View SamplesWe probed the mechanism of cross-regulation of osmotic and heat stress responses by characterizing the effects of high osmolarity (0.3M vs. 0.0M NaCl) and temperature (43oC vs. 30oC) on the transcriptome of Escherichia coli K12 using E. coli Genome 2 Array (Affymetrix, Inc.). Independent array hybridizations were carried out for 3 biological replicates (independent cultures). Total RNA was extracted using a hot phenol-chloroform method. cDNA synthesis, fragmentation and labeling, and washing and scanning of E. coli GeneChip Arrays were performed according to the instructions of the manufacturer (Affymetrix Technical Manual, Affymetrix, Inc., USA). Labeled cDNA was hybridized to E. coli Genome 2 Array (Affymetrix, Inc.). Independent array hybridizations were carried out for 3 biological replicates (independent cultures) of each condition. A number of genes in the SoxRS and OxyR oxidative stress regulons were up-regulated by high osmolarity, high temperature, and/or by the combination of both stresses. This result could account for cross-protection of osmotic stress against oxidative stress. The trehalose biosynthetic genes were induced by both stresses, in accord with the proposed protective role of this disaccharide against thermal and oxidative damage.

PDEF promotes luminal differentiation and acts as a survival factor for ER-positive breast cancer cells.
Cell line, Treatment
View SamplesRecent studies suggest that PDEF is required for secretory cell differentiation in several epithelial tissues. To investigate PDEF in the mammary gland, we examined the effect of this transcription factor on gene expression using microarray based profiling of MCF-10A cells. These cells are non-transformed mammary epithelial cells that express protein and gene expression programs of basal epithelial cells and undetectable levels of endogenous PDEF. Bioinformatics analysis of the genes induced or repressed by PDEF overexpression in MCF10A cells revealed a striking effect on expression of luminal and myoepithelial cell markers.

View SamplesMicroarray gene expression analysis was performed in MCF7 cells transduced with a non-specific shRNA or PDEF-targeting shRNA, and both subjected to hormone depletion for 48 hours. Analyses of differentially expressed genes combined with gene ontology revealed a downregulation of cell cycle related-genes and an upregulation of apoptosis-related genes in PDEF knockdown cells. These target genes constitute potential effectors of the pro-survival role of PDEF.
