Abstract:
Objective To investigate the antitumor mechanism of astragaloside combine with cetuximab on the colon cancer cell line RKO of EGFR over expression through cell proliferation and autophagy. Methods The cell proliferation of colon cancer cell line RKO intervened by astragaloside with or without cetuximab was detected by 4- methyl- teerazolium (MTT). The expressive changes for protein of EGFR 、P62 and LC3 in RKO cells was detected by western bolt. Results MTT showed that 100 ug/mL astragaloside combined with 120 ug/mL cetuximab had significantly inhibiting effect on RKO cells of EGFR expression. Western blot showed that astragaloside can affect the expression of P62 and LC3 to suppress the occurrence ofautophagy. Conclusion In the vitro studies showed that astragalosidecan enhance the antitumor cell proliferation of cetuximab through inhibit autophagy in the treatment of colon cancer.
