoxic (24hrs, 1% O2) conditions.

PolyA RNAseq from HCT116 cells in normoxia and hypoxia

Project description:To determine the effects of depleting TIP60, CDK8, or HIF1A on the transcriptional response to hypoxia, we performed RNAseq analysis of four HCT116 colorectal carcinoma cell lines (shNT, HIF1A-/-, shTIP60 and shCDK8) in normoxic and hypoxic (24hrs, 1% O2) conditions. PolyA RNA for two independent biological replicates was purified from HCT116 cells stably expressing an shRNA against a non-targeting control (shNT), TIP60 (shTIP60) or CDK8 (shCDK8), or genetically deleted HIF1A (HIF1A-/-) subjected to 24hrs 1% O2 (hypoxia) or maintained under ambient oxygen (21%; normoxia) was sequenced on the Ion Torrent platform. Reads were aligned to the human genome and gene-level counts were used for differential expression analysis.

CDK8 ChIP-seq from HCT116 cells in normoxia and hypoxia

Project description:To test if CDK8 acts directly at HIF1A target genes, we performed ChIP-seq experiments in HCT116 cells under normoxic and hypoxic conditions. ChIP-seq for CDK8 versus Input under normoxia and 24hrs hypoxia (1% O2).

Transcriptomes of CD34+ hematopoietic stem/progenitor cells (HSPCs) from myelodysplastic syndromes (MDS) patients cultured in normoxia or hypoxia.

Project description:Three MDS patients (SF3B1mut -H662/H662/Q699) and three age-matched healthy donors were challenged in colony forming assay under normoxic (20% O2) and hypoxic (3% O2) conditions. RNA-sequencing was performed on the HSPC-derived colonies o examine transcriptional changes under normoxic and hypoxic conditions.

Project description:Comparative expression analysis of vq1, vq10 and vq1vq10 versus wild type Col-0 in normoxic plants (at 21% O2) or after hypoxia treatment (4 h at 1% O2).

Secretomes of Cancer-Associated Myofibroblasts and Normal Tissue Myofibroblasts in hypoxia and normoxia C4PR_LIV

Project description:Cancer-associated fibroblasts are a major component of the cancer stroma. Here we focus on gastric cancer associated myofibroblasts (CAMs). CAMs secrete factors that increase the migration, invasion and proliferation of cancer cells when compared to adjacent tissue myofibroblasts (ATMs), or normal tissue myofibroblasts (NTMs). In this study we identified and quantified the proteins secreted by normoxic (21% O2) and hypoxic (1% O2) myofibroblast cells.

PolyA RNA-seq from HCT116 (WT and CDK8as/as) cells in normoxia or hypoxia and treated with DMSO or 3MB-PP1

Project description:To determine the impact of CDK8 kinase activity on steady-state mRNA levels, we performed RNA-seq analysis of colorectal carcinoma cell line HCT116 (CDK8wt/wt and CDK8as/as) in the presence of absence of 3MB-PP1 to specifically inhibit analog senstitive (as) CDK8.

Effect in MOLM-14 cells of 24hr cortistatin A treatment on gene expression

Project description:We characterized the marine natural product cortistatin A (CA) as an inhibitor of CDK8 to determine whether pharmacologic inhibition of CDK8 regulates super-enhancer function and inhibits AML proliferation. In this series, we examine the transcriptional effect on MOLM-14 cells of 24hrs exposure to CA.

Gene expression in human umbilical cord vein and artery endothelial cells under physiological chronic normoxia (3% O2, PCN) and standard culture normoxia (21% O2, SCN)

Project description:Endothelial cells, and many other types of cells too, physiologically reside in low O2 environments (~ 2-13% O2 or 15-60 mmHg pO2; [PCN]) relevantly to atmospheric O2 (~ 21% or 160 mmHg pO2 at sea level) in vivo. Such PCN is critical for endothelial functions. The majority of our current knowledge regarding the cellular and signaling mechanisms governing endothelial functions, however, is built on endothelial models established under atmospheric O2 (~21% O2). Herein, we comapred the transcriptional profiles between HUVE and HUAE cells cultured and expanded under PCN (3% oxygen) and standard culture normoxia (21% O2).

Homo sapiens MSCs: Normoxia vs. Hypoxia

Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.
