Notes: Summary Increased hexose uptake is a marker for viral transformation, as has been shown in non-human fibroblasts transformed by oncogenic viruses. If this phenomenon is a general expression of viral induced transformation it should also apply on different oncogenic virus-cell systems. Recently two human EBV-negative lymphoma lines were converted to a stable EBV-positive state by infection with EBV. According to their biochemical and biological properties they enable us to study events associated with EBV-transformation. We analysed the uptake of (3H) glucosamine and (3H) 2-deoxy-D-glucose into BJAB and Ramos and their EBV-converted sublines and found a clear increase of the rate of uptake of both sugars in the EBV-positive sublines. Control experiments confirmed that the increased uptake was due to alterations on the level of the hexose membrane carriers and not due to increased metabolism. The observation of increased hexose uptake in the only presently available virus transformed human cell system is a strong argument for the general importance of this transformation-associated membrane change.
