Murine erythroleukemia cells (MELC) are induced to express erythroid differentiation when cultured with hexamethylene bisacetamide (HMBA). Newly synthesized alpha and beta globin mRNA are both relatively stable, half-life (t1/2) greater than 50 hr, early in the course of induced differentiation. In fully induced cells there is a decrease in stability of both newly synthesized alpha and beta globin mRNA. The decay of alpha mRNA is faster, (t 1/2, 10--12 hr) than beta globin mRNA (t1/2, 20--22 hr). Thus, differences in stability of alpha and beta globin mRNA plays a role in determining the ratio of alpha to beta mRNA content in differentiated erythroid cells.
