Transcription profiling by microarray of lncRNA affected by EGF stimulation of MCF10A cells


ABSTRACT: 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.

Long noncoding RNAs (lncRNAs) are emerging as regulators of gene expression in pathogenesis, including cancer. Recently, lncRNAs have been implicated in progression of specific subtypes of breast cancer. One aggressive, basal-like subtype associates with increased EGFR signaling, while another, the HER2-enriched subtype, engages a kin of EGFR Based on the premise that EGFR-regulated lncRNAs might control the aggressiveness of basal-like tumors, we identified multiple EGFR-inducible lncRNAs in ba  ...[more]
