dna radioactivity and autoradiographic studies with the use of [ 3h ] thymidine showed a marked inhibition of dna synthesis ( twofold to threefold ) in the neoplastic cell nuclei following a concomitant administration of vitamin a ( retinol ) and mca ( 12 % ) as compared to the dna synthesis following administration of mca alone ( 31 % ) ( p less than .001 ) .
