Ac-H4K16 in control males strongly localises to nuclear foci the X chromosome and, in both sexes, lower signal intensity is observed throughout the nucleus autosomes. They usually dimerize once bound to their steroid ligand and if two receptor types e.

The results of these experiments appeared to negate the necessity for a direct genetic effect on sexual differentiation of non-gonadal tissues and because it is easier to experimentally manipulate hormonal influences than to alter gene expression, much more has been discovered about the hormonal than genetic control of brain sexual differentiation.

Used in adhesives, aerosols, coating on paper. This pathway appears to be physiologically important because inhibition of PGE 2 synthesis with indomethacin in neonatal male rats reduces dendritic spine density and also male sexual behaviour in adulthood. If neonatal steroids alter neuronal survival, growth and connections, thus inducing neuronal sexual dimorphism, it would reasonable to assume that neurotransmitter activity could also be sexually differentiated.
