Gene expression analysis of enzalutamide resistant MDA PCa 2b prostate cancer cells

Project description:MDA PCa 2b is an androgen-responsive, AR-positive prostate cancer cell line. Here, we report the generation of an Enzalutamide-resistant derivative, MDA PCa 2b-EnzaR. Gene expression of MDA PCa 2b-EnzaR compared to its parental counterpart were assessed by short-read RNA sequencing.

Expression data from prostate cancer cell lines C4-2B (enzalutamide sensitive) and C4-2B-MDVR (enzalutamide resistant) cells

Project description:Prostate cancer C4-2B cells were cultured in enzalutamide in a dose-escalation manner. After sixty passages cells were resistant to enzalutamide, with a specific sets of genes been deregulated. We performed global gene expression analysis by cDNA microarrays to identify genes responsible for enzalutamide resistance in C4-2B-MDVR cells. Enzalutamide resistant C4-2B-MDVR cells were selected from C4-2B cells during long time enzalutamide treatment. Genes responsible for enzalutamide resistance were identified using C4-2B vs. C4-2B-MDVR RNA extraction and hybridization on Affymetrix microarrays.

MDA-PCa-2b cells, Control vs. ARlnc1 knockdown, AR-regulated gene signature generated by DHT treatment

Project description:(1) Transcription profiling of MDA-PCa-2b cells comparing ARlnc1 knockdown treated cells with control cells. Two methods were used to knockdown ARlnc1: siRNA or ASO. (2) Transcription profiling of MDA-PCa-2b cells comparing dihydrotestosterone (DHT) stimulated cells with vehicle treated cells. The goal is to determine AR-regulated gene expression signature in MDA-PCa-2b cells.

High-throughput profiling of mRNA from parental and Enzalutamide resistant C4-2b prostate cancer cell lines

Project description:We established an enzalutamide-resistant C4-2b prostate cell line that has an active androgen receptor by maintaining the C4-2b cell line in serially increasing concentrations of enzalutamide. Among the CRPC cell lines, we selected the C4-2b cell line because it is known to have AR variants, and we desired to identify enzymes with the ability to regulate the activity of AR variants as well as the wild type AR. After 2 months, we acquired resistant cells in even 10 uM enzalutamide. After validation of enzalutamide-resistant character, we analyzed global changes in mRNA expression by using quantitative mRNA-sequencing analysis.

Expression data of LNCaP and MDA PCa 2b cells in absence or presence of IL6

Project description:Prostate cancer (PCa) development and progression are associated with chronic inflammation. The cytokine interleukin (IL)-6 can influence progression, differentiation, survival, and angiogenesis of PCa. To identify novel pathways that are triggered by IL-6, we performed a gene expression profiling of two PCa cell lines, LNCaP and MDA PCa 2b, under treatment with 5 ng/ml IL-6. Interferon regulatory factor (IRF)9 was identified as one of the most prevalent IL-6 regulated genes in both cell lines. IRF9 is a mediator of type I interferon signaling and acts together with signal transduction and activator of transcription (STAT)1 and 2 to activate transcription of interferon responsive genes. The IL-6 regulation of IRF9 was confirmed at mRNA and protein levels by quantitative real-time PCR and Western blot, respectively, in both cell lines and could be blocked by the anti-IL-6 antibody Siltuximab. Three PCa cell lines with an autocrine IL-6 loop, PC3, DU145, and LNCaP-IL-6+, showed a high expression of IRF9. A tissue microarray with 36 malignant and adjacent 36 benign areas from prostate cancer specimens showed that IRF9 protein expression is moderately elevated in malignant areas and positively correlates with the tissue expression of IL-6. Downregulation and overexpression of IRF9 provided evidence for an interferon-independent role of IRF9 on cellular proliferation of different PCa cell lines. Furthermore, expression of IRF9 was essential to mediate the antiproliferative effects of IFN-M-NM-12. We concluded that IL-6 is an inducer of IRF9 expression in prostate cancer and a sensitizer for the antiproliferative effects of IFNM-NM-12. LNCaP and MDA PCa 2b cells were seeded in 12 wells each. The cells were starved for 24 h and half were treated with 5 ng/ml IL-6 for 18 h. Two biological replicates were performed, each in three replicates, resulting in 12 samples per cell line.

RNA-seq profiling identifies Androgen Receptor-regulated genes in prostate cancer cells

Project description:The goal of this analysis is to profile AR-regulated genes, especially non-coding RNAs in three androgen sensitive prostate cancer cell lines, MDA-PCA-2B, LNCaP and VCaP. The two cell lines were serum-starved first, followed by dihydrotestosterone (DHT) stimulation or treated with Enzalutamide (AR inhibitor) without starvation. Transcriptome profiling was generated by RNA-sequencing from polyA-selected RNA. These experiments are followed by knock-down experiments of AR and ARlnc1 in MDA-PCA-2B, and also Enzalutamide (anti-androgen) treatment of LNCaP cells.
