Fig. 1. Effects of dihydroartemisinin (DHA) and holotransferrin (TF) on proliferation of C6 cells.

DHA and TF efficacy in the inhibition of C6 cell proliferation were measured by MTT assay after 12 or 24 hrs from administration. It is shown that the inhibition efficacy of the combination of DHA and TF depends on exposure time as well as the concentration. P-value by paired t-test of DHA and DHA+TF.
