Popis: This paper gives comparative data on the effect of the new antitumor enzyme LO from a Soviet strain Trichoderma harzianum Rifai and from Trichoderma viride from Japan, on DNA and RNA synthesis in human ovarian carcinoma cells (CaOv strain) in culture, and also the results of the action of LO from T. harzianum Rifai on protein synthesis. Specific precursors were added before the end of the incubation time to the samples; /sup 3/H-thymidine as precursor for DNA synthesis, /sup 3/H-uridine as RNA precursor, and /sup 3/H-leucine as protein precursor. The final values of inhibition of DNA and RNA synthesis in the presence of enzyme from both sources are shown to depend in a virtually linear manner on enzyme concentration.
