Tumor Suppressor Gene Located In Liver Cancer Cells
...Next, the researchers began the arduous process of screening
the large gene for one or more mutations that might disable it. Using a method to detect mismatches in genetic material, they compared strands of DNA from tumor cells and surrounding normal tissue, and discovered mutations in the tumor samples. Th...
