Project description:We observed gene expression difference between different groups after MDA-MB-231 treated with DMSO, 10 μM DAC, 1 μM DEX, or DAC+DEX. Data obtained from high-throughput sequencing (Illumina NovaSeq 6000 platform) were transformed into raw sequenced reads by CASAVA base calling and stored in FASTQ format. Gene expression of each groups are listed in raw data files. Some different expression genes between two groups are further validated with qRT-PCR.
Project description:4-Hydroxynonenal (HNE), a cytotoxic and diffusible electrophile generated by the spontaneous decomposition of oxidized lipids, has a suspected role in neurodegenerative and inflammatory disease processes. In addition to promoting cell death, elevated levels of HNE lead to the engagement of cytoprotective signaling pathways, including the heat shock, antioxidant, DNA damage, and ER stress responses. Activation of the heat shock response, mediated by the transcription factor heat shock factor 1 (HSF1), is critical for maintaining cellular viability in the presence of HNE. Accordingly, silencing HSF1 expression using siRNA enhances the toxicity of HNE. Microarray analysis of samples from control and HSF1-silenced cells was performed to investigate which associated changes in gene could be responsible for the decrease in cellular viability. Four different experimental conditions were investigated. Samples were prepared and analyzed in triplicate. Samples 1-3 received NEG control siRNA and DMSO (vehicle) for 6 h. Samples 4-6 received NEG control siRNA and 50 uM HNE for 6 h. Samples 7-9 received HSF1 siRNA and DMSO (vehicle) for 6 h. Samples 10-12 received HSF1 siRNA and 50 uM HNE for 6 h.

Project description:Genome-wide DNA Methylation Data from Illumina HumanMethylationEPIC arrays for whole blood samples from 570 healthy individuals. Raw IDAT files are available for a subset of 403 samples on EGA. Raw data (IDAT files) and associated phenotype information are available for all individuals included in this study (n=570) directly from CIBMTR. Data are available under controlled access release upon reasonable request and execution of a data use agreement. Requests should be submitted to CIBMTR at info-request@mcw.edu and include the study reference IB17-04.
