Fig. 5From: Viral E6 is overexpressed via high viral load in invasive cervical cancer with episomal HPV16Methylation frequency is calculated from all five positions in the promoter as an average. >50% of methylation frequency is regarded as high methylated, 11–50% as medium methylated and <10% as low methylated. The proportions of highly, medium, and low methylation are shown in invasive cervical cancer tissues with integrated, mixed and episomal HPV16Back to article page
