Qing-Kai-Ling Injection Acts Better Than Shen-Fu Injection in Enhancing the Antitumor Effect of Gefitinib in Resistant Non-Small Cell Lung Cancer Models
Figure 5
QKL oral solution, not SF decoction, and gefitinib synergistically inhibited the tumor growth via regulating p-AKT in vivo. (a) The tumor growth curve showing the anticancer effect of gefitinib and QKL/SF in H1975 xenograft transplanted nude mice. (b) The tumor weight showing the anticancer effect of gefitinib and QKL/SF in H1975 xenograft transplanted nude mice at day 19. (c) The statistics of EGFR, p-EGFR, AKT, p-AKT, ERK, and p-ERK protein expression in H1975 xenograft transplanted nude mice. (d) Immunohistochemical staining showing the effects of gefitinib and QKL/SF on the expression of EGFR, p-EGFR, AKT, p-AKT, ERK, and p-ERK protein (×400 magnifications). vs. control group. ▲ vs. gefitinib group. QKL, Qing-kai-ling oral solution; SF, Shen-fu decoction.
