Distinct epigenetic profiles in children with perinatally-acquired HIV on antiretroviral therapy.

ABSTRACT: Perinatally-acquired HIV has persistent effects on long-term health outcomes, even after early treatment. We hypothesize that epigenetic indicators, such as DNA methylation, may elucidate cellular processes that explain these effects. Here, we compared DNA methylation profiles in whole blood from 120 HIV-infected children on antiretroviral therapy (ART) and 60 frequency age-matched HIV-uninfected children aged 4-9 years in Johannesburg, South Africa. Using an individual CpG site approach, we found 1,309 differentially-methylated (DM) CpG sites between groups, including 1,271 CpG sites that were hyper-methylated in the HIV-infected group and 38 CpG sites that were hypo-methylated in the HIV-infected group. Six hyper-methylated CpG sites were in EBF4, which codes for a transcription factor i
