Moreover, MSNs loaded with emtansine (also named DM1) and surface-decorated with dopamine and a polyethylene glycol, and epithelial cell adhesion molecule (EpCAM) aptamer showed good efficacy against colorectal cancer in xenografts (mice) of the SW480human colorectal cancer cell line, with about 90% tumor volume reduction in two weeks [76]. The gene discussed is EPCAM; the disease is colorectal cancer.
