The activity of the mitosis-promoting kinase CDC2-cyclin B is normally suppressed in S phase and G2 by inhibitory phosphorylation at Thr14 and Tyr15. This work explores the possibility that these phosphorylations are responsible for the G2 arrest that occurs in human cells after DNA damage. HeLa cell lines were established in which CDC2AF, a mutant that(More)
It is well known that autophagy, a cellular stress response to degrade damaged components, can be activated by many nanoparticles. We have demonstrated that CdSe/ZnS quantum dots (QDs), which are widely applied in vitro for diagnostics and cellular imaging, can impair synaptic transmission and synaptic plasticity in the dentate gyrus (DG) area, but the(More)
