Background: Interferon-inducible protein 10 (IP-10) has been reported to show an effective antiviral and antineoplastic role in various murine models.
Aim: To investigate the anti-condyloma acuminatum effect and human papillomavirus (HPV)-inhibiting efficacy of a recombinant plasmid encoding IP-10 in vitro.
Methods: A recombinant plasmid DNA carrying IP-10 cDNA was constructed. Condyloma acuminatum tissue particles were transfected with IP-10 and examined for apoptosis by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining and flow cytometry techniques. Relative real-time polymerase chain reaction (PCR) was used to validate the HPV inhibited level of the treatment groups. Immunohistochemistry was used to determine the IP-10 expression on condyloma acuminatum tissues.
Results: Transfected IP-10 was expressed mainly in the cytoplasm of the condyloma acuminatum tissues. Plentiful apoptosis was observed in condyloma acuminatum tissues transfected with IP-10. In addition, HPV expression was lower in IP-10-treated tissues than in control tissues.
Conclusions: These observations suggest that IP-10 has strong anti-condyloma acuminatum effects, inducing apoptosis and inhibiting HPV, and therefore may be a novel and potentially effective therapy for condyloma acuminatum.
