Investigation of HER-2 codon 655 single nucleotide polymorphism frequency and c-ErbB-2 protein expression alterations in gastric cancer patients.
AIM To investigate both whether the risk of gastric cancer is associated with the Ile/Val single nucleotide polymorphism (SNP) of human epidermal growth factor receptor-2 (HER-2) transmembrane domain-coding region at codon 655 and the suggested existence of HER-2 expression in gastric cancer cases in a Turkish patient group. METHODS Polymerase chain reaction (PCR) followed by restriction frag...
متن کاملCorrelation Of Her-2/Neu And Tp53 Expressions With Clinicopathologic Characteristics In Infiltrative Ductal Breast Carcinomas
Objective: To review Her-2/neu and Tp53 status and their correlation with all other prognostic clinicopathologic features of infiltrative ductal breast carcinomas. Materials and Methods: This cross sectional study was performed on 139 patients with infiltrative ductal breast carcinoma who were diagnosed between May 2000 and March 2006 at the surgery and pathology departments of Alzahra Hosp...
متن کاملEvaluation of Expression of EGFR, HER-2 and COX-2 in Colorectal Cancer
Background and objective: EGFR and HER-2 are two members of ERbB/HER family of Type I Transmembrane growth factor receptors. Cox2 is an enzyme responsible for the conversion of arachidonic acid to prostaglandins, which has a major role in angiogenesis and can modelate tumor growth. The aim of this study was to determine the level of expression of EGFR, HER-2 and Cox2 in colorectd cancer. Mater...
متن کاملHER-3 expression in HER-2-amplified breast carcinoma
AIM OF THE STUDY To determine whether the expression of HER-3 influences the survival of HER-2 positive patients with breast cancer (BC). MATERIAL AND METHODS In the present work, the expression of HER-3 in a group of 35 HER-2 positive patients with BC was studied by performing immunohistochemistry (IHC) in formalin-fixed paraffin embedded tissues. RESULTS Higher HER-3 status if estimated b...
متن کاملHER-2 gene amplification in human breast cancer without concurrent HER-2 over-expression
BACKGROUND Testing for human epidermal growth factor receptor-2 (HER-2) in breast cancer is performed by either immunohistochemistry (IHC) or in situ hybridization (ISH). The growth factor receptor-bound protein-7 (GRB7) gene is in close proximity to HER-2 on chromosome 17q11-12 and codes a signal transduction molecule shown to be an independent adverse marker in breast cancer. METHODS HER-2 ...
