Gene expression profiling of LNCaP cells following shRNA-mediated knockdown of TMEFF2 and growth in presence and absence of dihydrotestosterone

Project description:TMEFF2 is an androgen regulated transmembrane protein mainly restricted to brain and prostate, that functions as a tumor suppressor in prostate cancer (PCa). Studies using publically available prostate cancer (PCa) datasets, reveal changes in the expression of TMEFF2 with disease stage, supporting an important role of TMEFF2 in this disease. However, the role of TMEFF2 in the biology and pathogenesis of PCa is still unknown. Using a transgenic TMEFF2 mouse, we have demonstrated that TMEFF2 overexpression modulates prostate branching morphogenesis, and androgen regulated process, during prostate regeneration. We hypothesized that TMEFF2 may have a regulatory function within androgen signaling that could explain its role in PCa. To better understand its function in androgen signaling and PCa, we compared the transcriptome of LNCaP prostate cancer cells transduced with control shRNA and shRNA targeting TMEFF2 in the presence and absence of dihydrotestosterone (DHT). The results indicated that globally, there is a significant interaction between the effects of DHT and shTMEFF2. Of the 519 genes with significant gene expression changes after DHT treatment of Scramble control cells, 208 (40%) had significant differential expression when the shTMEFF2 +DHT group was compared to Scramble +DHT group, including numerous androgen activated and androgen repressed genes.

Regulation of gene expression by JMJD5 in LNCaP prostate cancer cells

Project description:The goal of this study was to define the cohort of genes whose expression is regulated by JMJD5 function in prostate cancer. Towards this goal, LNCaP sublines stably expressing wld-type JMJD5 (LNCaP-JMJD5) were established. In addition, a control subline(LNCaP-Vector) was generated by transfection with empty vector. Both sublines were cultured in either androgen-deprived medium or in the presence of dihydrotestosterone (DHT). Subsequently, total RNA was isolated and then subjected to microarray gene expression profiling with Affymetrix GeneChip HG-U133 Plus 2.0 Arrays. A total of 4 samples were analyzed in this study. The study included two cell lines, LNCaP-Vector and LNCaP-JMJD5, that were cultured under conditions of androgen depivation (-DHT) or supplementation with dihydrotestosterone (+DHT). The LNCaP-Vector cell line served as the control for the study.

Androgen receptor-coregulators hormone responsiveness LNCaP / GSF

Project description:The text description is: LNCaP are androgen receptor expressing prostate carcinoma cells. Genital skin fibroblasts also express the androgen receptor. Cells were either proliferating or they were G0-arrested. Treatment of cells was performed with either the androgen DHT (dihydrotestosterone), the androgen analogue R1881 (methyltrienolone), or the solvent ethanol. Some hybridizations were performed in the type 1 design. In these cases, the hormone treated sample was hybridized against the ethanol treated sample on the same microarray. Hormone mediated induction or repression of gene transcription can directly be deduced from R/G normalized ratios on arrays. For other experiments, the ethanol treated control and the hormone treated experiment were hybridized on separate microarrays against a common reference of RNA. This reference was composed out of common reference batch CRG (50%) and a fibroblast RNA (50%). This reference was called mixed reference. For all experiments, the same batch of mixed reference was used. A compound treatment design type is where the response to administration of a compound or chemical (including biological compounds such as hormones) is assayed. Compound Based Treatment: Ethanol, R1881 (methyltrienolone), or DHT (dihydrotestosterone) Cell Line: LNCaP (prostate cancer) or foreskin fibroblasts Culture Synchrony: proliferation / Go-arrest Keywords: compound_treatment_design
