Molecular Analysis of Microsatellite Instability in Hereditary Non Polyposis Colon Carcinoma Patients from North-East Iran
Background and Objectives: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant cancer predisposition syndrome caused by germ-line mutations in DNA mismatch repair genes. Tumors arising as a result of these mutations display instability in a sequence area known as microsatellites. Studies have shown that some Bethesda markers (BAT25, BAT26) are more efficient than other...
متن کاملShould the grading of colorectal adenocarcinoma include microsatellite instability status?
Adenocarcinomas of the colon and rectum are graded using a 2-tiered system into histologic low-grade and high-grade tumors based on the proportion of gland formation. The current grading system does not apply to subtypes of carcinomas associated with a high frequency of microsatellite instability (MSI), such as mucinous and medullary carcinomas. We investigated the combined effect of histologic...
متن کاملThe pathological phenotype of colon cancer with microsatellite instability.
INTRODUCTION Colorectal cancer is a common malignant disease, caused by different aetiologies and molecular pathways. Heterogeneous results have been published regarding the association of microsatellite instability and clinicopathological features. The aim of this study was to compare clinicopathological features of microsatellite unstable tumours with stable ones. METHODS Data were collecte...
متن کاملMicrosatellite Instability in Medullary Carcinoma of the Colon
Medullary carcinoma (MC) of the large intestine is a relatively new histological type of adenocarcinoma characterized by poor glandular differentiation and an intraepithelial lymphocytic infiltrate. MC can be associated to a defective mechanism for DNA mismatch repair, caused by the so-called microsatellite instability (MSI). We present the case of a 44 years old Caucasian woman, who referred t...
متن کاملAllelic imbalance and microsatellite instability in prostatic adenocarcinoma.
Although prostate cancer is one of the most common malignancies of males in Western countries, relatively little is known about the molecular mechanisms involved in tumor initiation and progression. Allelic loss studies have suggested the involvement of multiple tumor suppressor genes (TSGs), but few detailed studies of all chromosomes have been performed. In an effort to localize and identify ...
