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

Project description: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.

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.

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).

Hypoxia-independent gene expression signature associated with radiosensitisation of prostate cancer cell lines by histone deacetylase inhibition

Project description:We aimed to investigate gene expression associated with radiosensitisation of normoxic and hypoxic prostate cancer cells by the class I/II histone deacetylase inhibitor (HDACi) vorinostat. A pronounced deregulation of DNA repair and chromatin organization genes by vorinostat in DU 145 than in PC-3 or 22Rv1 was found and was a likly mechanism underlying radiosensitisation of DU 145. Expression of these genes was generally not affected by hypoxia and was altered by vorinostat in DU 145 towards the baseline levels of PC-3 and 22Rv1. A 56-gene expression signature associated with radiosensitisation under normoxia and hypoxia, including 8 genes with baseline expression characteristic of the radiosensitising effect was generated. These findings propose a hypoxia independent expression signature to predict the radiosensitising effect of vorinostat.

Anti-proliferative, Apoptosis and Anti-migration Properties on Androgen-independent Human Prostate Cancer by a Diarylpentanoid, MS13.

Project description:Diarylpentanoids exhibit a high degree of anti-cancer activity and stability in vitro over curcumin in prostate cancer cells. Hence, this study aims to investigate the effects of a diarylpentanoid, 1,5-bis(4-hydroxy-3-methoxyphenyl)-1,4-pentadiene-3-one (MS13) on cytotoxicity, anti-proliferative, apoptosis-inducing, anti-migration properties, and the underlying molecular mechanisms on treated androgen-independent prostate cancer cells, DU 145 and PC-3. A cell viability assay has shown greater cytotoxicity effects of MS13-treated DU 145 cells (EC50 7.57 ± 0.2 µM) and PC-3 cells (EC50 7.80 ± 0.7 µM) compared to curcumin (EC50: DU 145; 34.25 ± 2.7 µM and PC-3; 27.77± 6.4 µM). In addition, MS13 exhibited significant anti-proliferative activity against AIPC cells compared to curcumin in a dose- and time-dependent manner. Morphological observation, increased caspase-3 activity, and reduced Bcl-2 protein levels in these cells indicated that MS13 induces apoptosis in a time- and dose-dependent. Moreover, MS13 effectively inhibited the migration of DU 145 and PC-3 cells. Our results suggest that cell cycle-apoptosis and PI3K pathways were the topmost significant pathways impacted by MS13 activity. Our findings suggest that MS13 may demonstrate the anti-cancer activity by modulating DEGs associated with the cell cycle-apoptosis and PI3K pathways, thus inhibiting cell proliferation and cell migration and inducing apoptosis in AIPC cells.

Treatment of prostate cancer cell lines DU-145 and LNCaP with zebularine

Project description:Cultures of DU-145 cells and of LNCaP cells were treated for 216 hours with 100ÂµM zebularine (SIGMA) in three independent biological experiments. Zebularine acts as a DNA methyltransferase (DNMT) inhibitor thereby upregulating genes that are inactivated by e.g. promotor hypermethylation. The experiment aimed to search for upregulated transcripts to provide new targets for biomarker development and therapeutic use. Total RNA of untreated and treated (100ÂµM zebularine) DU-145 cells (experiment HK_21_DU_145-HK_26_DU_145), and of untreated and treated (100ÂµM zebularine) LNCaP cells (experiment HK_27_LNCaP-HK_32_LNCaP), were subjected to Affymetrix array analysis to detail the overall expression changes after treatment with a DNMT inhibitor. Treated cells showed no obvious signs of zebularine-induced cytotoxicity as revealed by XTT assays.
