Abstract/OtherAbstract:
This study aimed to investigate the resistance mechanism of C6/36 cells to Cyt1Aa6 protein under selection pressure. Receptor binding properties of Cyt1Aa6 toward sensitive and resistant C6/36 cells were investigated. More sensitive cells were detected with goat-anti-rabbit-FITC-labeled antibody, and the quantity of in vitro activated Cyt1Aa6 toxin bound to resistant cells was greatly reduced. Ligand western blot assays showed that disappearance of the 26 kDa protein and weakness of the positive bands of 68 kDa from resistant cells might lead to the resistance of C6/36 cells to Cyt1Aa6 toxin. The resistance of C6/36 cells was detected under selection in vitro-activated Cytl1Aa6 toxin. Receptor binding demonstrated that reduced Cyt1Aa6 bound to resistant cells, which might be closely related to the disappearance and weakness of some proteins. The results presented here are the first to demonstrate that Cyt1Aa protein, a uniquely characteristic toxin, induced resistance at the cellular level. It might be attributed to the change of receptors.
