Project description:RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer may help doctors identify biomarkers related to cancer.
PURPOSE: This laboratory study is using gene expression profiling to evaluate normal tissue and tumor tissue from patients with colon cancer that has spread to the liver, lungs, or peritoneum.
Project description:The most relevant pomegranate phenolics (ellagitannins and ellagic acid) are extensively metabolized by the human gut microbiota to yield a number of metabolites called urolithins (mainly Uro-A). Urolithins have been reported to regulate in vivo the expression of genes involved in inflammation and cancer. Our hypothesis is that urolithins can be detected in the human colon mucosa where these metabolites can exert anti-inflammatory and anti-cancer activities. After colonoscopy and diagnosis, colorectal cancer patients will consume capsules containing three different pomegranate extract formulations until surgery. The aims of this trial are:
* To evaluate the disposition of pomegranate phenolics and urolithins in tumoral and normal colon tissues.
* To evaluate gene expression profiling and protein markers in tumoral and normal colon tissues from these patients.
* To compare different pomegranate extract formulations on the above.
Project description:This SuperSeries is composed of the following subset Series:; GSE11940: Topoisomerase II inhibition involves characteristic chromosomal expression patterns: Doxorubicin study; GSE11941: Topoisomerase II inhibition involves characteristic chromosomal expression patterns: Trovafloxacin study Experiment Overall Design: Refer to individual Series
Project description:GENPROS aims to analyse the outcomes of patients with rare gene mutations in the cancer predisposition genes, BRCA1, BRCA2, HOXB13, and Lynch Syndrome, after a diagnosis of and treatment for prostate cancer (PCa). The study includes a cohort of gene mutation carriers with PCa matched with a control group of men with PCa who are known not to carry a mutation in the same gene. Clinical data regarding treatment and patient outcome will be collected retrospectively and prospectively. Archived tumour samples will also be collected for tumour profiling. A blood or saliva sample will be taken, if the participant consents to this part of the study, for genetic profiling to investigate any association of other inherited factors with PCa outcomes. Information obtained from this study will be of critical importance to support clinical trials investigating the most appropriate management of PCa in this group of patients at increased risk of prostate cancer.
