Fig. 8. Model for regulation of apoptosis by eIF5B in U343 glioblastoma cells.

eIF5B (gray oval) promotes translation of XIAP, Bcl-xL, cIAP1, c-FLIPS, and Nrf2 (green ovals). These, in turn, promote cell survival in the presence of TRAIL by abrogating the effects of reactive oxygen species (ROS) and/or the functions of FADD, caspase-9 (cas-9), and caspase-7 (cas-7). As XIAP, cIAP1, and Bcl-xL all act downstream of mitochondria, eIF5B might also promote resistance to intrinsic apoptosis—for instance, owing to DNA damage from chemotherapy or radiation treatment (represented by the lightning bolt)
