Objective To study the anti-tumor effects of TM-TNF-α mimic peptide displayed on phages in vivo. Methods Peptides-presenting phages were prepared and their anti-tumor effects were compared. Then, the peptide with the best effect and the suitable concentration was subcutaneously injected on day 3 after H22 tumor cell challenge. The tumor growth was observed. Results TM-TNF-α mimic peptide displayed on phages can dramatically inhibit the growth of tumor (P<0.01) in a dose dependent manner. HE staining show...
