β-Ele and cisplatin synergistically suppressed the growth of xenograft tumor and induced apoptosis in nude mice. a Tumor volumes were measured once every 3 days from day 0 to day 27 in each group of mice. b Tumor weight was measured at day 27 following treatment in each group of mice. c The xenograft tumors derived from Tca-8113-CDDP cells, after mice sacrificed at day 27. d TUNEL staining was used to detect the apoptosis in the tumor tissues in each group of mice, Scale bar = 100 μm. *P < 0.05, **P < 0.01, ***P < 0.001.
