title: Photodynamic effects of meso-tetra (4-sulfonatophenyl)porphine on human leukemia cells HEL and HL60, human lymphocytes and bone marrow progenitor cells.
abstract: Meso-tetra(4-sulfonatophenyl)porphine (TPPS4), in combination with a light dose of 14 J cm-2, has a profound negative effect on the proliferation and viability of leukemia cells HL60 (human promyelocytic leukemia) and HEL (human erythroleukemia), the viability of normal lymphocytes and the colony-forming activity of human bone marrow progenitor cells. However, normal leukocytes (monocytes, granulocytes) are, to a large extent, resistant to photodynamic treatment (PDT). Whilst DNA fragmentation suggesting apoptosis is induced in HL60 cells, accumulation in the interphase of the cell cycle (G0/G1, G2/M) is mainly operative in the TPPS4-mediated PDT of HEL cells. The "dark" effect of TPPS4 on the cell viability is below 15% up to a concentration of 40 microM.
