| Abstract |
Expression of mRNA for heregulin (HRG), a member of the epidermal growth factor (EGF) family and its receptors, ErbB-3 and ErbB-4, were evaluated in human upper gastrointestinal (GI) mucosa. Multi-target reverse-transcriptase polymerase chain reaction (RT-PCR) analysis using capillary electrophoresis and laser-induced fluorescence allowed us to quantify the minute amounts of mRNA from one biopsy specimen with high sensitivity. HRG, ErbB-3 and ErbB-4 mRNA were detected in esophagus, stomach and duodenum and the highest expression was found in duodenum. In gastric cancer, mRNA for ErbB-4 was significantly overexpressed. Immunoreactivity of ErbB-4 in carcinoma cell membrane was also confirmed. These findings suggest that HRG and its receptors, ErbB-3 and ErbB-4 may be physiologically significant in the human upper GI mucosa, especially in duodenum, and that ErbB-4 may contribute to the growth of gastric cancer. |
