Generation of a DNA microarray for determination of E6 natural variants of human papillomavirus type 16.

2003

Infection with high-risk types of human papillomavirus (HPV) is necessary for the development of cervical cancer. However, the majority of the HPV infections are efficiently cleared by the immune system and only a minority persist and induce the development of malignant lesions. Several studies provided evidence that intratype genetic variations are implicated in determining the clinical outcome of HPV infections. In this study, we describe a DNA chip based on arrayed primer extension (APEX) for the analysis of the natural variants of HPV16, the most frequently detected type in cervical cancer world-wide. We show that HPV16 E6 variants are detected efficiently by APEX. In addition, APEX is …
