RGD and NGR modified TRAIL protein exhibited potent anti-metastasis effects on TRAIL-insensitive cancer cells in vitro and in vivo.
    Amino acids, 2017, Volume: 49, Issue:5

    The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been considered to be a promising anti-tumor agent since the discovery of TRAIL-mediated apoptosis specifically on cancer cells. However, TRAIL resistance of tumor cells and patients remains to be an insurmountable obstacle for its clinical application. Here, we expressed TRAIL-related recombinant protein RGD-TRAIL, TRAIL-NGR, and RGD-TRAIL-NGR by fusing tumor targeting peptides RGD and (or) NGR at the N-terminus and C-terminus, respectively, to not only induce apoptosis of cancer cells but also inhibit metastasis. The fusion proteins possessed potent cytotoxicity with approximative IC50 in H460 and A549 cells, while TRAIL-NGR and RGD-TRAIL-NGR appeared to be more effective in HT1080 and PANC-1 cells which were relatively insensitive to TRAIL. A low concentration of fusion proteins, especially RGD-TRAIL-NGR, could inhibit migration of A549 and HT1080 cells in vitro and lung metastasis in HT1080

Design, synthesis, and activity evaluation of a new 5-fluorouracil prodrug containing an Asn-Gly-Arg(NO2)COOCH3 tripeptide.
    Protein and peptide letters, 2012, Volume: 19, Issue:10

    Aminopeptidase N (APN/CD13) of the M1 family is a broad specificity enzyme that is intimately involved in tumor angiogenesis and metastasis. Asparagine-glycine-arginine (NGR) is a tumor-homing tripeptide, which can selectively combine with APN/CD13 that is overexpressed on the surface of some tumor cells. Various anti-tumor drugs can be conjugated to NGR to improve selectivity, efficacy, and to decrease drug toxicity. In this study, a tripeptide NGR(NO2) was synthesized and conjugated with 5-fluorouracil. The anti-tumor activities of this new prodrug were evaluated in vivo. More significant anti-tumor effects were observed over the parent 5-fluorouracil.
