Antitumor activity of apoptotic nuclease TBN1 from L. esculentum
Original language description
Nuclease from tomato (TBN1) was produced by in planta biotechnology purified and tested for its anticarcinogenic properties. The nuclease was cytostatic after its intratumoral administration to nude mice bearing human melanoma or prostate carcinoma or after tumor targeting by TBN1 administration intravenously as conjugate with polyethylene glycol (PEG). Inhibitory effects of TBN1 on tumor growth were comparable to effects of bovine seminal RNase (BS-RNase), but the inhibition was reached at about ten times lower protein concentration. Simultaneously, TBN1 exhibited a lower degree of embryotoxicity compared to BS-RNAse and other nucleases. TBN1 showed significant stability in vivo, because it was readily detected after its administration intratumorallyor intravenously by the fluorescence methods. Intravenous administration of TBN1-PEG caused significant inhibition of tumor proliferation without obvious degenerative changes, while direct administration of TBN1 into melanoma tumors led t
