title: Role of oxygen on growth rate and gene activity in cultured chick-embryo heart cells.
abstract: Environmental oxygen is shown to have a regulatory role in growth rate and the mechanism of gene de-repression in chick-embryo heart cells; it modulates the intracellular concentration of polyamines, and this appears to be closely related to histone acetylation.
