Identification of Nrf2-regulated genes in A549 lung cancer cells by oligonucleotide microarray

Project description:To elucidate the mechanisms by which Nrf2 regulates cell growth, we performed global gene expression profiling of A549 lung cancer cells with knockdown of Nrf2. Gene networks associated with carbohydrate metabolism and drug metabolism were significantly downregulated in Nrf2-depleted A549 cells. Gene Set Enrichment Analysis revealed significant enrichment of genes associated with carbohydrate catabolic processes, positive regulation of metabolic processes, PPP, and arachidonic acid metabolism. In summary, this analysis revealed that Nrf2 positively regulates transcription of genes that play key roles in central carbon metabolism. A549 cells were transfected with non targeting NS siRNA or siRNA targeting Nrf2. Mock transfected A549 cells were treated with transfection reagent alone. We had 3 biological replicates for each of the 3 groups. Ninty six hours post transfection, cells were lysed and total RNA was isolated.

Comparison of gene expression profiles of A549 cell treated with NRF2 siRNA and control siRNA

Project description:To examine the role of NRF2 in accelerating cell proliferation and to identify the target genes responsible for this function, transcriptome analysis was performed using A549 cells, in which NRF2 is constitutively activated. NRF2 was knocked down by siRNA against NRF2, and the gene expression profile was compared with that of A549 cells treated with control siRNA. To exclude off-target effects, three different siRNAs against NRF2 was independently applied. NRF2 siRNA or control siRNA was transfected into A549 cells. Cells were harvested 24 hours after transfection, and total RNA was purified.

Expression data from KEAP1 overexpression and NRF2 siRNA knockdown of A549 NSCLC cell

Project description:KEAP1 overexpressed and NRF2 siRNA knockdown A549 NSCLC cells were used to identify downstream genes of NRF2 pathway separately and by combinatorial analysis. We used triplicate microarrays of transfected A549 cells with mKeap1-GFP for overexpression, siRNAs targeting NRF2 for knockdown and siGFP as control respectively. As a result, we identified several genes which are involved in cancer metabolic functions in these cells. We used microarrays to identify the gene downregulated in both KEAP1 overexpressed and NRF2 siRNA knockdown A549 NSCLC cells and found a subset of downregulated genes which are involved in metabolic functions.

RNAseq analysis of A549 cells depleted of RPS19 using siRNAs

Project description:Gene expression profiling analysis of RNA-seq data for A549 cells transfected with non-targeting siRNA (siOTP) and KD derivatives (siRPS19) to ascertain relative gene expression (reads per kilobase per million, RPKM) for use to intersect with high-throughput RNA interference screening (siRNA) data to assess baseline expression of candidates being screened in these assays.

Comparison of the transcriptomic impact of NRF2 depletion with that of NUAK1 depletion in SW480 colorectal cancer cells

Project description:The intent of the experiment is to determine how much of NRF2 (NFE2L2)-dependent transcription requires NUAK1 upstream. SW480 cells were transfected with siRNA targeting either NRF2, NUAK1 or non-targeting control, and harvested for analysis by RNA-SEQ 48hrs after transfection. mRNA was analysed by Illumina paired-end RNA-SEQ

Gene expression profiling in lung and breast cancer cells treated by Bloom-specific siRNAs

Project description:A549 and MDA-MB-231 cells were transfected with the Bloom-specific siRNA. Total RNA was extracted using Trizol at 48 hours after transfection. RNA-SEQ was carried out to profile the gene expression in both culture conditions.

Pan-cancer transcriptomic analysis associates long non-coding RNAs with key mutational driver events

Project description:To identify genes regulated by NFE2L2 (Nrf2), we selected a lung cancer cell line (A549) in which NFE2L2 is normally active. Three transfections using siRNAs targeting NFE2L2 and four control transfections using two different negative control siRNAs were done. As a result, we found several genes up or down regulated in response to NFE2L2 inactivation in these cells. A549 cells were cultured, and 250,000 cells were transfected with Lipofectamine RNAiMAX reagent containing 5 nmol siRNA particles in a 6-well plate. Three transfections with siRNAs targeting NFE2L2 were performed, using three independent duplexes, while four control transfections were done using two different control duplexes, in addition to one mock (Lipofectamine only) transfection. RNA was prepared using the RNeasy Mini kit. 8 strand-specific total RNA-seq libraries were generated on an Illumina NextSeq 500. Between 50.5 and 60.6 million reads were obtained per sample. Reads were aligned to hg19 genome, at an alignment rate exceeding 94.4% for all samples.

Probing off-target effect of LMNA siRNA and pro-siRNA in HeLa-d1EGFP cell line

Project description:We have develped a novel method of making siRNAs (named pro-siRNA for prokaryotic siRNA). To evaluate off-targeting of pro-siRNA, we compared mRNA expression profile of HeLa-d1EGFP cells transfected with 4 nM LMNA siRNAs and pro-siRNAs by microarray.
