Title: Inhibition of DNA replication and growth of several human and murine neoplastic cells by aphidicolin without detectable effect upon synthesis of immunoglobulins and HLA antigens.

The concentration of aphidicolin causing 50% inhibition of DNA synthesis in all of the tested neoplastic cell lines is similar to that necessary to inhibit DNA synthesis in HeLa cells by 50%. The mechanism of inhibition of DNA synthesis in neoplastic cells is again due to the inhibition of DNA polymerase alpha by aphidicolin. Aphidicolin at a concentration 100 times higher than that causing 50% inhibition of DNA synthesis and cell growth had no effect on total protein synthesis, on the secretion of immunoglobulins, or on the expression of HLA antigens which are involved in relevant phenomena of the immune response.Read More
