Withaferin A (WA) causes cell death in prostate cells.

ABSTRACT: Withaferin A (WA), a major chemical component of an Indian herb Withania somnifera, induces cell death (apoptosis/necrosis) in a variety of tumor cells, but its molecular mechanism remains elusive. We report that WA induces cell death selectively in high-grade prostate (PC-3 and DU-145) and tongue (SAS) cancer cells but not in normal human fibroblast (TIG-1) and low-grade prostate cancer (LNCaP) cells. To identify genes whose expression levels were up- or down-regulated in prostate cancer cells following WA treatment, we examined the transcriptome profiles of mRNA prepared from TIG-1, LNCaP, PC-3 and DU-145 cells using Agilent’s Whole Human Genome Microarray.

Withaferin A (WA), a major bioactive component of the Indian herb Withania somnifera, induces cell death (apoptosis/necrosis) in multiple types of tumor cells, but the molecular mechanism underlying this cytotoxicity remains elusive. We report here that 2 μM WA induced cell death selectively in androgen-insensitive PC-3 and DU-145 prostate adenocarcinoma cells, whereas its toxicity was less severe in androgen-sensitive LNCaP prostate adenocarcinoma cells and normal human fibroblasts (TIG-1 and K ...[more]

Expression data from docetaxel-resistant prostate cancer cell lines

Project description:Docetaxel-based chemotherapy is the standard first-line therapy in metastatic castration-resistant prostate cancer. However, most patients eventually develop resistance to this treatment. The aim of the study was to identify key molecular genes and networks associated with docetaxel resistance in 2 models of docetaxel-resistant castration-resistant prostate cancer cell lines. DU-145 and PC-3 cells were converted to docetaxel-resistant cells, DU-145R and PC-3R, respectively. Whole-genome arrays were used to compare global gene expression between these 4 cell lines. Arrays were performed by triplicate for each cell line.

Triple SILAC based quantitative MS approach to determine Withaferin A regulated proteins in prostate cancer

Project description:Withaferin A (WA) is a lactone extracted from Withania somnifera commonly known as Ashwagandha. WA has several therapeutic benefits. The current study was aimed to identify biomarkers that could be targeted by WA in prostate cancer (PCA) cells. We have used SILAC approach to identify WA-regulated proteins at 4 h and 24 time points in three PCA cell lines such as LNCaP, 22Rv1 and DU-145. Ontology prediction suggested that WA treatment can upregulate stress-responsive pathways and shutdown translation and cell metabolism to conserve energy. The cytoprotective stress granule (SG) protein G3BP1 showed upregulation in all the three tested cell lines in response to WA treatment, and subsequently, SGs formed at a higher rate in the WA treated cells. Knockdown (KD) of G3BP1 blocked WA-induced SG formation and reduced the cell survival. We speculate that the activation of G3BP1 and the formation of SGs might constitute a mechanism by which PCA cells induce cell protection after WA- treatment. Knock down of SG proteins such as G3BP1 could help to evade the cytoprotective effects of WA and to assist in the sensitization of cells.

A Multi-loop, Double-cube Microarray Design Applied to Prostate Cancer Cell Lines with Variable Sensitivity to Histone Deacetylase Inhibitors

Project description:Implementation of a complex design for a microarray experiment on resistance mechanisms of histone deacetylase inhibitors (HDACI). To improve our understanding of the underlying mechanism of HDACI resistance in prostate cancer cells, we designed a novel ‘‘multiple-loop, double-cube’’ cDNA microarray experiment. In the experiment DU-145 and PC3 cells were treated with two different HDACIs (vorinostat and valproic acid) and incubation periods (48 and 96 hours). Preprocessing included exploratory analyses of the quality of the arrays and intensity-dependent within-array Loess normalization. An ANOVA model was used for inference. The results were validated by Western blot analysis of known treatment targets.

Role of macrophages in invadopodia formation

Project description:The first experiment involved the DU-145 tumor cell samples cultured with or without macrophages. This experiment was planned with an aim to evaluate the gene expression changes that might occur in DU-145 cells when grown in proximity to macrophages as compared to DU145 cells being grown alone. Similarly, the second experiment, involved the macrophage samples cultured with or without the DU-145 cells. This experiment was planned with an aim to evaluate the gene expression changes that might occur in Macrophages when grown in proximity to DU-145 cells .

Global Reactivation of Epigenetically Silenced Genes in Prostate Cancer

Project description:Transcriptional silencing associated with aberrant promoter hypermethylation is a common mechanism of inactivation of tumor suppressor genes in cancer cells. To profile the genes silenced by hypermethylation in prostate cancer, we screened an expression microarray for genes reactivated in the LNCaP, DU-145, PC-3 and MDA2b prostate tumor cell lines after treatment with the demethylating drug 5-aza-2 deoxycytidine (5Aza-dC) and histone deacetylation inhibiting drug trichostatin A (TSA).

miRNA expression in LNCaP, PC3, Du-145 and RWPE-1 cell lines

Project description:MiRNAs are small non-coding RNAs that regulate the expression of specific mRNA targets mainly by translational repression, mRNA deadenylation or cleavage. This series is meant to identify miRNAs deregulated in prostate cancer (PCa) by comparing the PCa cell lines LNCaP, PC3 and Du-145 to the normal prostate epithelial cell line RWPE-1. We analyzed three arrays each for LNCaP, PC3, Du-145 and RWPE-1 cell lines
