PURPOSE About 15% of colorectal cancers harbor microsatellite instability (MSI). MSI-associated gene expression changes have been identified in colorectal cancers, but little overlap exists between signatures hindering an assessment of overall consistency. Little is known about the causes and downstream effects of differential gene expression. EXPERIMENTAL DESIGN DNA microarray data on 89 MSI...
BACKGROUND Overweight and obesity are associated with increased risk of at least 13 different types of cancer. METHODS Data from the United States Cancer Statistics for 2014 were used to assess incidence rates, and data from 2005 to 2014 were used to assess trends for cancers associated with overweight and obesity (adenocarcinoma of the esophagus; cancers of the breast [in postmenopausal wome...
■ Colorectal (bowel) cancer is the second most common cause of cancer death in England and Wales. Early detection and good management result in improved survival rates. ■ Flexible sigmoidoscopy is the most appropriate initial investigation for the majority of patients with left sided colon symptoms. ■ There is a clear correlation between colonoscopy completion rates and the number and frequency...
INTRODUCTION Management of malignant colorectal polyps is controversial. The options are resection or surveillance. Resection margin status is accepted as an independent predictor of adverse outcome. However, the rate of adverse outcome in polyps with a resection margin of <1mm has not been investigated. METHODS A retrospective search of the pathology database was undertaken. All polyp cance...
ncRNAs are important regulatory molecules and involve in many physiological cellular processes. Small nucleolar RNA host gene 1 (SNHG1) is a host to 8 snoRNAs and is located in 11q12.3 region of the chromosome. It has been reported to be involved in several cancers. However, the role of SNHG1 in the tumorigenesis of colorectal cancer is still unknown. In this study, SNHG1 was upregulated in col...
Lipid metabolic disturbances are related to many diseases, such as obesity, diabetes, and certain cancers. Notably, lipid metabolic disturbances have been reported to be a risk factor for colorectal cancer. Nuclear receptors act as ligand-dependent transcription regulators and play key roles in the regulation of body lipid metabolism and the development of many cancers. Retinoic acid receptor-r...
In this paper we describe a statistical analysis of the European Molecular Library p53 mutation database comparing p53 mutations occurring in breast, colorectal, liver, lung, and ovarian cancers. The analyses show that mutation hot spots vary by cancer and that base pair changes and predicted amino acid changes in the gene product vary by cancer and by codon. The analyses use relative frequenci...
