Hexamethylbisacetamide Remodels the Human Immunodeficiency Virus Type 1 (HIV-1) Promoter and Induces Tat-Independent HIV-1 Expression but Blunts Cell Activation

Abstract excerpt

Hexamethylbisacetamide (HMBA) induces human immunodeficiency virus type 1 (HIV-1) gene expression in latently infected T-cell and monocytoid cell lines. We find that HMBA activation of viral expression is Tat independent but, like Tat, increases the efficiency of elongation of the HIV-1 promoter (long terminal repeat [LTR]) transcripts. Further, exposure to HMBA induces chromatin remodeling at nucleosome 1...
