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

ABSTRACT: 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.

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).

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.

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

Project description: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.

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)

Targeting NSD2 in mouse prostate cancer cells

Project description:Transcriptome analysis of mouse prostate cancer cell line (NPK) silenced for Nsd2 using shRNA or treated with MCTP--39. NPK prostatre cancer cells are derived Nkx3.1CreERT2/+ ;Ptenflox/flox;KrasLSL-G12D/+ mice, and were used to silence the histone methyltransferase NSD2 or treat them with the NSD2 inhibitor MCTP39 for subsequent gene expression profiling by RNAseq

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).
