Project description:We performed paired-end poly A+ RNA sequencing using total RNA isolated from serum-starved and serum-released (6-hour) control and MIR222HG-depleted WI-38 cells
Project description:We report gene expression data from total RNA-seq of HCT116 human colon carcinoma cells treated with siRNA against PFDN2 and PFDN5 (both part of a complex known as prefoldin). Cells were independently treated with one of the previously mentioned siRNAs or with an exogenous control siRNA (luciferase GL2). All cells were treated with the different siRNAs for 24 hours, then serum-starved them for 48 hours, and finally stimulated by adding serum for 90 minutes. Samples were taken before and after serum stimulation. Prefoldin depletion provoked transcriptional alterations across the genome of human cells. Severe pre-mRNA splicing defects were also detected, particularly under serum stimulation conditions. We found a significant impairment of co-transcriptional splicing during transcription elongation.
Project description:To identify genes specifically activated by deregulated E2F, we examined gene expression profiles using human normal fibroblasts (HFFs), which were starved of serum and re-stimulated with serum, over-expressed with E2F1 or expressed with adenovirus E1a to forcedly inactivate RB. To identify genes activated by growth stimulation, human normal fibroblasts (HFFs) were starved of serum for 48 hr, infected with control virus, restimulated with serum or left serum-starved for 18 hr and harvested. To identify genes actived by deregulated E2F, HFFs were starved of serum for 48 hr, infected with control virus, adenovirus expressing E2F1 or adenovirus E1a, further cultured in the absence of serum for 18 hr and harvested. Gene expression profiles of ecach sample were examined by DNA microarray.
Project description:The study aimed to identify the differentially regulated microRNAs during serum starvation. We identified miRNAs exhibiting altered expression in asynchronous, serum starved and serum re-supplemented human cells. We identified several miRNAs that were upregulated following serum starvation and downregulated upon serum re-supplementation.
Project description:We used microarrays to profile gene expression changes following growth factor stimulation of primary human fibroblasts. We serum starved (0.1% serum) fibroblasts for 48 hrs and restimulated with 10% serum for 0, 2, 4, 6 and 8 hrs. Total RNA was extracted from 2 independent biological replicas for each time point and hybridized to expression arrays.
Project description:Cells were serum-starved with 0.1mM glucose (1mM pyruvate) for 24 h. The glucose was withdrawn (basal) or increased to 2.5 mM for 3 h. Raw data set 1-3 is basal, 4-6 glucose stimulation
