Project description:Analysis of human triple-negative breast cancer cells (TNBCs) which have high NF-kB activity. Proteins derived from NF-κB target genes might be molecular targets for cancer therapy. Results provide new insights into tumor proliferation mechanisms. Exp. 1: Mock MDA-MB-436 cells vs. MDA-MB-436 cells infected with Adenovirus-IkBaSR; Exp. 2: MDA-MB-436 cells infected with Adenovirus-GFP vs. MDA-MB-436 cells infected with Adenovirus-IkBaSR.
Project description:Indole-3-carbinol (I3C) is a natural anti-carcinogenic compound found at high concentrations in Brassica vegetables. ER-positive cell lines demonstrated the greatest sensitivity to the anti-tumor effects of I3C compared to ER-negative breast cancer cell lines. Gene expression analysis was performed to identify genes and pathways that accounted for sensitivity to I3C. Microarray analysis performed using Illumina HT-12 v4 expression arrays A total of 36 samples were analyzed with six breast cancer cell lines treated with either the vehicle control or the drug Indole-3-carbinol in triplicate. The cell lines were: MCF-7, T47D, ZR751(sensitive to the drug, apoptosis/growth arrest) and MDA-MB-231, MDA-MB-157, and MDA-MB-436 (insensitive to the drug). Sensitive cell lines are of the luminal subtype and insensitive cell lines are of the basal subtype.
Project description:Purpose:Assess the difference in gene expression of taxol-resistant TNBC cells relative to parental cells (MDA-MB-436 and HS 578t) Methods: RNA-seq was performed on paclitaxel-treated MDA-MB-436 cells that are resistant to Paclitaxel (R20A, R20B, R20C) and in control-treated (DMSO) parental MDA-MB-436 cells that are sensitive to Paclitaxel (DMSO) Results: We mapped about 20 million sequence reads per sample to the human genome (hg19) and identified identified differentially expressed genes Conclusions: Our study identified genes significantly enriched or repressed in taxol-resistant cells relative to parental cells in both TNBC models (MDA_MB-436 and HS 578T)
Project description:RNA-seq of MDA-MB-436 cells in control cells (shRen) and upon knockdown of MITF ( shQa, sh962) were generated by deep sequencing in duplicates
Project description:In order to identify the microRNAs differentially expressed according to the estrogen receptor status, total RNAs in triplicate from six breast cancer cell lines with different ERalpha status (ER+: T47D, BT-474, MDA-MB-483; ER-: MDA-MD-436, MDA-MB-231, MDA-MB-468) was extracted by using Trizol reagent and used for microarray experiments.
Project description:This series represents a set of experiments preformed using RNA isolated from human mammary epithelial cells, human MDA-MB-436 cells and HCC1954 cells. Keywords: parallel sample
Project description:We performed gene expression profiling on the MDA-MB-231 and MDA-MB-436 human breast cancer cell lines following siRNA-mediated inhibition of Fn14 expression as an approach to identify the mechanistic basis for Fn14 regulation of invasive capacity. Keywords: siRNA-mediated inhibition
