Project description:Colorectal cancer is a highly heterogeneous disease, with variable molecular pathogenesis, involving multiple genomic and epigenetic alterations. Despite the significant advances in the diagnosis and treatment of colorectal cancer, it remains a major cause of morbidity and mortality, especially for countries in Northern America and Europe, as also in New Zealand & Australia. In this direction, the introduction of gene expression signatures derived from multiple layers of molecular & clinical dissection, may resolve the problems of heterogeneity and improve robust disease stratification We used microarrays to monitor the global gene expression alterations of primary adenocarcinomas and matched normal samples from each patient, to unravel the critical biological processes that are involved in CRC progression
Project description:Microarray analyses for the identification of differences in gene expression patterns have increased our understanding of the molecular genetic events in colorectal cancer. We used gene expression analysis data from recurrent and non-recurrent patients with colorectal cancer to identify differentially expressed probes. Tumor tissues were taken from 81 patients with colorectal cancer, rapidly frozen in RNAlater, and isolated using Trizol. Gene expression pro?les were determined using Affymetrix HG-U133 Plus 2.0 GeneChips.We aimed to identify a molecular signature that can reliably identify colorectal cancer patients at high risk for recurrence.

Project description:This study aims to investigate differentially expressed proteins in tumor pericytes derived from colorectal cancer patients with or without liver metastasis. Tumor pericytes were isolated from tumor of colorectal cancer patients with or without liver metastasis. Then, tumor pericytes were cultured and subjected to proteomic analysis. TCAF2 was significantly increased in tumor pericytes from liver metastasis patients.
Project description:lncRNAs contributes to the development of colorectal cancer (CRC). Analysis of tumor tissues and adjacent non-tumor tissues from 6 colorectal cancer patients was conducted. Results indicate insight into molecular signature of the tumorigenesis of CRC.
Project description:Samples were taken from surgically resected tumor specimens from patients with colorectal cancer. The expression profiles were determined using the Affymetrix GeneChip Human Exon 1.0 ST Array version 2. Gene mutation status was determined using Sanger sequencing.
