Apoptosis
Research by J. Kralova and colleagues in apoptosis provides new insights
August 5th, 2008
"In this study, we provide evidence that photostimulation of various cancer cells preloaded with a new photosensitizing compound, tetrakis-meso-(4-ethyleneglycol-2,3,5,6-tetra. fluorophenyl) porphyrin (PORF-TEG), results in rapid activation of the cell death machinery. PORF-TEG, although primarily localized in lysosomes, induces mitochondria-driven apoptosis," scientists in Prague, Czech Republic report. "The induction of apoptosis is accompanied by immediate and sustained activation of p38 mitogen-activated protein kinase (MAPK) and transient activation of c-Jun N-terminal kinase (JNK). Conversely, the inhibition of p38 by PD 169316 or SB202190 and by the p38a...
