Abstract:
Objective To observe the effects of different doses of Sappan Lignum and Chuanxiong Rhizoma on tumor stem cells marker ABCG2 in vivo. Methods Sphere cells obtained from serum culture were inoculated in nude mouse armpit, which were randomly divided into 5 groups: control group, Sappan Lignum high- and low-dose groups, and Chuanxiong Rhizoma high- and low-dose groups. Each medication group was given relevant medicine for gavage. 21 days later, inhibition tumor rate and ABCG2 protein and mRNA expression were detected with confocal microscope, Western blot, and RT-PCR. Results The sphere cells obtained from serum free culture had the abilities of cancer stem cells, such as proliferation, anti-aptosis and high expression of cancer stem cells markers. Chuanxiong Rhizoma high- and low-dose groups could inhibit tumor growth (P<0.05), and the inhibitory rate of Chuanxiong Rhizoma low-dose group was higher than the Chuanxiong Rhizoma high-dose group. Sappan Lignum high- and low-dose groups inhibited tumor growth without statistical significiance (P>0.05). Compared with the control group, Chuanxiong Rhizoma low-dose group could significantly inhibit the expression of resistant protein of ABCG2. Sappan Lignum high- and low-dose groups could not inhibit the protein expression of ABCG2. Each medication group up-regulated the mRNA expression of ABCG2 except for Chuanxiong Rhizoma low-dose group. Conclusion Low dose of Chuanxiong Rhizoma can inhibit the expression of ABCG2 protein levels, which can be the targeting killer for cancer stem cells.
