VIM and cancer: Vimentin expression increased the migration and invasion of cancer cells. Preparing artemisinin (which inhibits vimentin expression) as a capping agent for the NPs loaded with drugs can be useful.Fibroblast activation protein is overexpressed in the stroma. N-(4-quinolinoyl)-Gly-(2-cyanopyrrolidine)-capping NPs inhibit FAPs overexpression with the active drug, which may be useful to regulate stroma
