| Abstract: | Objective To study the effects of alkaloid of Solanum nigrum on membrane fluidity and membrane protein level of tumor cells in H_ 22 tumor-bearing mice (H_ 22 mice). Methods The membrane fluidity of tumor cells in H_ 22 mice was observed by DPH fluorescentprobe marker method, and the level of membrane proteins of tumor cells in H_ 22 mice were determined by Coomassie brilliant blue. Results The alkaloid of S. nigrum could make the membrane fluidity decline and the level of membrane proteins of tumor cells in H_ 22 mice decrease. Conclusion The alkaloid of S. nigrum shows the antitumor activity through decreasing the membrane fluidity and the membrane protein level of tumor cells in H_ 22 mice. |
