Native single molecule sequencing and de novo assembly of Hepatitis B Virus to detect 5mCpG
Methylation of Hepatitis B Virus (HBV) DNA in a CpG context (5mCpG) can alter the expression patterns of viral genes related to infection and cellular transformation. Moreover, it may also provide clues to why certain infections are cleared, or persist with or without progression to cancer. The detection of 5mCpG often requires techniques that damage DNA or introduce bias through a myriad of limitations. Therefore, we developed a method for the detection of 5mCpG on the HBV genome that does not rely on bisulfite conversion or PCR. Moreover, using the developed technique, we have provided the first de novo assembly of native HBV DNA, as well as the first landscape of 5mCpG from native HBV sequences Overall design: PHH were isolated from halthy liver tissue and plated before HBV infection with different genotypes. Also investigated fine needle biopsys for HBV DNA.
