TranscriptomicsSRRM4 Expression and the Loss of REST Activity May Promote the Emergence of the Neuroendocrine Phenotype in Castration-Resistant Prostate Cancer
The neuroendocrine (NE) phenotype is associated with the development of metastatic castration-resistant prostate cancer (CRPC). Our objective was to characterize the molecular features of the NE phenotype in CRPC. Expression of chromogranin A (CHGA), synaptophysin (SYP), androgen receptor (AR), and ...

TranscriptomicsA Characterization of Osteoblastic and Osteolytic Proteins in Prostate Cancer Bone Metastases
Our goal was to determine whether previously identified and novel proteins are associated with the osteoblastic or osteolytic response in clinical specimens of PCa bone metastases. Custom Agilent 44K whole human genome expression oligonucleotide microarrays were used to profile 14 PCa metastases fro...

TranscriptomicsCellular adhesion promotes prostate cancer cells escape from dormancy
Dissemination of prostate cancer (PCa) cells to the bone marrow is an early event in the disease process. In some patients, following initial treatment, disseminated tumor cells (DTC) proliferate to form active metastases after a prolonged period of undetectable disease known as tumor dormancy. Iden...

TranscriptomicsSingle Cell Transcriptomic Analysis of Prostate Cancer Cells
The ability to interrogate circulating tumor cells (CTC) and disseminated tumor cells (DTC) is restricted by the small number detected and isolated (typically <10). We wanted to determine if a commercially available technology could provide a transcriptomic profile of a single prostate cancer (PCa)...

TranscriptomicsOsteoblastic response in human bone marrow stromal cells
Our goal was to determine whether osteoblastic LuCaP 23.1 prostate cancer xenograft tumors can elicit an osteoblastic response at the gene expression level in human bone marrow stromal cells. Custom Agilent 44K whole human genome expression oligonucleotide microarrays were used to profile bone marro...

TranscriptomicsTumor Cell Heterogeneity and Dormancy in Single Disseminated Prostate Cancer Cells
Prostate cancer (PCa) disseminated tumor cells (DTC) in the bone marrow (BM) can remain dormant for prolonged periods before recurrence. Our aim was to characterize individual prostate DTC, analyze tumor cell heterogeneity, and identify markers of tumor dormancy. Custom Agilent 44K whole human geno...
