Project description:To investigate the gene expression differences between the normal peripheral zone glands compared to the moderatly and poorly differentiated tumor glands of the prostate. Laser microdissection of prostate cancer tissues to separate glands from stroma followed by RNA extraction from the glands and whole Genome Microarray. We have pooled normal glands from 10 patients, moderately differentiated tumor from 5 patients and poorly differentiated tumors from 4 patients with prostate carcinomas.

Project description:The occurrence of cancer is not equally distributed across the three zones of the prostate gland; the peripheral (PZ), central and transition zones (TZ). The majority (~70%) of diagnosed prostate cancer (PCa) is found in the PZ compared to the TZ. In this study we comprehensively measure whole genome expression by next-generation sequencing of the PZ and TZ from prostate tissue. Our aim was to identify the molecular and metabolic differences between the two zones that could underlie the differential susceptibility to PCa incidence. Following histological assessment of tissue adjacent to the biopsies used for RNAsequencing we identified 4 out of the 18 samples to be cancerous. Although these are included in the ArrayExpress submission, they were not included in the final analysis of data that reported the molecular differences between morphologically normal peripheral and transition zones.

Project description:Objective. Identify novel genes and pathways specific to superficial (SZ), middle (MZ) and deep zones (DZ) of normal articular cartilage. Methods. Articular cartilage was obtained from knees of 4 normal human donors. The cartilage zones were dissected on a microtome. RNA was analyzed on human genome arrays. Data obtained with human tissue were compared to bovine cartilage zone specific DNA arrays. Genes differentially expressed between zones were evaluated using direct annotation for structural or functional features, and by enrichment analysis for integrated pathways or functions. Results. The greatest differences were observed between SZ and DZ in both human and bovine cartilage. The MZ was transitional between the SZ and DZ and thereby shared some of the same pathways as well as structural/functional features of the adjacent zones. Cellular functions and biological processes enriched in the SZ relative to the DZ, include most prominently ECM receptor interactions, cell adhesion molecules, regulation of actin cytoskeleton, ribosome-related functions and signaling aspects such as Interferon gamma, IL4, CDC42Rac and Jak-Stat. Two pathways were enriched in the DZ relative to the SZ, including PPARG and EGFR_SMRTE. Conclusion. These differences in cartilage zonal gene expression identify new markers and pathways that govern the unique differentiation status of chondrocyte subpopulations. 12 samples, 4 donors, 3 conditions each donor (SZ, MZ and DZ), 0 donor replicates, comparisons made between SZ, MZ and DZ to identify differentially expressed genes.
