title: [Study of cytoplasmic RNA in tissues of the rat, regenerating liver and in liver of rats with hepatoma PC-1].
abstract: Cytoplasmic RNA of the rat regenerating liver and liver of rats with hepatoma PC-1 is separated into five fractions on the column of kieselgur with methylated albumin (MAK). Studies in the nucleotide composition showed that certain fractions of cytoplasm RNA are ribosomal and messenger RNA. The highest amount of radioactive precursor is incorporated into messenger RNA of the rat regenerating liver and liver of the rats with hepatoma PC-1 which is eluated from the column by 0.2% solution of sodium dodecyl sulphate at 37 degrees C (third fraction). Actinomycin D in doses inhibiting appearance of characteristic proteins in the blood serum of rats with the regenerating liver and heaptoma PC-1 blocks almost completely biosynthesis of ribosomal RNA eluated from the MAK column in the gradient of sodium chloride (second fraction), and that of messenger RNA, eluated by sodium dodecyl-sulphate at 37 degrees C (third fraction).
