Spinophilin silencing in the breast cancer cell line SUM159

Project description:Microarray profiling was used to determine the most abundantly expressed genes in spinophilin-silenced breast cancer cells compared to control cells in the cell line SUM159. We identified several differentially expressed genes in spinophilin-silenced cells. A total number of six samples were analyzed, each in three replicates. There are three SUM159 Control samples and three samples of the cell line SUM159 with silenced spinophilin.

RNA-Seq analysis of SUM159 DAPK3 knockout (KO) cells and control cells

Project description:We conducted RNA sequencing of SUM159 DAPK3 KO and control cells followed by Gene Set Enrichment Analysis (GSEA) to identify altered gene expression pathways by DAPK3 knockout. Epithelial-mesenchymal transition (EMT) pathway was the top significantly down-regulated pathway in SUM159 DAPK3 KO cells as compared to control cells.

Gene expression profiling of transmitochondrial cybrids (triple negative breast cancer cells in SUM159 background)

Project description:We used a transmitochondrial cybrid (cybrids)-based discovery approach to identify mitochondria-regulated cancer pathways in TN BCa. Cybrids were generated under a moderately metastatic TN BCa cell line SUM159 as the common nuclear background with mitochondria from benign breast epithelium (A1N4) and moderately metastatic (SUM159) TN BCa cells. In vitro and in vivo studies suggested that even under the common moderately cancerous nuclear background, mitochondria from benign cells inhibit and metastatic cell induce cancer properties of a moderately aggressive TN BCa cell. Gene expression studies identified c-Src onco-pathway as one of the major cancer pathways altered according to the mitochondria status of the cybrids. SUM159 Ï0 cells were used as nuclear donor and A1N4 and SUM 159 cells were used as mitochondrial donor cells. The two groups were profiled for gene expression using microarrays. two group comparison (159/SUM159 vs A1/SUM159)

Expression data from TGFBR3 controls and TGFBR3 knockdown of SUM159 3D cultures

Project description:The objective of this experiment was to determine global gene expression change in triple negative cell line upon knockdown of TGFBR3. Genotype specific differences in expression profiles have been evaluated using human HuGene1.0-ST affymetrix array. RNA was extracted from SUM159 controls and SUM159 TGFBR3KD cells cultured in 3-dimensional in vitro system.

Effect of targeting NOS2 on gene expression of triple-negative breast cancer (metaplastic) SUM159 cell lines

Project description:To investigate the role of iNOS in tumor cell morphology and gene expression, we utilized CRISPR-Cas9 gene editing (NOS2 Double Nickase Plasmid, Santa Cruz) to knockout NOS2 in SUM159 cells. After puromycin selection, resistant clones were selected by immunoblotting for iNOS expression and nitrite/nitrate colorimetric assay. We then performed gene expression profiling analysis using data obtained from RNA-seq of parental SUM159 cells compared to NOS2KO SUM159 cells.

Transcription profiling by array of cells starved of leucine in the presence or absence of a dominant negative HSF1 mutant (dnHSF1, HSF379).

Project description:Cells were starved for leucine in the presence or absence of a dominant negative HSF1 mutant (dnHSF1, HSF379). Changes in transcriptome relative to cells cultured with leucine were determined. The experiment shows the effect of dnHSF on the amino acid starvation response.
