FIG. 3.
Lower glucosamine incorporation into macromolecules observed in cells expressing HCV replicons. Huh7 and FCA4 cells were grown in 1 ml of medium containing [14C]glucosamine (1 μCi/ml) (A) or [35S]methionine and [35S]cysteine (20 μCi/ml) (B). At the indicated times, the trichloroacetic acid-precipitable radioactivity was determined in Huh7 (▪) and FCA4 (•) cells.
