Analisis Filogenetik Gen L1 Human Papillomavirus 16 pada Penderita Kanker Serviks di Bandung

Abstract

Chronic infection with high-risk (hr) human papillomavirus (HPV) can lead to cervical cancer. Various hrHPV genotypes have been identified and HPV genotype 16 is the most common genotypes that infect cervical cancer. HPV L1 fragment can identify the origin of HPV. The purpose of this study was to explore the origins of HPV-16 by making a phylogenetic tree. This study used analytical descriptive method and was was conducted at the Laboratory of Molecular Genetics, Health Research Unit, Faculty of Medicine, Universitas Padjadjaran Bandung in the period of February to August 2013. Biopsy from cervical cancer patient was donated by the Department of Obstetrics, Faculty of Medicine, Universitas Padjadjaran, Bandung. Isolation of DNA was prepared from tissue biopsies of cervical cancer and L1 fragment was amplified with the specific primer. Infection with HPV-16 was confirmed by Linear Array test (Roche) design. The sequence then was constructed using the phylogenetic program (MEGA5). Results showed that the isolate from patient with cervical cancer from Bandung was in one subgroup with HPV from Asia and East Asia. In conclusion, cluster HPV of Bandung is in the same strain as the strain in Asia and East Asia
