Abstract

Epstein-Barr virus (EBV) encodes six nuclear transformation-associated proteins that induce extensive changes in cellular gene expression and signaling and induce B-cell transformation. The role of HIF1A in EBV-induced B-cell immortalization has not been previously studied.

Figure 6. Shows a favoring of aerobic glycolysis in the immortalized lymphoblastoid cell lines (LCL) when compared to both CD40+IL4 activated cells and newly Epstein-Barr Virus-infected B-cells. In addition to the increased levels of lactate and pyruvate, increased ROS levels were found in LCL's in comparison to the CD40+IL4 and EBV B-Cell cell lines.
