Project description:To identify gene expression changes associated with overexpression of miR-105 or MYC in MCF10A non-cancerous human mammary epithelial cells, we analyzed RNA isolated from engineered MCF10A cell lines that stably express empty vector, GFP, miR-105, or MYC by RNA-seq. Gene expression in cells overexpressing miR-105 or MYC was compared to cells expressing the empty vector or GFP, both of which served as controls in this experiment.
Project description:The multifunctional protein tyrosine phosphatase PRL-1 (Gene Symbol: PTP4A1) has been identified as an important oncogene with roles in promoting cell proliferation, survival, migration, invasion, and metastasis. However, little is currently known about the signaling pathways through which it mediates its effects. We used Affymetrix Human Genome U133 Plus 2.0 arrays to examine the global molecular changes of gene expression occurring in response to stable PRL-1 overexpression in human embryonic kidney 293 (HEK293) cells. Total RNA was extracted from triplicate cultures of HEK293 cells stably overexpressing PRL-1 (HEK293-PRL-1) and HEK293 cells stably transfected with empty pcDNA4 vector (HEK293-Vector). Samples were hybridized to Affymetrix HG U133 Plus 2.0 microarrays (1 array per sample for a total of 6 arrays). One of the arrays hybridized with a PRL-1 transfected sample was excluded after qRT-PCR demonstrated that this sample did not exhibit increased PRL-1 expression over the level of the empty vector controls. The remaining 2 HEK293-PRL-1 samples both expressed PRL-1 at least 2-fold higher than any of the 3 empty vector controls.
Project description:In order to understand what genes were regulated by the presence of a new fusion transcript (LMO3-BORCS5), we stably transfected either an empty vector (pc3.1) or vector containing LMO3-BORCS5 sequence into A673 human Ewing sarcoma cell line. 2 different clones were obtained for each condition (4 conditions total), and 4 different RNA extractions were performed for each clone (4 x 4 = 16 conditions total).
Project description:Transcriptome profiling of Human OCI-AML3 cell line with low RhoH expression, stably transfected either by Empty or by RhoH sur-expressing vectors.
Project description:To identify gene expression changes associated with treatment of EV that carry high levels of miR-105 (from MDA-MB-231 and MCF10A/miR-105 cells) in human breast tumor derived CAF, we analyzed RNA isolated from PBS- or EV-treated CAF. Gene expression in CAF treated with EV from MDA-MB-231 or MCF10A/miR-105 cells was compared to cells treated with PBS or EV from MCF10A cells, both of which served as controls in this experiment.
Project description:To elucidate the molecular mechanism and signaling pathways that PinX1 is involved in, a Human LncRNA Array V2.0 (Arraystar, USA)-based genome wide screen of the alterations in lncRNA and mRNA expression profiles was performed in MCF-7 cells stably overexpressing PinX1. MCF-7 breast cancer cells were transfected with the pcDNA3.1-PinX1 and pcDNA3.1 empty vector and the microarray analysis were performed after the clonal selection of cells with a high expression level.
