So I am trying to brush up on my knowledge of HATs and HDACs.
I am reading the just the 1st paragraph of the background of this study
I remember learning that HATs turn things on on, and HDACs turn things off.
It says that sodium phenylbutyrate (PB), can epigenetically regulate gene expression by inhibiting histone deacetylase.
Does this mean that one of the effects this drug can have is turning the thing that turns things off to produce the effect of turning it back on? Similar to that of a double negative?
