Fig. 8From: Phage display screening identifies a novel peptide to suppress ovarian cancer cells in vitro and in vivo in mouse modelsEffect of Peptide 1 treatment on induction of apoptosis in a nude mouse intraperitoneal tumorigenicity model (×400). Mouse tumor tissues were dissected and immunostained for TUNEL assay. Stained tissue sections were reviewed and scored (see Method section). a Representative images of tumor sections examined by TUNEL assay. b The apoptotic index significantly increased in mouse tumor tissues of Peptide 1 group tumor sections compared to those of the negative control peptide and parental group tumor sections. The data are presented as the average number of apoptotic index ± SD. *P < 0.05 versus the negative control peptide and parental group; #P > 0.05 versus parental groupBack to article page
