WebEpigenetic regulation of the HIV promoter in the 5′ long terminal repeat of HIV-1 via histone protein modifications and the presence of inhibitory nucleosomes play a critical role in the establishment, maintenance, and reactivation of HIV latency. Recent reports have shed further light on how HIV latency might be epigenetically regulated. WebJun 26, 2009 · Cytosine methylation contributes to HIV-1 latency in a polyclonal cell population. To confirm that cytosine methylation is regularly associated with HIV-1 latency, a polyclonal population of latently infected Jurkat T cells was generated by infection with virus produced from the R7/E − /GFP clone.

Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence.

Typically, this group is added to specific places on the DNA, where it blocks the proteins that attach to DNA to … See more DNA wraps around proteins called histones. When histones are tightly packed together, proteins that ‘read’ the gene cannot access the DNA as easily, so the gene is turned “off.” When histones are loosely packed, more … See more Your DNA is used as instructions for making coding and non-coding RNA.
