ζ-Stat (0.1-20 μM) shows only 13% inhibition on PKC-Ι at 20 μM, but shows a significant inhibition on PKC-ζ as 51% at 5 μM level[1].ζ-Stat (0.1-10 μM; 3 d) significantly decreases cell proliferation of SK-MEL-2 and MeWo upon increasing the concentrations[1].ζ-Stat (7 or 10 μM; 24-72?h) and 5-FU in combination is able to decrease the viability of LoVo CRC cells by more than 75%[2].ζ-Stat (5 μM; 3 d) shows a significant diminution of phosphorylated, total PKC-ζ, Bcl-2 and PARP levels, and increases Caspase-3 and cleaved-PARP levels in SK-MEL-2 and MeWo cells[1].ζ-Stat (5 μM; 1-10 h) does not show significant cytotoxicity on MEL-F-NEO, SK-MEL-2 and MeWo cells[1].
