Expression of mXpr1 protects SY5Y cells from XMRV-induced apoptosis. SY5Y cells transduced with retroviral vectors encoding the indicated Xpr1 proteins or the empty vector were exposed to medium containing the indicated retroviruses or fresh medium only (mock), and the percentages of apoptotic cells were measured 3 days later. Results are means ± SD from two (empty vector and human Xpr1) or three (mouse Xpr1) experiments.
