Gene expression profiling of colorectal mucinous adenocarcinomas.

Purpose: Although mucinous adenocarcinomas represent 6% to 19% of all colorectal adenocarcinomas, little is known about the genome-wide alterations associated with this malignancy. We have sought to characterize both the gene expression profiles of mucinous adenocarcinomas and their clinicopathologic features.

Methods: Tumors from 171 patients with primary colorectal cancer were profiled using the Affymetrix HG-U133Plus 2.

Green tea catechins suppress the DNA synthesis marker MCM7 in the TRAMP model of prostate cancer.

Green tea catechins (GTCs) exert chemopreventive effects in many cancer models. Several studies implicate the DNA synthesis marker minichromosome maintenance protein 7 (MCM7) in prostate cancer progression, growth and invasion; representing a novel therapeutic target. In this study, we investigated the effect of GTCs on MCM7 expression in the transgenic adenocarcinoma mouse prostate model (TRAMP).

Effects of IFN-gamma and Stat1 on gene expression, growth, and survival in non-small cell lung cancer cells.

Stat transcription factors are activated by cytokines and can activate pathways important in oncogenesis. Although previous studies have identified an oncogenic role of Stat3 in lung cancer cells, the role of Stat1 is unclear. Using a mutant of Stat1 with constitutive activity (Stat1C), we examined the effect of persistent Stat1 activity on lung cancer cell growth, survival and gene expression.
