TranscriptomicsTranscription profiling of E. coli grown on mixture of glucose and lactose in a time series
Time series analysis of glucose-lactose diauxie; When cultured on a mixture of glucose and lactose, E. coli grows preferentially on glucose until it is exhausted, resulting in growth arrest while the cells adjust to growth on lactose, i.e., diauxie.

TranscriptomicsVibrio cholerae N16961 overexpression of CpxR
Transcriptionnal profiling comparing a V. Choleare M-bM-^HM-^FcpxR mutant harboring either (pBAD33-cpxR) or empty (pBAD33) grown for 1h under inducing conditions. Two independent experiments with a technical replicate for each.

TranscriptomicsDNA methylation in Arabidopsis thaliana
DNA methylation in wild type bolting plants, wild type seedlings, and ddm1 seedlings. The purpose of the McrBC methylation microarray assay is to determine which regions of a genome are methylated versus those that are unmethylated in a single Arabidopsis thanliana genotype. McrBC is a methylation-s...

TranscriptomicsMicroarray study of the Sex Inducer Proteins in Cryptococcus neoformans var. neoformans (JEC20/21)
To identify genes regulated by the homeodomain transcription factors Sxi1M-NM-1 and Sxi2a (Sex Inducer 1M-NM-1 and 2a) in Cryptococcus neoformans, we carried out a whole-genome expression experiment. We performed two independent whole-genome microarray experiments comparing transcript levels in cell...

TranscriptomicsCG methylated microarrays identify novel methylated sequence bound by the CEBPB|ATF4 heterodimer that are active in vivo
To evaluate the effect of CG methylation on DNA binding of sequence-specific B-ZIP transcription factors (TFs) in a high-throughput manner, we enzymatically methylated the cytosine in the CG dinucleotide on protein binding microarrays. Two Agilent DNA array designs were used. One contained 40,000 ...

TranscriptomicsmRNA levels in Wild-type versus ddm1 Arabidopsis thaliana
mRNA levels in Wild-type versus ddm1 Arabidopsis thaliana seedlings and bolting plants. Features found to be significantly enriched for DNA methylation were determined. This SuperSeries is composed of the following subset Series: GSE1324: EV23+24 mRNA levels in Wild-type versus ddm1/+ backcross bo...

TranscriptomicsDysregulated microRNAs in sapje and sapje-like zebrafish
MicroRNAs were isolated from wild type (SW and SLW; sapje-wild type littermates, sapje-like-wild type littermates) and sapje and sapje-like fish at 5 and 30 days post fertilization (dpf) Comparison of wildtype and sapje and sapje-like fish at 5 and 30 dpf to identify commonly dysregulated microRNA b...

TranscriptomicsPost-weaning selenium and folate supplementation affects gene and protein expression and global DNA methylation in mice fed high-fat diets
Background: Consumption of high fat diets has negative impacts on health and well-being, some of which may be epigenetically regulated. Selenium and folate are two compounds which influence epigenetic mechanisms. We investigated the hypothesis that post-weaning supplementation with adequate levels o...

TranscriptomicsChIP-chip analysis of CspC binding in Salmonella enterica serovar Typhimurium strain SL1344
We performed Chromatin Immunoprecipitation (ChIP) and microarray hybridization analysis of CspC binding in Salmonella Typhimurium strain SL1344 which has been genetically engineered to express a 3xFLAG tagged CspC protein. Chromatin samples were prepared from SL1344 CspC 3xFLAG grown to exponential ...
