Cellular response to hypoxia on human bronchial epithelial culture [scRNA-Seq CAP]

ABSTRACT: Purpose: To identify the cell types change and gene expression change under hypoxia on HBE cells. Methods: The primary human bronchial epithelial cells (HBE) were cultured on air-liquid interface (ALI) conditions. After 4 weeks, the cells were cultured under normoxic, symmetrical hypoxic (3.5% O2), or asymmetrical hypoxic (3.5% O2 basolateral with apical cap ~ 1% O2) conditions for 5 days. The cells were dissociated with Accutase solution and proceeded to scRNA-seq. Results: Asymmetrical hypoxic cells showed more hypoxia-related responses than symmetrical hypoxic cells.

Cellular response to hypoxia on human bronchial epithelial culture [scRNA-Seq]

Project description:Purpose: To identify the cell types change and gene expression change under hypoxia on HBE cells. Methods: The primary human bronchial epithelial cells (HBE) were cultured on air-liquid interface (ALI) conditions. After 4 weeks, the cells were cultured under normoxic or hypoxic (1% O2) conditions for 6h or 5days. The cells were dissociated with Accutase solution and proceeded to scRNA-seq. Results: Hypoxia did not induce any hypoxia-specific cell types, however, all cell types upregulated hypoxia-related, and senescence-related genes and downregulated cell proliferation genes.

ncRNA (non-coding RNA) signature in endothelial cells during hypoxia

Project description:To define ncRNA expression in hypoxic endothelial cells, we applied pro-angiogenic hypoxia to cultured endothelial cells. Afterwards total RNA was isolated and underwent genechip analysis. HUVECs were subjected to normoxic or hypoxic (0.1-0.2% O2) cell culture conditions.

Effects of hypoxic preconditioning on neuroblastoma tumour oxygenation and metabolic signature in a chick embryo model

Project description:Hypoxia episodes and areas in tumours have been associated with metastatic dissemination and poor prognosis. Given the link between tumour tissue oxygen levels and cellular metabolic activity, we hypothesised that the metabolic profile between metastatic and non-metastatic tumours would reveal potential new biomarkers and signalling cues. We have used a previously established chick embryo model for neuroblastoma growth and metastasis, where the metastatic phenotype can be controlled by neuroblastoma cell hypoxic preconditioning (3 days at 1% O2). We measured, with fibre-optic oxygen sensors, the effects of the hypoxic preconditioning on the tumour oxygenation, within tumours formed by SK-N-AS cells on the chorioallantoic membrane (CAM) of chick embryos. We found that the difference between the metastatic and non-metastatic intratumoural oxygen levels was small (0.35% O2), with a mean below 1.5% O2 for most tumours. The metabolomic profiling, using NMR spectroscopy, of neuroblastoma cells cultured in normoxia or hypoxia for 3 days, and of the tumours formed by these cells showed that the effects of hypoxia in vitro did not compare with in vivo tumours. One notable difference was the high levels of the glycolytic end-products triggered by hypoxia in vitro, but not by hypoxia preconditioning in tumours, likely due to the very high basal levels of these metabolites in tumours compared with cells. In conclusion, we have identified high levels of ketones (3-hydroxybutyrate), lactate and phosphocholine in hypoxic preconditioned tumours, all known to fuel tumour growth, and we herein point to the poor relevance of in vitro metabolomic experiments for cancer research.

Project description:Comprehensive analysis of coding and non -coding transcriptome using ribo-depleted total RNA-seq and poly A selected RNA-seq of MCF-7 cells grown in hypoxia and normoxia. Breast cancer cell line (MCF-7) is cultured in normoxic condition (21% O2) and hypoxic condition (1%O2) for 24 hours. Expression of HIF-1alpha and/or HIF-2alpha subunits was suppressed using siRNAs in hypoxic MCF-7 cells. Total RNA was isolated from both hypoxia and normoxia conditions were subjected for ribosomal depleted stand specific RNA-seq and poly A selected RNA-seq

lncRNA expression profiles in OSCC cells cultured under normoxic and hypoxic conditions

Project description:Hypoxic microenvironment plays important roles in the progression of solid tumors including oral squamous cell carcinoma (OSCC). Long noncoding RNAs (lncRNAs) have gained much attention in the past few years. However, it is not clear whether lncRNAs could regulate hypoxia-adaptation of OSCC, and which lncRNAs participate in this process. Using an lncRNA microarray, we analyzed the aberrant lncRNA expression profiles in OSCC tissues compared with paired normal oral mucosa as well as in hypoxic OSCC cells compared with normoxic OSCC cells. Our microarray also identified 942 lncRNAs that were up-regulated and 507 lncRNAs that were down-regulated in cells cultured under hypoxia compared with those cultured under normoxia (Fold Change >= 2.0, P-value <= 0.05). An OSCC cell line Cal-27 was cultured under either 20% O2 (normoxic) or 1% O2 (hypoxic) conditions. Three samples from each group were obtained for microarray study.

Expression data from human SGBS adipocytes under hypoxic conditions

Project description:Hypoxia in adipose tissue is suggested to be involved in the development of a chronic mild inflammation, which in obesity can further lead to insulin-resistance. The effect of hypoxia on gene expression in adipocytes seems to play a central role in this inflammatory response observed in obesity. However, the global impact of hypoxia on transcriptional changes in human adipocytes is unclear. Therefore, we compared gene expression profiles of human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes under normoxic or hypoxic conditions to detect hypoxia-responsive genes in adipocytes by using whole human genome microarrays. Human SGBS adipocytes were cultured in a hypoxic environment (1% O2) for 3, 6 and 16 hours and the control group was cultured under normoxic conditions (21% O2). Total RNA was prepared from control and treated SGBS cells, in triplicate experiments, and probes were hybridized on ‘Human Genome U133 2.0’ arrays (Affymetrix).
