Abstract
AIM: To study the affinities of antagonistic peptides with HAb18G/CD147 on the hepatocellular carcinoma cells.
METHODS: Fluorescence-activated cell sorting analysis(FACS) was used to detect the expression of HAb18G antigen on HHCC and SMMC7721 cells. Antagonistic peptides(APs) AP-1, AP-2 and AP-6 were labelled with biotin at their N-terminals. The binding abilities of APs to HHCC or SMMC7721 cells were determined by FACS and confocal microscope.
RESULTS: HAb18G antigen was highly expressed on the HHCC and SMMC7721 cells. AP-6 has the highest affinity for HHCC and SMMC7721 cells compared with AP-1 and AP-2.
CONCLUSION: Antagonistic peptides of HAb18G/CD147 have high affinities with HAb18G/CD147 on the hepatocellular carcinoma cells.
