High-throughout sequencing of ovarian cancer cells treated with TMPyP4 and H2O2

Project description:The high-throughput sequencing technology was performed after the treatment of human ovarian cancer cells A2780 with TMPyP4 and H2O2 purchased from Sigma-Aldrich, to explore the expression of genes related to cell proliferation, DNA damage and ROS levels of ovarian cancer cells A2780 after the treatment of TMPyP4 and H2O2, and to find an interesting target pathway,HIF-1 signaling pathway.

RNA sequencing of hydrogen peroxide (H2O2)-treated melanocytes

Project description:Purpose: Determine the mechanism of H2O2-induced signaling in melanocytes. Method: Primary human epidermal melanocytes were treated with H2O2 (200 μM) and incubated for 24 h. Total RNA (500 ng) from melanocytes were extracted and subjected to library synthesis. Results: H2O2-treated melanocytes exhibited upregulation of cell death and type 1 interferon-related genes. Conclusion: H2O2-induced melanocyte signaling was well evaluated using RNA sequencing.

Human SW480 cells: Untreated vs H2O2 Treated

Project description:ChIP-on-chip tilling array comparing untreated human SW480 cells vs SW480 cells treated with 2mM H2O2 for 30min. Exposing cells to the reactive oxygen species, hydrogen peroxide, recruits DNA methyltransferase 1 (DNMT1) to damaged chromatin. DNMT1 becomes part of a complex(es) containing DNMT3B and members of Polycomb Repressive Complex 4. The goal was to determine the effect of hydrogen peroxide treatment on chromatin, including changes in histone modifications and binding patterns of chromatin-associated proteins. [Agilent-014706]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and EZH2. [Agilent-014707]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and EZH2. [Agilent-026595]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and H3. [Agilent-027811]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Four-mark: H3, 3MeK4H3, AcK16H4, and 3MeK27H3.

Expression profiling of small RNAs in control and H2O2-treated rice seedlings

Project description:We aimed to identify putative H2O2-regulated miRNAs expressed in rice seedlings under oxidative stress by using a deep sequencing approach developed by Solexa (Illumina). Two small RNA libraries were constructed from H2O2-treated and control rice seedlings, and more than five million small RNA sequence reads were generated for each library. We identified seven H2O2-responsive miRNA families via expression profiling of the miRNAs based on a comparative miRNAomic analysis in combination with experimental validation. Furthermore, 32 miRNAs, 17 from known miRNA loci and 15 from novel miRNA loci, were also newly identified from the sequencing data. To the best of our knowledge, this is the first report of a systematic investigation of H2O2-regulated miRNAs and their targets in plants.

Whole Transcriptome Sequencing (mRNA-seq) of cultured pulmonary primary endothelial cells treated with or without H2O2

Project description:ROS once released from myeloid cells is quickly converted into H2O2 in lungs. We performed RNAseq of cultured pulmonary primary endothelial cells treated with or without H2O2. Pathway enrichment analysis revealed that some of the signaling pathways that are altered by H2O2 are related to AKT signaling. AKT signaling has a protective role in a murine model of ALI by preventing capillary leakage. Moreover, H2O2 stimulates AKT activation in endothelial cells to strengthen vessel barrier integrity

Methylation profile generated by reduced representation bisulfite sequencing (RRBS) of H2O2-treated and untreated HCT116 cells

Project description:DNA methylation is an important regulatory mechanism that contributes to transcriptional repression. To examine whether DNA methylation affects the transcriptional changes of DNA repair genes under H2O2-induced oxidative stress, we performed reduced representation bisulfite sequencing (RRBS) in H2O2-treated and untreated HCT116 cells.
