The Biology of Oncogenic Viruses

New approaches are explored for historians, by 19 eminent writers, in 21 chapters of timely information. The historiography of ideas in medicine, as one aspect, notes that the historian of science is concerned with the thoughts that refer to facts and theories, be they true or not; whereas the scientist is concerned with facts and theories, asking whether they are true or not. Most of the metho...

Oncogenic viruses and hepatocellular carcinoma.

About 80% of hepatocellular carcinoma (HCC) is caused by hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infections especially in the setting of established cirrhosis or advanced fibrosis, making HCC prevention a major goal of antiviral therapy. HCC tumors are highly complex and heterogeneous resulting from the aberrant function of multiple molecular pathways. The roles of HCV or HBV in ...

An Enzymatic Function Associated with Transformation of Fibroblasts by Oncogenic Viruses

Chick, hamster, mouse, and rat embryo fibroblast cultures, transformed by either DNA or RNA viruses, show fibrinolytic activity under suitable conditions of growth and in appropriate media; normal counterpart cultures do not. The fibrinolysin is produced by the interaction of two protein factors: one of these, a cell factor, is released by transformed cells and accumulates in the medium when cu...

Fibrinolysis Associated with Oncogenic Transformation

Fetal bovine and dog serum were selectively freed of plasminogen by affinity chromatography. The resulting serum as well as native and reconstituted serum (obtained by the addition of purified plasminogen to the plasminogen-depleted serum) were used to examine the role of plasminogen in (a) growth of normal and SV-40-transformed hamster embryo fibroblasts in liquid medium, (b) growth of SV-40-t...
