Increased apoptosis in tumors after being treated with IP-10 plasmid. Representative sections from LL/2 tumors were presented in normal saline (A), gemcitabine (B), IP-10 plasmid (C) and IP-10 plasmid combined with gemcitabine (D) groups. Bars represented apoptotic index of tumor tissues from LL/2 (open bars) and H22 (solid bars) (E). IP-10 plasmid combined with gemcitabine induced increased apoptosis compared with saline control (**, P < 0.01), also IP-10 plasmid alone or gemcitabine alone versus normal saline (*, P < 0.05).
