OAT transcription and mRNA levels in the two lines were similar, but 3-fold greater immunoreactive OAT protein and enzyme activity were observed for Y79. Characterization of polysome-associated OAT mRNAs indicated that they were translated less efficiently, due to decreased initiation, in RB355. Initiation factor eIF-4E mRNA and protein were reduced in RB355; eIF-4E overexpression in RB355 increased OAT translation and OAT protein to the level observed in Y79.
