Expression data from prostate cancer cell lines LNCap (androgen dependent) and DU145 (androgen independent), transfected with Pin1 or control siRNA

ABSTRACT: Pin1 inhibiton exerts anti-oncogenic effects on LNCaP and DU145 cells despite the gene regulation patterns by Pin1 were different in both cells. We investigated how Pin1 modulates the gene expressions in the androgen-dependent as well as the androgen-independent prostate cancer cell lines

Expression data from prostate cancer cell lines LNCap (androgen dependent) and DU145 (androgen independent), transfected with Pin1 or control siRNA

Project description:Pin1 inhibiton exerts anti-oncogenic effects on LNCaP and DU145 cells despite the gene regulation patterns by Pin1 were different in both cells. We investigated how Pin1 modulates the gene expressions in the androgen-dependent as well as the androgen-independent prostate cancer cell lines For the knockdown of human Pin1, the siRNAs against Pin1 (Pin1 shRNA-1: 5’-CGGCAACAGCAGCAGUGGUGGCAAA-3’ and Pin1 shRNA-2: 5’-GCCCUGGAGCUGAUCAACGGCUACA-3’) and control siRNA were purchased from Invitrogen (Stealth/siRNA duplex oligoribonucleotides)

Microarray Analysis of DU 145, LNCaP and PC-3 Prostate Cancer Cell Lines upon Docetaxel treatment

Project description:We measured the effect of docetaxel treatment to three differentially responsive prostate cancer cell lines, LNCaP, DU145 and PC-3, based on a transcriptional time course response by microarray analysis. These cell lines represent both androgen independent (DU145 and PC-3) and androgen sensitive (LNCaP) cells

Comparison of baseline global gene expression profiles of prostate cancer cell lines LNCaP and DU145

Project description:Introduction: DU145 and LNCaP are classic prostate cancer cell lines. Characterizing their baseline transcriptomics profiles (without any intervention) can offer insights into baseline genetic features and oncogenic pathways that should be considered while interpreting findings after various experimental interventions such as exogenous gene transfection or drug treatment. Methods: LNCaP and DU145 cell lines were cultured under normal conditions, followed by RNA extraction, cDNA conversion, library preparation, and RNA sequencing using the Illumina NovaSeq platform. The sequences were analyzed to identify differentially expressed genes (DEGs) and for gene ontology (GO) and pathway enrichment. Results: A total of 3916 and 2301 genes were found to be differentially upregulated and downregulated between LNCaP and DU145 cell lines, respectively. The GO and pathway analysis of up-regulated DEGs indicated significant enrichment of genes involved in extracellular matrix organization and cell-substrate adhesion, while down-regulated genes are involved in epithelial cell migration, cell death regulation, and cell proliferation. Conclusion: The results showed significant differences in baseline gene expression and cellular pathways that may account for the varying metastatic potentials between LNCaP and DU145 cell lines, which should be considered when interpreting findings after experimental interventions.

lncRNA-PCAT1 knockdown effect on the gene expression of androgen independent LNCaP (LNCaP-AI) cell line

Project description:We generated and characterized an androgen-independent LNCaP-AI cell line by long-term culture of androgen-dependent LNCaP cells in RPMI-1640 medium containing charcoal-stripped serum. This approach used to generate the line mimics the castration resistant condition for treating prostate cancer, supporting the relevance of the LNCAP-AI cell line to Castration Resistant Prostate Cancer.

Expression data from androgen treated LNCaP cells

Project description:Androgens are required for the development of normal prostate, and they are also linked to the development of prostate cancer. We used microarrays to understand the role of androgen in an androgen dependent, androgen receptor (AR) positive human metastatic cell line, LNCaP. LNCaP cells were grown in RPMI medium and they were subjected to stay in phenol-red free, RPMI with charcoal stripped serum for 48h. Synthetic androgen R1881 was added and the cells were allowed to grow for 48h. Control cells were given with corresponding amount of ethanol as vehicle which is used for the solubilization of R1881. Cells were harvested and RNA was isolated for microarray analysis.

Transcription profiling of human LNCaP cells Androgen-starved treated with gedunin and androgen, androgen alone, or vehicle alone for 24h

Project description:Gedunin is a natural product that affects LNCaP androgen-signalling by 24h; We used microarrays to detail the androgen-responsive program of gene expression affected by gedunin treatment at 24h Experiment Overall Design: LNCaP cells were grown to 50% confluency and deprived of androgen, and subsequently treated with gedunin plus androgen, androgen alone, or vehicle alone for 24h prior to direct Trizol lysis and RNA isolation
