2,4-Dichlorophenoxyacetic acid action on in vitro protein synthesis and its relation to polyamines

The effect of 2,4-dichlorophenoxyacetic acid (2,4-D) on the in vitro synthesis of proteins was studied in Chinese hamster ovary cells. A remarkable inhibition of the synthesis of proteins was observed when cells grew for 24 h in presence of 1 mM 2,4-D. This effect was reversed by adding 0.1 mM of the three polyamines (putrescine, spermidine and spermine) to the cultured cells. The mRNA is not altered, indicating that the 2,4-D action is located at a different locus, which may be the ribosomes. From these studies, one can speculate that the alterations in the protein synthesis may be a consequence of the effect of 2,4-D on the polyamine metabolism.
