Abstract:
The effect of sodium butyrate on the nuclear proteins of two Chinese hamster cell lines (V79 and CHO) was studied. Butyrate treatment induces hyperacetylation of core histones in both cell lines, while H1 histone shows a different behavior. In CHO cells H1 is dephosphorylated following butyrate incubation; V79 do not show any change of H1 subtypes. It seems that H1 response to butyrate treatment is cell type dependent. Using silver staining a group of proteins that could be present in vivo in the nucleo-protein complex was also detected.
