Gene expression at the level of polypeptide synthesis has been investigated in a somatic cell hybrid (20 BW-4) isolated after fusion of spontaneously transformed, tumorigenic Chinese hamster lung fibroblasts with mouse embryo fibroblasts. This hybrid exhibited suppression of tumorigenicity and retained--in addition to the parental Chinese hamster genome--copies of all mouse chromosomes as demon...
Newborn hamsters were injected subcutaneously with a suspension of finely minced Rous chicken sarcoma (Schmidt-Ruppin strain). After an interval of about 2 weeks, progressively growing sarcomas developed at the site of injection in almost all animals. Also in adult hamsters inoculated intramuscularly with the same material sarcomas developed at the site of injection within 2 to 4 months. Second...
The metabolism of low density lipoprotein (LDL) in the hamster is substantially similar to that of the human. To extend the usefulness of the hamster as an experimental model, the hamster LDL receptor gene was isolated and characterized. The gene is composed of 18 exons and 17 introns which span 26 kilobases. The introns occur at precisely the same positions as those previously determined for t...
