Abstract:
The experiment was designed to compare the changes of cytoskeleton (including tubulin and actin) and cell surface fibronectin (FN) between NIH 3T3 cell line and transformed NIH 3T3 cell line by genome DNA of human lung adenocarcinoma cell line AGZY. We stained and observed these cells using immunohistochemical methods with antibody against bovine brain tubulin, phalloidin and self-made affinity column purified antibody against porcine plasma FN.Our results showed that the bundles of actin and tubulin are damaged seriously, demonofrating an unclear cytoskeleton structure and diffused fluorescence over the cells when they were transformed. The amount of membrane FN on transformed cell surface decreases significantly which is only 1/9 of NIH 3T3. The FN distribution altered markedly from thin threadlike network to spots and speckles.These results suggested that cell transformation was a complex event including the changes of cytoskeleton system and cell surface glycoproteins. In addition, it might also indicate that cause and effect relationship existed between these changes and the alteration of cell phenotype and loss of growth control.
