Predicting drug response in human prostate cancer from preclinical analysis of in vivo mouse models (I)

ABSTRACT: Analysis of the transcriptome of mouse models of prostate cancer after treatment with rapamycin and PD0325901 combination therapy or standard of care docetaxel. The Nkx3.1CreERT2/+; Ptenflox/flox; KrasLSL-G12D/+ (NPK mice) was used in this study. Two months after tumor induction, mice were randomly assigned to vehicle (Veh) or treatments groups, such as rapamycin and PD0325901 (RAPPD) or docetaxel (Docetaxel). For the treatment groups mice were administered rapamycin (10 mg/kg) and PD0325901 (10 mg/kg) or docetaxel (10 mg/kg) for 5 days (SHORT) or for 1 month (LONG). At the end of the treatment, mice were euthanized, tumors harvested and snap frozen for subsequent molecular analysis. Total RNA obtained from prostate tumors/tissues. Prostate tumors/tissues were harvested and processed for RNA isolation and transcriptome analysis using the MagMAX RNA isolation kit (Ambion). Total RNA was amplified and labelled for subsequent microarrays hybridization using the Illumina TotalPrep RNA Amplification Kit.

Predicting drug response in human prostate cancer from preclinical analysis of in vivo mouse models (II)

Project description:Analysis of the transcriptome of allografted mouse tumors after treatment with rapamycin and PD0325901. Nkx3.1CreERT2/+; Ptenflox/flox; KrasLSL-G12D/+ (NPK mice) were induced and their tumors removed to generate allograft lines by implanting a 1.5 mm3 tumor fragment in the subcutaneous space of athymic nude mice. Allografted NPK tumors were allowed to grow until they reached a volume of 1 cm3, at which moment they were randomly assigned to either vehicle (Veh) or combination therapy using rapamycin and PD0325901 (RAPPD). Allografted mice were administered rapamycin (10 mg/kg) and PD0325901 (10 mg/kg) during five consecutive days (Allo SHORT). Mice were euthanized in the fifth day 6 hours after having received the last treatment and the tumors were harvested and snap frozen for subsequent molecular analysis. Total RNA obtained from prostate tumors/tissues. Prostate tumors/tissues were harvested and processed for RNA isolation and transcriptome analysis using the MagMAX RNA isolation kit (Ambion). Total RNA was amplified and labelled for subsequent microarrays hybridization using the Illumina TotalPrep RNA Amplification Kit.

ETV4 promotes metastasis in response to combined activation of PI3kinase and RAS signaling in a mouse model of advanced prostate cancer

Project description:Analysis of the transcriptome of mouse models of prostate cancer. NP (Nkx3.1CreERT2/+; Ptenfloxed/floxed) mice develop non-metastatic tumors while NPK (Nkx3.1CreERT2/+; Ptenfloxed/floxed; KrasG12D/+) mice develop metastatic tumors The NPK mice are also analyzed at early and late stages of tumorigenesis (1 vs. 3 months after induction) Total RNA obtained from prostate tumors of different genotypes and at different stages of dissease as indicated

Cross-species analysis of genome-wide regulatory networks identifies a synergistic dependency between FOXM1 and CENPF that drives prostate cancer malignancy

Project description:Analysis of the transcriptome of mouse models of prostate cancer to assemble a mouse prostate cancer interactome. To assemble the mouse prostate cancer interactome, we collected 13 distinct mice or genetically-engineered mouse models (GEMMs), which together represent the full spectrum of prostate cancer phenotypes including: normal epithelium (i.e., wild-type), low-grade PIN (i.e., Nkx3.1 and APT), high-grade PIN and adenocarcinoma (i.e., APT-P; APC; Myc; NP; Erg-P; and NP53), castration-resistant prostate cancer (i.e., NP-AI), and metastatic prostate cancer (i.e., NPB; NPK; and TRAMP). To further enhance the heterogeneity afforded by this diversity of mouse models, we pharmacologically perturbed each GEMM using 13 different drugs (or appropriate vehicle). The resulting mouse prostate tissue/tumor dataset encompassed 384 expression profiles Total RNA obtained from prostate tumors/tissues of 13 mouse models of prostate cancer treated with 13 different drugs for 5 consecutive days. Prostate tumors/tissues were harvested and processed for RNA isolation and transcriptome analysis.

