Project description:Transcriptional profiling of breast cancer cells comparing pre-control transfected cells with cells transfected with pre-miR-125b. We searched for miR-125b targets by systematic screening of mRNA profiling of pre-miR-125b transfected MCF-7 cells and MDA-MB-435 cells. Two-condition experiment, pre-miR-125b Transfected vs. pre-control Transfected MCF-7 cells. One replicate per array.

Project description:Transcriptional profiling of breast cancer cells comparing LNA-control transfected cells with cells transfected with LNA-antimiR-21.We searched for miR-21 targets by systematic screening of mRNA profiling of LNA-antimiR-21 transfected MCF-7 cells and MDA-MB-231 cells. Two-condition experiment, LNA-antimiR-21 Transfected vs. LNA-control Transfected MCF-7 cells. One replicate per array.

Project description:In order to identify novel molecular targets associated with TNBC progression, we initially performed transcriptome analysis using RNA sequencing in breast cancer cell lines, classified as either the luminal subtype (MCF-7, T47D, ZR-75B) or basal-like subtype (MDA-MB-231, MDA-MB-435, Hs578T).
Project description:Human breast cancer cells MDA-MB-435 had higher metastatic potential and other aggressive characteristics than MCF-7 cells. Next-generation RNA sequencing (RNA-Seq) was used to clear this concern through comparison the transcriptomic expression profiles of these two cells.
Project description:Human breast cancer cells MDA-MB-435 had higher metastatic potential and other aggressive characteristics than MCF-7 cells. Next-generation RNA sequencing (RNA-Seq) was used to clear this concern through comparison the transcriptomic expression profiles of these two cells. Total RNA were extracted from MCF-7 and MDA-MB-435S cells, and the polyA+ mRNA was sequenced using Illumina Genome Analyzer IIx. The reads were mapped to RefSeq RNA reference sequences.
Project description:Expression of the transcription factor CEBPD is induced at early stages of the endoplasmic reticulum (ER) stress response. In order to identify the genes modulated by CEBPD during the ER stress response, we transiently silenced CEBPD expression in MDA-MB-435 melanoma cells and isolated mRNA at 6 h of treatment with Thapsigargin or DMSO control. As control, cells were transfected with two different control siRNA oligonucleotides. Results provide insights into which genes are modulated by CEBPD and/or Thapsigargin in MDA-MB-435 cell
Project description:The objective of this study was to determine the gene expression changes mediated by the alpha6beta4 integrin using MDA-MB-435 breast carcinoma cell line under normal culturing conditions (10% FCS in DMEM). Experiment Overall Design: Comparison of clones of MDA-MB-435 cells transfected with the integrin beta4 subunit (which results in cell surface expression of the integrin apha6beta4 integrin; clones 3A7 and 5B3) to those transfected with vector (mock; 6D2 and 6D7) only.
Project description:We report the use of single-cell RNA sequencing (scRNA-seq) technique to compare the transcriptomic profiles of human breast cancer cells with high and low expression of miR-125b. Methods: MDA-MB-231(miR-125b-promo-EGFP) cells were flow sorted at maximum and minimum 5% of miR-125b expression level, and deep sequenced using Illumina HiSeq 2000. The sequencing reads that passed quality filters were mapped to the reference genome using TopHat, followed by counting of reads numbers using HTSeq Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the human DNA reference genome (build hg19) and identified 48162 transcripts in MDA-MB-231(miR-125b-promo-EGFP) cells with low and high miR-125b expression. A total of 303 transcripts showed differential expression between low and high miR-125b expression cells, with |log2 (Fold change)| ≥ 2 and adjusted p value ≤ 0.05
