In CHO cell line and primary human diploid fibroblasts culture an incorporation of protein, RNA and DNA biosyntheses precursors was investigated under different conditions of inhibition of translation by cycloheximide (CHM). Both CHO and human fibroblasts transitory treatment by CHM in the serumfree medium resulted in inhibition of protein and DNA syntheses during S-period while RNA synthesis increased up to 130% (CHM concentration from 0.003 to 2 Mg/ml), as well as in Go--an incorporation of 3H-U increased to 200% (CHM concentration-100 Mg/ml). Long-term treatment (48 hours) in the serum-free medium resulted in decreased uptake of 3H-T and 3H-L during first 6 hours of experiment, while incorporation of 3H-U increased to 160%. By 16-th hour of treatment characters of protein, RNA and DNA syntheses came back to control levels.

UI MeSH Term Description Entries
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D003513 Cycloheximide Antibiotic substance isolated from streptomycin-producing strains of Streptomyces griseus. It acts by inhibiting elongation during protein synthesis. Actidione,Cicloheximide
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine). DNA, Double-Stranded,Deoxyribonucleic Acid,ds-DNA,DNA, Double Stranded,Double-Stranded DNA,ds DNA
D005347 Fibroblasts Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules. Fibroblast
D006224 Cricetinae A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS. Cricetus,Hamsters,Hamster
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012313 RNA A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.
