Detection of genetic alterations in mouse lung adenocarcinomas by two-dimensional gel electrophoresis.

Author information

Department of Pathology, Medical College of Ohio, Toledo, Ohio, USA.


DNA from 14 mouse lung adenocarcinomas and 7 normal lungs were examined by 2-dimensional gel electrophoresis (2-DGE) for genetic alterations. 2-DGE profiles from tumor samples were compared with those profiles from normal lung tissues through a computer-assisted color overlay system. Compared to the profiles in normal lung DNA, 6 spots were amplified and 16 spots were partially reduced in their intensity in tumors. Two spots were detectable only in tumor tissues. These altered spots indicate genetic changes in mouse lung tumor development. The identification of these genetic alterations is probably important in understanding mouse lung carcinogenesis.
