Abstract


Infeksi human papillomavirus (HPV) tipe high risk (hr) yang kronik dapat menyebabkan kanker serviks. Berbagai genotipe hrHPV telah teridentifikasi dan HPV-16 merupakan genotipe yang tersering menginfeksi serviks. Fragmen L1 HPV dapat digunakan untuk mengidentifikasikan asal usul HPV. Tujuan penelitian ini adalah mengeksplorasi asal usul HPV-16 dengan membuat pohon filogenetik. Metode penelitian yang digunakan adalah metode deskriptif analisis. Penelitian dilakukan di Laboratorium Genetika Molekuler Unit Penelitian Kesehatan, Fakultas Kedokteran Universitas Padjadjaran Bandung pada Februari hingga Agustus 2013. Isolat biopsi dari pasien kanker serviks disumbangkan oleh Departemen Kebidanan Fakultas Kedokteran Universitas Padjadjaran, Bandung. Isolasi DNA dibuat dari biopsi jaringan kanker serviks dan fragmen L1 diamplifikasi dengan desain primer sendiri. Infeksi dengan HPV-16 dikonfirmasi dengan Linear Array test (Roche). Sekuens urutan basa kemudian dimasukkan dalam program filogenetik (MEGA5). Hasil konstruksi menunjukkan isolat pasien kanker serviks dari Bandung berada dalam satu subgrup dengan HPV asal Asia dan Asia Timur. Simpulan, cluster HPV Indonesia berada pada galur Asia dan Asia Timur. [MKB. 2015;47(3):174–78]

Phylogenetic Analysis of Human Papillomavirus 16 L1 Gene from Cervical Cancer Patient in 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. [MKB. 2015;47(3):174–78]
