    Abstract:
    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.
