This review focuses on the function and subcellular location of five key aminopeptidases (aminopeptidase N, leucine aminopeptidase, puromycin-sensitive aminopeptidase, leukotriene A4 hydrolase and endoplasmic reticulum aminopeptidase 1/2) and their association with different diseases, in particular cancer and their current position as target for therapeutic intervention by aminopeptidase inhibitors.
The potential efficacy of hlFVII-LDP-AE for cancer therapy was examined in vitro by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays and in vivo with a BALB/c nude mouse xenograft model of the human lung cancer line NCI-H292. hlFVII-LDP-AE caused chromatin condensation and cleavage of genomic DNA in NCI-H292 cells.
