Abstract：
:Angiogenic and poorly angiogenic tumor variants were obtained by an intraperitoneal inoculation of cells from clones of polyoma-virus transformed BALB/c 3T3 cells into syngeneic mice. The angiogenic tumor cells expressed a higher tumorigenicity phenotype and a higher capacity to produce artificial pulmonary metastases than cells from the poorly angiogenic tumors. The former cells expressed also significantly higher levels of the lymphocyte activation protein Ly-6E.1 than the former cells. The two types of cells did not differ in expression levels of CD44 and of a polyoma-virus specific membrane antigen. These results raise the possibility that the angiogenic phenotype is coregulated with Ly-6. The effect on Ly-6 expression of signal transduction through TNF receptors, functioning as pivotal regulators of angiogenesis was therefore studied. It was found that TNFalpha and more so antibodies against Fas down-regulate expression levels of Ly-6. This down-regulation seemed to be selective as expression levels of CD44 were not affected by this treatment.
