Cultivation with 4-8 mumol/l hypericin (specific proteinkinase C inhibitor) activated by light induced high inhibition of the rate of HL-60 cell growth. When hypericin treated cells were not exposed to light growth inhibition was insignificant. Cultivation with light activated hypericin in concentration 16 mumol/l slightly inhibited growth rate of AtT20/D16v-F2 cells. AtT20/D16v-F2 cells did not proliferate in presence of light activated 32 mumol/l hypericin. Evidence of apoptosis was found in HL-60 cells treated with 1-8 mumol/l light activated hypericin, with maximum of apoptotic cells detected after 8 mumol/l light activated hypericin. Light activated hypericin induces both apoptosis and necrosis in dose and time dependent manners in HL-60 cells, but causes only necrosis in AtT20/D16v-F2 cells.
