Figure Lengend Snippet: Inhibition of protein biosynthesis and induction of apoptosis in prostate cancer cells after treatment with EGF-PE24mutΔREDLK and SO1861. (A) Protein biosynthesis inhibition was demonstrated by puromycin Western Blot after 48 h in LNCaP and after 72 h in DU145 and PC-3 cells. EGFR-negative CHO cells remained unaffected. (B) Induction of apoptosis after combination treatment was marked by poly (ADP-ribose) polymerase (PARP) cleavage and caspase-3 activation. Western blots after 48 or 72 h of single or combination treatment of LNCaP (48 h), DU145, PC-3 or CHO cells (all 72 h) with 1.0 µg/ml SO1861 and 2.5 nM EGF-PE24mutΔREDLK. β-actin was used as a loading control. * As CHO cells are not of human origin, detection of human Caspase-3 was not possible in this cell line. Abbreviation: M, protein marker.
