Fig. 4From: A short peptide derived from pigment epithelial-derived factor exhibits an angioinhibitory effectThe 7-mer induces JNK signaling to trigger p53/bax/p21Waf1 expression in RPMI8226 cells. a and b Cell treatments were as described in Fig. 3. Cell lysates were then prepared for western blot analysis of p53, Bax, and p21. Representative blots and densitometric analyses from three independent experiments are shown. *P < 0.001 versus 7-mer-treated cellsBack to article page
