Project description:To identify prostate cancer-specific gene expression, we have employed whole cDNA microarray expression profiling between benign prostate hypertrophy and prostate cancer. We performed needle biopsy of patients with prostatic hyperplasia who were suspected as prostate cancer for minor high level (4.0-10 ng/ml). As a result of needle biopsy, we used the tissue of patients with prostatic hyperplasia that prostate cancer was denied for cDNA microarry analysis. Furthermore, we also performed needle biopsy of patients that prostate cancer should have been strongly suspected because of high PSA. Needle biopsies were performed after we obtained informed consent from patients with the document approved from the Graduate School of Medical Science, Kanazawa University.

Gene expression profile was determied in each of normal prostate samples and prostate cancer samples. Then the profiles were compared between normal prostate samples and prostate cancer samples.

Project description:In this study, comparison of gene expression profiles in benign epithelia from men with prostate cancer to those of men without prostate cancer reveal differences in several genes associated with prostate cancer. Custom Agilent 44K whole human genome expression oligonucleotide microarrays were used to profile benign epithelium from prostate needle biopsies from 15 men with high grade(Gleason 8-10) prostate cancer and 14 age- and BMI-matched controls. All samples were laser-capture microdissected and total RNA isolated and amplified prior to hybridization against a common reference pool of prostate tumor cell lines

Project description:Molecular and genomic analysis of microscopic quantities of tumor from formalin-fixed and paraffin-embedded (FFPE) biopsies has many unique challenges. Here we evaluated the feasibility of obtaining transcriptome-wide RNA expression to measure prognostic classifiers from diagnostic prostate needle core biopsies. 158 samples from diagnostic needle core biopsies (Bx) and radical prostatectomies (RP) were collected from 33 patients at three hospitals, each patient provided up to 6 tumor and benign samples. Genome-wide transcriptomic profiles were generated using Affymetrix Human Exon arrays for comparison of gene expression alterations and prognostic signatures between the Bx and RP samples.

Project description:Comparison of miRNA expression profiles in a small set of prostate needle core biopsies or fine needle aspirates. Keywords: Expression profiling of prostate needle core biopsies MicroRNA expression was compared between a pooled normal sample consisting of 10 separate normal adjacent to tumor prostate needle core biopsies, two prostate tumor cell lines (PC3 and LNCaP), two needle core biopsies, and a fine needle aspirate of a prostate tumor metastasis to the supraclavicular lymph node. MicroRNA was isolated from fresh frozen tissue sections of the needle core biopsies using the mirVana miRNA Isolation kit from Ambion per the manufacturer's instructions. MicroRNA was amplified using 10 ng input and 750 ng of amplified material was subsequently labeled for hybridization. All samples were normalized to the same normal prostate control.
