Figure 5From: Expression of verotoxin-1 receptor Gb3 in breast cancer tissue and verotoxin-1 signal transduction to apoptosis Relative caspase-3, -8 and -9 enzyme activities of T47D cells incubated for 24 h with verotoxin-1 with or without 2 μmol/L PPMP compared to untreated control (activity set to 1). Significant differences (p < 0.05) compared to untreated control are marked with *.Back to article page
