The Role of EGR1 in hypoxia/reoxygenation (H/R) injuried mice primary renal tubular epithelial cells

Project description:The Role of EGR1 in hypoxia/reoxygenation (H/R) injuried mice primary renal tubular epithelial cells Purpose: we performed comparative RNA-seq analyses to identify differentially expressed genes between Knockdown of Egr1 and negtive control in hypoxia/reoxygenation (H/R) injuried mice primary renal tubular epithelial cells. Methods:we grew mouse primary renal tubular epithelial cells to approximately 50% confluence, transfected using EndoFectin™ Max (GeneCopoeia, China). H/R was used to mimic IRI in vitro. Briefly, cells were incubated in glucose-free medium in a tri-gas incubator (94% N2, 5% CO2 and 1.0% O2) at 37 °C for 6 hours. Subsequently, cells were incubated in complete medium under normal conditions for 18 hours for reoxygenation. Cells were then collected by 1ml TRIzol (Invitrogen, Carlsbad), and sent to Annoroad Corporation (Beijing, China) for high throughout Illumina NovaSeq 6000 sequencing (GPL24247) (Illumina, San Diego, CA, USA). Results: To determine the possible pathways and downregulated genes of Egr1 in protecting mice primary renal tubular epithelial cells from injury, we conduct the transcriptomotic sequencing. After sequence, the clean reads rate of all samples were ≥98%.The quality of the assembled transcriptome is good enough for functional annotation and further analysis. Conclusions: We performed RNA-sequencing (RNA-Seq) on isolated mouse renal tubular epithelial cells of 3 groups, negtive control(Sham group) treated with H/R (H/R group) or Egr1 overexpression plasmid (Egr1OV group). Egr1-responsive genes showed significant enrichment in proliferation pathway.

The Role of SOX9 in hypoxia/reoxygenation (H/R) injuried mice primary renal tubular epithelial cells

Project description:The Role of SOX9 in hypoxia/reoxygenation (H/R) injuried mice primary renal tubular epithelial cells Purpose: we performed comparative RNA-seq analyses to identify differentially expressed genes between Knockdown of Sox9 and negtive control in hypoxia/reoxygenation (H/R) injuried mice primary renal tubular epithelial cells. Methods:we grew mouse primary renal tubular epithelial cells to approximately 50% confluence, transfected using EndoFectin™ Max (GeneCopoeia, China) 12h before suffering to H/R injury. H/R was used to mimic IRI in vitro. Briefly, cells were incubated in glucose-free medium in a tri-gas incubator (94% N2, 5% CO2 and 1.0% O2) at 37 °C for 6 hours. Subsequently, cells were incubated in complete medium under normal conditions for 18 hours for reoxygenation. Cells were then collected by 1ml TRIzol (Invitrogen, Carlsbad), and sent to Annoroad Corporation (Beijing, China) for high throughout Illumina NovaSeq 6000 sequencing (GPL24247) (Illumina, San Diego, CA, USA). Results: To determine the possible pathways of Sox9 in protecting mice primary renal tubular epithelial cells from injury, we conduct the transcriptomotic sequencing. After sequence, the clean reads rate of all samples were ≥98%.The quality of the assembled transcriptome is good enough for functional annotation and further analysis. Conclusions: We performed RNA-sequencing (RNA-Seq) on isolated mouse renal tubular epithelial cells of two groups, treated with H/R and transfected with siNC (H/R+siNC group) or siSox9 (H/R+siSox9 group). SOX9-responsive genes showed significant enrichment of the WNT signaling pathway in primary tubular epithelial cells.

Gene expression profiling in MCF7 cell lines under hypoxia and reoxygenation

Project description:Purpose: Study hypoxia and reoxygenation induced changes in genome-wide gene expression Methods: Using the MCF7 breast epithelial adenocarcinoma cell line as a model, we studied epigenomic reprogramming as a function of fluctuating oxygen tension. To this end, we performed a transcriptomics analysis in MCF7 cells subjected to changes in oxygenation (i.e. acute hypoxia, chronic hypoxia, reoxygenation). Results: Global downregulation upon hypoxia; partial restore on reoxygenation. Conclusions: Our data show that oxygen availability dynamically regulates gene transcription.

lncRNA SCIRT in hypoxia/reoxygenation.

Project description:To know effects of long noncoding RNA (lncRNA) SCIRT in hypoxia/reoxygenation (H/R). We compared expression profiles of human umbilical vein endothelial cells (HUVECs) under normal condition, H/R condition without SCIRT knockdown, and H/R condition with SCIRT knockdown.

H3K4me3 and H3K27me3 ChIP-seq profiling in MCF7 cell lines under hypoxia and reoxygenation

Project description:Purpose: Study hypoxia and reoxygenation induced changes in genome-wide H3K4me3 and H3K27me3 occupancy Methods: Using the MCF7 breast epithelial adenocarcinoma cell line as a model, we studied epigenomic reprogramming as a function of fluctuating oxygen tension. To this end, we combined chromatin-immunoprecipitation and deep-sequencing analysis to identify H3K4me3-marks and H3K27me3-marks in MCF7 cells subjected to changes in oxygenation (i.e. acute hypoxia, chronic hypoxia, reoxygenation). Results: H3K4me3 and H3K27me3-marks showed a rapid global increase at specific sites throughout the genome under hypoxia, both genic and inter-genic, that was partly restored upon reoxygenation. Conclusions: Our data show that oxygen availability dynamically regulates the epigenetic state of the genome.
