To investigate the role of NKX3.1 in prostate differentiation, we employed transcriptome analysis of mouse seminal vesicle (from 15-month-old Nkx3.1+/+ mice); mouse prostate (from 4-month-old Nkx3.1+/+ and Nkx3.1-/- mice); human prostate cells (RWPE1 cells engineered with empty vector (altered pTRIPZ), NKX3.1 wild type over-expression, and NKX3.1 (T164A) mutant over-expression); and tissue recombinants (generated from combining engineered mouse epithelial cells (seminal vesicle epithelial cells or prostate epithelial cells from 2-month-old mice) and rat UGS mesenchymal cells). Mouse tissue or human cells were snap frozen for subsequent molecular analysis.

View SamplesAnalysis 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.

View SamplesAnalysis of transcriptome of tissue recombinants (mouse seminal vesicle epithelial [SVE] cells or prostate epithelial [PE] cells, and rat urogenital sinus [UGS] mesenchymal cells) grown under the kidney capsule in athymic nude mice for 3 months. Overall design: Total RNA obtained from tissue recombinants generated from combining engineered mouse epithelial cells (SVE or PE from 2-month-old C57Bl/6J mice) and rat UGS mesenchymal cells. Tissue recombinants were harvested and processed for RNA isolation and transcriptome analysis using the RNeasy kit (Qiagen).

Overall design: Total RNA obtained from RWPE1 cells engineered with empty vector (altered pTRIPZ), NKX3.1 wild type over-expression, and NKX3.1 (T164A) mutant over-expression. Engineered RWPE1 cells were harvested and processed for RNA isolation and transcriptome analysis using the MagMAX RNA isolation kit (Ambion).

View SamplesAnalysis 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.

View SamplesConventional anti-cancer drug screening is typically performed in the absence of accessory cells (e.g. stromal cells) of the tumor microenvironment, which can profoundly alter anti-tumor drug activity. To address this major limitation, we have developed assays (e.g. the tumor cell-specific in vitro bioluminescence imaging (CS-BLI) assay) to selectively quantify tumor cell viability, in presence vs. absence of non-malignant stromal cells or drug treatment. These assays have allowed us to identify that neoplastic cells from diverse malignancies exhibit stroma-induced resistance to different anti-tumor agents. In this analysis, we evaluated the molecular changes triggered in myeloma cells by their in vitro interaction with stromal cells. The transcriptional profile of 3 human multiple myeloma (MM) cell lines (MM.1S, MM.1R, INA-6) co-cultured with stromal cells vs. when cultured alone was characterized by oligonucleotide microarray analysis, using the human U133 plus 2.0 Affymetrix GeneChip.
