Project description:Dysregulated miRNA in human colorectal cancer (CRC) were identified through comparison between 4 CRC tumors and their adjacent normal tissues by miRNA array. Histologically-confirmed CRC were included in this study. CRC tissues and paired adjacent normal tissues were obtained from the resected surgical specimens. The adjacent normal tissue is composed of normal colonic mucosa located at approximately 10 cm away from the cancer tissue. miRNA profiling of 754 human miRNAs was performed using TaqMan Human MiRNA Array Set v3.0. Quantitative real-time polymerase chain reaction (Q-PCR) was performed using Applied Biosystems 7900HT Real-Time PCR System (Applied Biosystems). Results were analyzed by the SDS RQ Manager 1.2 software (Applied Biosystems).

Equal amount of total RNA were used for analysis.
Project description:Laser Capture Microdissected cells from archival FFPE Prostate cancer and normal adjacent tissues from 10 patients (5 CA and 5 AA) were converted to cDNA and analysed by PCR array to identify differentially expressed miRNAs between the groups. Selected differentially expressed miRNAs were further validated in tissues from 40 prostate cancer patients. The miRNAs which were differentially modulated in PCa patients in the validation set were further analysed in 32 urine samples from PCa patients and compared with 12 healthy individuals. Differentially expressed miRNAs were explored to e used as non-invasive biomarker for PCa.

Equal amount small RNA from each group was pooled prior to gene expression analysis.
Project description:H3K27me3 variations were analyzed in 8 pairs of GC and adjacent normal tissues , from 8 GC patients, using chromatin immunoprecipitation linked to microarrays (ChIP-chip) approach. ChIP-real time PCR is used to validate the microrray results. In addition, DNA methylation status also be further analyzed by Methyl-DNA immunoprecipitation- quantitative PCR.
Project description:Proteome characterization of gland confined prostate tumors and non-malignant prostate tissue. Whole cell protein extracts were purified from FFPE radical prostatectomy specimens for a total of 28 tumor samples and 8 adjacent non-malignant prostate tissues. Associated ProteomeXchange identifiers: PXD003430, PXD003452, PXD003515, PXD004132, PXD003615, PXD003636. Quantitative proteomic analysis of adjacent non-malignant prostate tissue (n=8) and gland confined prostate tumors (n=28) obtained from radical prostatectomy procedures; and bone metastatic prostate tumors (n=22) obtained from patients operated to relief spinal cord compression. At the time of surgery, most metastatic patients had relapsed after androgen-deprivation therapy, while 5 were previously untreated.
Project description:To identify which lncRNAs are differentially expressed in prostate cancer, the total RNA from prostate cancer cell lines (PC3, LNCaP), normal epithelial prostatic cells and the pool of 10 prostate tumor tissues and 10 adjacent normal prostate tissues were screened using SurePrint G3 human lncRNA microarrays (Agilent). The SurePrint G3 Human Gene array contains 16,472 lincRNAs and 34,127 mRNA genes.
