Identificatinon of differentially expressed genes in Docetaxel-resistant cell lines PC3 and DU145 after combination treatment with RU486 and docetaxel

Project description:Upregulation of the glucocorticoid receptor (GR) has been identified as a possible bypass mechanism in CRPC. Recently, it has been demonstrated that the combination of docetaxel with mifepristone (D+M), an inhibitor of the GR, reinduces sensitivity to docetaxel in docetaxel resistant cell models. This study was designed to uncover and characterize molecular mechanisms responsible for this observation.

Transcription Factor Network Reveals New Treatments for Prostate Cancer Docetaxel Drug Resistance

Project description:Overcoming drug resistance is critical increasing the survival rate for prostate cancer (PCa). In this study, we modeled docetaxel resistance using two PCa cell lines, DU145 and PC3. We conducted both single cell and bulk RNA sequencing. We constructed a transcription factor (TF) network for the docetaxel sensitive and resistant variants for all cell lines and sequencing methods resulting in 8 networks. We identified shared edges and nodes that represent a shared TF network for PCa that modeled the changes after acquiring drug resistance. Using this shared TF network, we identified drivers of the resistant phenotype. Interestingly, the network constructed from the bulk sequencing dataset revealed different TF drivers of resistance compared with the network constructed from the single cells. We validated the results constructed from the single cells to demonstrate the validity of the single cell sequenced TF network. We targeted GABPA (only identified in the single cell constructed network) and successfully re-sensitized both cell lines to docetaxel treatment. Additionally, we conducted connectivity map analysis to identify potential drugs that disrupt the resistant networks. We identified trichostatin A as a potential combination treatment using the single cell sequenced network. Combination treatment of trichostatin A and docetaxel, both in vitro and in vivo PCa models decreased tumor growth. These results suggest by analyzing a population of resistant cells, identification of drivers and novel treatments is possible.

Expression data from Docetaxel-resistant prostate cancer cells

Project description:Docetaxel is the standard first line therapy for hormone-refractory prostate cancer patients. Here we generated models of Docetaxel resistance in prostate cancer cells to study the molecular pathways that drive the acquisition of resistance to this therapy. We used microarrays to detail the global program of gene expression underlying the acquisition of Docetaxel resistance in prostate cancer cells. Parental Docetaxel-sensitive prostate cancer cell lines (DU145 and 22Rv1) and selected Docetaxel-resistant cells (DU145-DR and 22Rv1-DR) were harvested for RNA extraction and hybridization on Affymetrix microarrays. Samples were analyzed in triplicates in order to increase the resolution of expression profiles.

Combination of AgNPs and DOC in PC3

Project description:Combination of AgNPs and DOC in PC3

Study of matrix proteins synthesized by DU145 and PC3 prostate cancer cells alone or in co-culture with prostate-derived fibroblasts.

Project description:Tumor microenvironment or stroma has the potency to regulate the behavior of malignant cells. Fibroblast-like cells are abundant in tumor stroma and they are also responsible for the synthesis of many extracellular matrix components. Fibroblast–cancer cell interplay can modify the functions of both cell types. We applied mass spectrometry and proteomics to unveil the matrisome in 3D spheroids formed by DU145 prostate cancer cells, PC3 prostate cancer cells or prostate derived fibroblasts. Similarly DU145/fibroblast and PC3/fibroblast co-culture spheroids were also analyzed. Western Blotting and immunofluorescence were used to confirm the presence of specific proteins in spheroids. Cancer dissemination was studied by utilizing "out of spheroids" migration and invasion assays. In the spheroid model cancer cell–fibroblast interplay caused remarkable changes in extracellular matrix and accelerated the invasion of DU145 cells. Fibroblasts produced structural matrix proteins, growth factors and matrix metalloproteinases. In cancer cell/fibroblast co-cultures basement membrane components, including laminins (3, 5, 2, 3), heparan sulphate proteoglycan (HSPG2 gene product), and collagen XVIII accumulated in a prominent manner when compared to spheroids that contained fibroblasts or cancer cells only. Furthermore, collagen XVIII was intensively processed to different endostatin isoforms by cancer cell derived cathepsin L. To sum up, fibroblasts can promote carcinoma cell dissemination by several different mechanisms. Extracellular matrix and basement membrane proteins provide attachment sites for cell locomotion promoting adhesion receptors. Growth factors and metalloproteinases are known to accelerate cell invasion. Additionally, cancer cell–fibroblast interplay generates biologically active fragments of basement membrane proteins, such as endostatin.