EVALUATION IN A MOUSE PROSTATE CANCER XENOGRAFT MODEL OF THE EFFECTIVENESS OF CYCLOPHOSPHAMIDE METRONOMIC REGIMEN

Project description:The aim of this study was to evaluate in a mouse prostate cancer xenograft model the effectiveness of cyclophosphamide metronomic regimen, as single agent or in combination with standard docetaxel therapy. We used a human prostate cancer cell line to establish tumours in mice and we treated the animals with the combination of 50 mg/kg of cyclophosphamide (per os) and 30 or 10 mg/kg of docetaxel (intraperitoneally) or with the two drugs alone. We found that metronomic cyclophosphamide alone is as efficient as docetaxel in blocking tumor growth (respectively 18% and 21% of the tumor volume reached by control group in 25 days of treatment). Immunohistochemical analysis on tumours and in vitro proliferation and FACS analyses revealed that cyclophosphamide acts downregulating cell proliferation, both in vitro and in vivo. Through microarray analysis we found the upregulation of p21 that probably together with an action on the micro-environment may explain the induction of apoptosis seen in tumor xenografts. Moreover, we found 107 genes differentially expressed upon treatment with the active metabolite of cyclophosphamide and associated with functions such as cellular movement, growth, and proliferation.

Genetic deletion of osteopontin in TRAMP mice enhances the growth of aggressive prostate cancer with feature of human neuroendocrine tumors

Project description:Osteopontin (OPN) is a secreted glycoprotein, belonging to the non-structural extracellular matrix (ECM), and its over expression in human prostate cancer cells has been associated with disease progression, androgen independence and metastases. Nevertheless the pathophysiology of OPN in prostate tumorigenesis has never been studied. We crossed TRansgenic Adenocarcinoma of the Mouse Prostate (TRAMP) mice with OPN deficient (OPN-/-) mice and followed tumor onset and progression in these double mutants. Ultrasound examination detected the early onset of a spherical homogeneous tumor in about 60% of OPN-/- TRAMP mice that seldom occurs in parental TRAMP mice. Histology and immunohistochemistry characterized these tumors for being Tag positive but negative for AR, highly proliferative and endowed of neuroendocrine (NE) features. Gene expression profiling showed up-regulation of genes involved in tumor progression, cell cycle and neuronal differentiation in OPN-deficient versus -sufficient TRAMP tumors. Down-regulated genes included key genes of TGFï?¢ pathway, and a role for TGFï?¢ in NE differentiation of prostate cancer was also confirmed at the protein level. Furthermore, NE genes and particularly those characterizing early prostatic lesions of OPN-deficient mice were found to correlate with those of human NE tumours. These data underscore a novel role of OPN at early stages of prostate cancer growth, protecting against the development of aggressive NE tumors. Total RNA obtained from prostate tumors from 18 and 30 weeks old TRAMP mice, compared to RNA extracted from prostate tumors and prostate tissue from Osteopontin-deleted TRAMP mice

The mTOR pathway is necessary for survival of mice with short telomeres.

Project description:Gene expression profiles of Terc+/+ and generation 2 (G2) Terc-/- male mice fed rapamycin or control diet during 2 months. Rapamycin diet contains encapsulated rapamycin at 42 ppm (mg of drug per kg of food); control diet contains coating material (Eudragit S100). Rapamycin was microencapsulated by Rapamycin Holdings Inc. (San Antonio, Texas) and was then incorporated into 5LG6 mouse chow (TestDiet, London, UK).

B-Raf activation cooperates with PTEN loss to drive c-Myc expression in advanced prostate cancer

Project description:Anaysis of the response to different therapeutic agents at the transcriptional level. The design of the experiment allows to determine how the comnination target therapy (Rapamycin + PD0325901) treatment shifted the transcriptome towards a less aggressive or even a wild type phenotype. It also allows exploring the molecular changes involved in the transition from a non metastatic to a metastatic prostate cancer mouse model. Total RNA obtained form vehicle treated Nkx3.1CE2/+; Ptenf/f; BrafCA/+ (n=3), combinatorial Rapamycin and PD0325901 treated Nkx3.1CE2/+; Ptenf/f; BrafCA/+ (n=3) and vehicle treated intact Nkx3.1CE2/+; Ptenf/f (n = 6) prostate. Please contact Cory Abate-Shen (cabateshen@columbia.edu) and Jingqiang Wang (jw2639@columbia.edu) for questions about the submission.
