Spinophilin silencing in the breast cancer cell line SUM159

ABSTRACT: 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.

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 of shE4F1 or shCTRL SUM159 triple negative breast cancer cell line treated or not with Gemcitabine

Project description:E4F1 is a ubiquitously expressed zinc-finger protein of the Gli-Kruppel family that was first identified, more than 30 years ago, as a cellular target of the adenoviral oncoprotein E1A13S (Ad type V), required for transcriptional regulation of adenoviral genes. In this study we investigated the impact of direct translational target genes on DNA damage response induced by Gemcitabine. To do so, we performed RNAseq SUM159 triple negative breast cancer cell line. SUM159 was tranfected either with shE4F1 OR shscramble treated or not with Gemcitabine for 24 hours.

ChIP-seq of E4F1 in SUM159 triple negative breast cancer cell line

Project description:E4F1 is a ubiquitously expressed zinc-finger protein of the Gli-Kruppel family that was first identified, more than 30 years ago, as a cellular target of the adenoviral oncoprotein E1A13S (Ad type V), required for transcriptional regulation of adenoviral genes. In order to decipher E4F1 cellular target genes, we performed chromatin immunoprecipitation of endogenous E4F1 in SUM159 triple negative breast cancer cell line. Both input and immunoprecipitated DNA of two independant experiments were exhaustively sequenced and mapped on the human genome (hg38). Peak detection has been achieved with the HOMER suite algorithms.

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)

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.

Transcriptomes of triple-negative breast cancer (TNBC) cells (SUM159) and non-TNBC cells (HCC1569) that overexpressed JMJD6 were compared

Project description:The expression levels of JMJD6 and its correlation with H2A.XY39ph differed in TNBC and non-TNBC cells. In addition, we have previously shown that H2A.XY39ph levels are positively correlated with tumor size, histological grade and advanced TNM stage in breast cancer. To analyze the role of JMJD6 in regulating the characteristics of different subtypes of breast cancer, the transcriptomes of TNBC cells (SUM159) and non-TNBC cells (HCC1569) that overexpressed JMJD6 were compared. We speculate that JMJD6 overexpression cause autophagy pathway activation in TNBC via enhancing ATG genes expression.

Transcriptome profiling of SUM159 and derivatives with different metastasis capability

Project description:Triple negative breast cancer cell line SUM159 labeled with triple reporter (TR, TK-GFP-fLUC) injected into Nude mice via mammary fat pad and tail vein injection. Tumor progression is monitored by in vivo bioluminescent imaging. Tumors from mammary and lung were isolated and cultured. These derivatives cells are further tested for their capability to develop mammary primary tumor and metastasis in lung and bone in mice. The total RNA samples are extracted from the panel of SUM159 and derivatives and the transcriptome profiles are determined by microarray. The correlation of transcriptome of the cells to metastasis capability indicated candidate genes and regulatory pathways of metastasis of TNBC.
