Expression data from uncastrasion and castration tumor from LNCAP Orhotopic xenograft models of prostate cancer

Project description:To identify molecular singnal alterations between androgen dependent prostate cancer and castration resistant prostate cancer, we performed interspecies comparative microarray analyses using RNAs prepared from uncastrasion and castration tumor from LNCAP Orhotopic xenograft models of prostate cancer. microarray data from uncastrasion and castration tumor revealed that the gene expression profile is most significantly altered in between androgen dependent prostate cancer and castration resistant prostate cancer. Comparative analyses of LNCAP Orhotopic xenograft models of prostate cancer showed that genes involved in androgen dependent and androgen independent tumor were significantly altered. We prepared RNA samples from 4 samples uncastrasion and 4 samples castration tumors from LNCAP Orhotopic xenograft models of prostate cancer . High-quality RNA samples were subjected to microarray analysis using the Affymetrix Human Gene 2.0 ST platform, and only those results that passed examinations for quality assurance and quality control of the Human Gene 2.0 ST arrays were retrieved. In total, we obtained gene expression profiles from the following samples: 4 samples uncastrasion and 4 samples castration tumors

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.

LNCAP xenograft prostate cancer progression model in NOD-SCID mice

Project description:Xenografts are useful in vivo tumour models for investigating cancer progression, therapeutic responses and predicting anti-cancer drug response in patients with cancer of a similar phenotype. We have generated bulk RNA-seq data from LNCaP xenografts of a large and well-annotated prostate cancer progression study, investigating responsiveness and subsequent resistance to therapies targeting the androgen receptor (AR). LNCaP xenograft tumour establishment and initial growth are dependent on androgens in male mice (PRE-CX / pre-castration group). Upon castration, AR activity and tumour growth are suppressed (POST-CX / post-castration group), however, this initial responsiveness to castration reproducibly gives way to castration-resistance (CRPC / castration-resistant prostate cancer). Further treatment of CRPC with the AR targeting drug enzalutamide (ENZ) initially provides a therapeutic response (ENZ Sensitive; ENZS), however, resistance emerges in time (ENZ Resistant; ENZR).

Characterization of gene profile between ALDH high LNCaP cells and ALDH low LNCaP cells

Project description:Acquisition of prostate cancer stem cells (PCSCs) manifested during androgen ablation therapy (ABT) contributes to castration-resistant prostate cancer (CRPC). However, little is known about the specific metabolites critically orchestrating this process. Here, we show t+B13hat IMPA1-derived inositol enriched in PCSCs is a key metabolite crucially maintaining PCSCs for CRPC progression and ABT resistance.

RNA sequencing of LNCaP cells treated with castration and/or enzalutamide

Project description:The goal of this study was to determine how androgen receptor inhibition alters transcriptional programs in prostate cancer cells. LNCaP prostate cancer cells were grown in 10% charcoal-stripped serum (CSS) supplemented with 0.5 nanomolar dihydrotestosterone (DHT), in CSS without DHT modeling castration, with CSS + DHT but in the presence of 10 micromolar enzalutamide, or in CSS without DHT (castrated) and in the presence of enzalutamide for 72 hours. Analysis shows that androgen receptor target genes are reduced with castration, enzalutamide or the combination of castration + enzalutamide.

THEM6-mediated lipid remodelling sustains stress resistance in cancer (Part3 : THEM6 KO in LNCaP AI)

Project description:Despite the clinical benefit of androgen-deprivation therapy (ADT), the majority of patients with advanced prostate cancer (PCa) ultimately develop lethal castration-resistant prostate cancer (CRPC). In this study, we identified thioesterase superfamily member 6 (THEM6) as a marker of ADT resistance in PCa. In patients, THEM6 expression correlates with progressive disease and is associated with poor survival. THEM6 deletion reduces in vivo tumour growth and restores castration sensitivity in orthograft models of CRPC. Mechanistically, THEM6 is located at the endoplasmic reticulum (ER) membrane and controls lipid homeostasis by regulating intracellular levels of ether lipids. As a consequence, THEM6 loss in CRPC cells significantly alters ER function, preventing lipid-mediated induction of ATF4 and reducing de novo sterol biosynthesis. Finally, we show that THEM6 is required for the establishment of the MYC-induced stress response. Thus, similar to PCa, THEM6 loss significantly impairs tumorigenesis in the MYC-dependent subtype of triple negative breast cancer. Altogether our results highlight THEM6 as a novel component of the treatment-induced stress response and a promising target for the treatment of CRPC and MYC-driven cancer.

Altered expression of long noncoding RNAs in LNCaP castration resistant prostate cancer cell lines

Project description:Castration-resistant prostate cancer (CRPC) that arise after the failure of androgen deprivation therapy is a leading cause of deaths in prostate cancer patients.However, its underlying mechanism is not fully understood. Long noncoding RNAs (lncRNAs) act as crucial regulators in a lot of human cancers, yet their potential roles and molecular mechanisms in CRPC are poorly understood.The goal of this study is to identify the differentially expressed lncRNAs in LNCaP cells and its two castration resistant sublines. Our study reveals that deregulation of lncRNAs is involved in the initiation and progression of CRPC.
