SHARP1 suppresses breast cancer metastasis by promoting degradation of hypoxia-inducible factors

Project description:Triple Negative Breast cancer accounts for some of the most aggressive types of breast cancer. By interrogating clinical datasets, we found that the activities of p63 and Hypoxia-Inducible-Factors (HIFs), two master regulators of the invasive and metastatic cancer cell phenotype are linked in TNBC through the p63-target Sharp1. Mechanistically, Sharp1 promotes HIF-1Î±/HIF-2Î± proteasomal degradation by serving as HIFs presenting factor to the proteasome independently from oxygen levels and prior ubiquitination. To investigate unbiasedly if Sharp1 is a general inhibitor of HIF induced transcriptional program, we compared the transcriptomic profile of cells either overexpressing Sharp1 or depleted of HIF1a and HIF2a. We collected RNA from control MDA-MB-231 cells (shGFP) or MDA-MB-231 cells overexpressing Sharp1 or MDA-MB-231 cells depleted of HIF1a and HIF2a (shHIF). Cells were left untreated in normal culturing conditions before harvesting. 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: shGFP, control cells; 2: shHIF cells; 3: Sharp1-overexpressing cells) for a total of 12 samples.

Tang2019 - Pharmacology modelling of AURKB and ZAK interaction in TNBC

Project description:Aurora Kinase B and ZAK interaction model Equivalent of the stochastic model used in "Network pharmacology model predicts combined Aurora B and ZAK inhibition in MDA-MB-231 breast cancer cells" by Tang et. al. 2018. The only difference is cell division and partitioning of the components, which are available in the original model for SGNS2.

Gene expression profile in breast cancer cells

Project description:We report the gene expression patterns in MDA-MB-231 (a line selected for low metastatic ability), MDA-MB-231-1833 (its bone-tropic metastatic derivative line), MDA-MB-231p27CK-DD (a phosphomimetic cell line), MDA-MB-231-1833shp27 (p27 knockdown cell line), MDA-MB-231-1833PF1502 (PI3K inhibitor treatment). It shows that the gene expression pattern are regulated in a p27 phosphorylation-dependent manner.

LncRNA Uc003xsl.1 Activates of NF-κB/IL8 Axis to Promotes Triple-negative Breast Cancer Progression via A Decoy Role to NKRF [lnc231]

Project description:To discover the potential drivers of TNBC metastasis, we established an in vivo model by injecting MDA-MB-231cells into the tail veins of mice. Then, the breast tumor cells that successfully grew into metastatic lung tumors were collected and expanded in vitro, followed by re-injected into the tail veins of mice for lung metastasis. After three rounds of selection, a highly metastatic subline, MDA-MB-231-P3, was established, and more frequent micro-metastasis was detected in MDA-MB-231-P3 groups than that of MDA-MB-231 groups when the lungs of mice were stained with hematoxylin and eosin (HE). The lncRNA profiles of MDA-MB-231 or MDA-MB-231-P3 cells were analyzed by lncRNA sequencing. A total of 267 lncRNAs in MDA-MB-231-P3 cells were upregulated more than 2-fold in comparison to the MDA-MB-231 cells.

Metabolic and lipidomic characterization of radioresistant MDA-MB-231 human breast cancer cells to investigate potential therapeutic targets

Project description:To provide preliminary insights into metabolic and lipidomic characteristics in radioresistant triple-negative breast cancer (TNBC) cells and suggest potential therapeutic targets, we performed a comprehensive metabolic and lipidomic profiling of radioresistant MDA-MB-231 (MDA-MB-231/RR) TNBC cells and their parental cells using gas chromatography-mass spectrometry and nano electrospray ionization-mass spectrometry, followed by multivariate statistical analysis. Buthionine sulfoximine (BSO) and radiation were co-treated to radioresistant TNBC cells. The level of glutathione (GSH) was significantly increased, and the levels of GSH synthesis-related metabolites, such as cysteine, glycine, and glutamine were also increased in MDA-MB-231/RR cells. In contrast, the level of lactic acid was significantly reduced. In addition, reactive oxygen species (ROS) level was decreased in MDA-MB-231/RR cells. In the lipidomic profiles of MDA-MB-231/RR cells, the levels of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were significantly increased, whereas those of most of the phosphatidylinositol species were significantly decreased. BSO sensitized MDA-MB-231/RR cells to radiotherapy, which resulted in decreased GSH level and increased ROS level and apoptosis. Radioresistant TNBC cells showed distinct metabolic and lipidomic characteristics compared to their parental cells. We suggested activated GSH, PC, and PE biosynthesis pathways as potential targets for treating radioresistant TNBC cells. Particularly, enhanced radiosensitivity was achieved by inhibition of GSH biosynthesis in MDA-MB-231/RR cells.
