Cancer cell cytotoxicity
WebImportantly, PDAC-derived exosomes induce a dose-dependent inhibition of PDAC serum-mediated complement-dependent cytotoxicity towards cancer cells. In summary, we provide evidence that exosomes display a large repertoire of tumor antigens that induce autoantibodies and exert a decoy function against complement-mediated cytotoxicity. WebMaterial and methods: Breast, lung, cervical, and liver cancer cell lines were exposed to the extracts, and viability was assessed using the Sulforhodamine B method. P. pinnata and S. longipedunculata with significant cytotoxicity were selected for in vivo tests. The acute oral toxicity of these extracts was assessed using BALB/c mice.
