Topical application of temperature-sensitive caerin 1.1 and 1.9 gel inhibits TC-1 tumor growth in mice.

ABSTRACT: Genital warts, which are one of the most common sexually transmitted diseases (STDs), result from persistent infection with human papillomavirus (HPV), especially subtypes 6 or 11. Topical application of 5% imiquimod cream is currently recommended as a first-line treatment choice for genital warts, but the clearance and patient compliance rates remain less than sufficient. In the current study, we developed a temperature-sensitive gel that contains the host-defense peptides caerin 1.1 and 1.9, which were originally isolated from Australian tree frogs of the genus Litoria. Growth of HPV16 E6/E7-transformed TC-1 cells was inhibited in vitro and in vivo following injection of the tumor with the caerin gel in a TC-1 tumor mouse model. Furthermore, when the caerin gel was t
