Az treatment rescued some trafficking and channel function of ΔF508 CFTR at 37°C, but had a lesser effect on internalization of the mutant protein from the cell surface.
Theoretical analyses of the effect of virus transmission mechanisms on epidemics have shown that the reduction in vector density has a lesser effect on the prevalence of nonpersistently transmitted viruses, such as CMV, than on semi-persistent or persistent/circulative viruses (Madden et al. 2000) in agreement with empirical evidence (Perring et al. 1999).
As presented in Figure 1B, the results of the MTT assay reflect those of the PI uptake measurements: vorinostat was as effective in p53− cells as in p53+ cells, whereas entinostat had a lesser effect on the viability of p53− cells.

Overall, we find that varying the amplitude of the threshold heterogeneity by changing ϵ more strongly affects solution numbers when κ is small, and that the value of κ has a significant effect on how many fixed points exist (and a lesser effect on the number of those which are stable).
