Effect of silencing of p53 on gene expression in MDA-MB 231 TNBC cell line. [sip53]

ABSTRACT: Mutant p53 can acquires oncogenic properties supporting tumor growth, metastases and chemoresistance, by reprogramming cancer cell transcriptome, proteome and metabolome. To investigate what is the gene expression network regulated by mutant p53, we silenced its expression in MDA-MB-231 Triple Negative Breast Cancer (TNBC) cell line. We then performed gene expression profiling analysis using data obtained from RNA-seq of MDA-MB 231.

Effect of silencing of p53 on gene expression in MDA-MB 231 TNBC cell line in medium with 100% and medium with 25% of amino acids. [aa]

Project description:Mutant p53 can acquires oncogenic properties supporting tumor growth, metastases and chemoresistance, by reprogramming cancer cell transcriptome, proteome and metabolome. To investigate what is the gene expression network regulated by mutant p53 in condition of limited amino acids availability, we silenced mutant p53 expression in MDA-MB-231 Triple Negative Breast Cancer (TNBC) cell line, grown in medium with 100% and medium with 25% of amino acids. We performed gene expression profiling analysis using data obtained from RNA-seq of MDA-MB 231.

lncRNA/mRNA expression profiling of miR-200c-overexpressing MDA-MB-231 cells

Project description:MiR-200c is a well-studied miRNA that is involved in stemness, the epithelial-mesenchymal transition, chemoresistance, radioresistance, and invasion/metastasis of various cancer cells. To obtain an overview of the lncRNA/mRNA regulated by miR-200c signaling in breast-cancer cell lines, we performed global lncRNA/mRNA-expression profiling on MDA-MB-231-pGIPZ and MDA-MB-231-miR-200c cells.

shRNAi profiling of human MDA-MB-231 cells expressing anti-p53 (shp53) short-hairpin RNAs treated with TFGbeta or control

Project description:TGFÎ² ligands act as tumor suppressors in early stage tumors but are paradoxically diverted into potent prometastatic factors in advanced cancers. The molecular nature of this switch remains enigmatic. We now show that TGFÎ²-dependent cell migration, invasion and metastasis are empowered by mutant-p53. To investigate the specific gene expression program by which mutant-p53 and TGFÎ² control invasion and metastasis in breast cancer cells, we compared the TGFÎ² transcriptomic profile of control and mutant-p53 depleted MDA-MB-231 cells. Experiment Overall Design: MDA-MB-231 cells, stably expressing either control (shGFP) or anti-p53 (shp53) short-hairpin RNAs, were left untreated or treated with TGFbeta. Samples were then processed for total RNA extraction and hybridization on Affymetrix microarrays. Four biological replicas (A, B, C, D) were used for each of the 4 conditions (1: untreated control; 2: TGFbeta treated control; 3: untreated p53-depleted cells; 4: TGFbeta treated mutant-p53-depleted cells), for a total of 16 samples.

The miRNA profiling in MDA-MB-231, MDA-MB-231/E1A and knockdown of Dicer in MDA-MB-231/E1A cells

Project description:Dicer, RNase III endonuclease, is an essential enzyme in miRNA biogenesis that regulates target gene expression, and it has been reported that aberrant expressions of Dicer associate with the clinical outcomes of patients in various cancers. To explore the miRNA differencial expression regulated by Dicer in MDA-MB-231/E1A cells, the microarray profiling analysis was employed to conduct differentially expressed miRNAs in stable MDA-MB-231/vector, MDA-MB-231/E1A, and MDA-MB-231/E1A/shDicer cells.

Impact of mutant p53 on TNF-induced gene expression

Project description:MDA-MB-231 are a metastatic triple-negative breast cancer cell line that bears a missense p53 mutation (R280K). We depleted endogenous mutp53 in MDA-MB-231 cells by siRNA transfection, and treated the cells with Tumor Necrosis Factor (TNF)-alpha. Microarray analysis was performed to evaluate the impact of mutant p53 on the transcriptional response triggered by TNFα in these cells. MDA-MB-231 cells transfected with control or p53 siRNA were treated with TNFα for 20 hrs or left untreated. The study comprises four experimental points, each in triplicate.
