... sig-naling for hypoxia was of interest in this studybecause QDs, which are redox-active NPs, can releaseCd2+ and induce the intracellular formation of ROS, and, as such, make good candidates ... resulting in an increase in glucose uptake and an up-regulation of glycolysis[37,38]. In addition, PI3K signaling has been shown tobe involved in the up-regulation of lipogenic enzymes,such as ... forming multiplecytoplasmic LDs (Fig. 1B–D).
