Possible alterations in the population of poly(A)(+)mRNA during ageing were investigated by translation in vitro of poly(A)(+)mRNA from the liver, kidney and brain of male ddY mice of different ages. [35S]Methionine-labeled translation products were analysed by two-dimensional polyacrylamide gel electrophoresis followed by fluorography. A protein product with a molecular weight of 30 000 and isoelectric point of 6.5 was reproducibly observed only in the fluorograms of translation products of poly(a)(+)mRNA derived from the livers of senescent mice (24.5 months old). However, no age-related change was detected in the translation products of the kidney and brain. These results suggest that gene expression in liver cells changes at the level of the population of cytoplasmic poly(A)(+)mRNA during ageing.
