Project description:Whilst the biological function of many lncRNAs remains unknown, recent evidence has suggested that lncRNAs may be important regulators of cellular growth, differentiation and may play a significant role in cancer. Epidermal growth factor (EGF) an activator of the ERK1/2 signalling cascade is an important spatio-temporal regulator of transcription and, ultimately, of cellular growth and movement. In order to identify lncRNAs regulated by EGF signalling, we sequenced nuclear RNA in the presence or absence of EGF stimulation.
Project description:Results of growing MCF10A cells continuously in serum free media supplemented with EGF (MCF10A) or AREG (MCF10A+AREG) followed by 24 hours of ligand withdrawl and measuring gene expression provides information as to what genes are regulated by AREG and EGF in a normal mammary epithelial cell model
Project description:Results of growing MCF10A cells continuously in serum free media supplemented with EGF (MCF10A) or AREG (MCF10A+AREG) followed by 24 hours of ligand withdrawl and measuring gene expression provides information as to what genes are regulated by AREG and EGF in a normal mammary epithelial cell model MCF10A cells continuously in serum free media supplemented with 10ng/ml of EGF (MCF10A) or 20ng/ml of AREG (MCF10A+AREG) followed by 24 hours of ligand withdrawl. Total RNA was collected and genome-wide analysis of expression was performed on RNA from each cell line.
Project description:MCF10A cells derived from spontaneously immortalized normal human mammary epithel were subjected to EGF/SERUM stimulation for 0,20,40,60,120,240 and 480 minutes. We used microarrays to understand the temporal regulation of the cellular EGFR cascade. Keywords: time course
Project description:Expression data from ERBB2 over-expression and EGF stimulation in MCF10A cells The cells were transduced with retroviruses encoding vector control (pBabe) or pBabe-ErbB2. After infection cells were switched to assay medium supplemented with only 2% horse serum and no EGF. For EGF stimulation, cells transduced with empty vector were treated with EGF at 50 ng/ml for 2 hours before harvesting.
Project description:This SuperSeries is composed of the following subset Series:; GSE6783: Expression data from HELA cells subject to EGF stimulation; GSE6784: Expression data from MCF10A cells subject to EGF stimulation Experiment Overall Design: Refer to individual Series
Project description:Using basal‐like untransformed cells, MCF10A, as a model system, data from our laboratory showed that both mRNAs and microRNAs exhibit dynamic changes in expression following EGF stimulation (Amit et al, 2007; Avraham et al, 2010; Kostler et al, 2013). We further demonstrated that the inducible mRNAs and microRNAs are embedded into regulatory subnetworks, which are deregulated in diverse tumor types. Considering the emerging roles for long noncoding RNAs (lncRNAs) in metastasis of breast cancer (Serviss et al, 2014), we raised the possibility that some EGF‐inducible lncRNAs might play a role in basal‐like breast cancer. Thus, MCF10A cells were stimulated with EGF (10 ng/ml) for 0, 20, 40, 60, 120, 240 and 480 minutes. RNA was then extracted from cells and expression of lncRNAs was measured using Agilent SurePrint microarrays.
Project description:Mammary epithelial cells MCF10A and HER2 overexpressing MCF10A cells were grown on matrigel in the absence or presence of epidermal growth factor. Cells were lysed and RNA was collected at 1.5,3,5,7,9 days. Total 20 arrays from four time course experiments. MCF10A and MCF10A-HER2 (overexpressed HER2) were plated on Matrigel in the absence or presence of 20 ng/ml of EGF. This design creates four panels of experiments of 5 time points each.
