It is extremely difficult, if not impossible, to reconcile the conflicting claims of those who have treated different cells and tissues with exogenous RNA. Some authors (e.g. Niu, Cordova & Niu, 1961; Niu, Cordova & Radbill, 1962) maintain that RNA extracts alter the course of cell differentiation to conform in morphological terms to the source of the RNA; in the same vein, Amos, Askonas & Soeiro (1964) have shown that, under certain conditions, RNA from mouse and bacterial cells can stimulate chick embryo fibroblasts to synthesize protein related antigenically to the origin of the RNA. Shepley, Ambrose & Kirby (1965), however, obtained stimulation of growth with permanent morphological changes in baby hamster kidney fibroblasts by the addition of RNA from a variety of sources.

Rna Extract

Naive rats given intraperitoneal injections of an extract prepared from the brains of either trained or untrained donor rats learned a position discrimination task in simple parallel alley runways significantly faster than original (uninjected) donor rats. Specific interanimal transfer, however, was not demonstrated as there was no statistically reliable difference between recipients of “trained brain” vs “untrained brain” extracts.

Rna Extract

RNA extracted from trained and untrained (control) rats did not demonstrate statistically significant transfer of learning effects when injected intraperitoneally into naive recipient rats. Since the direction of the results consistently favored the “trained RNA extract” recipient, it is suggested that future investigation of biochemical transfer utilize more rigorous training for donor animals and larger RNA dosage levels for injections of recipient animals.
