Abstract EN

It is known that the interleukin-4 receptor α (IL-4Rα) is highly expressed on the surface of various human solid tumors.

We previously designed novel IL-4Rα-lytic hybrid peptide composed of binding peptide to IL-4Rα and cell-lytic peptide and reported that the designed IL-4Rα-lytic hybrid peptide exhibited cytotoxic and antitumor activity both in vitro and in vivo against the human pancreatic cancer cells expressing IL-4Rα.

Here, we evaluated the antitumor activity of the IL-4Rα-lytic hybrid peptide as a novel molecular targeted therapy for human biliary tract cancer (BTC).

The IL-4Rα-lytic hybrid peptide showed cytotoxic activity in six BTC cell lines with a concentration that killed 50% of all cells (IC50) as low as 5 μM.

We also showed that IL-4Rα-lytic hybrid peptide in combination with gemcitabine exhibited synergistic cytotoxic activity in vitro.

In addition, intravenous administration of IL-4Rα-lytic hybrid peptide significantly inhibited tumor growth in a xenograft model of human BTC in vivo.

Taken together, these results indicated that the IL-4Rα-lytic hybrid peptide is a potent agent that might provide a novel therapy for patients with BTC.
