    Abstract:
    The effects of delta 9-tetrahydrocannabinol (THC) treatment on acid soluble pools of uridine nucleoside and nucleotides were investigated in Tetrahymena pyriformis and in isolated mouse lymphocytes and spermatogenic cells. In THC treated Tetrahymena and mouse lymphocytes the uptake of labelled precursor into acid soluble pools of uridine nucleoside and nucleotides fluctuated, whereas in pachytene spermatocytes and round spermatid cells the labelled pool was reduced. The reduction in the labelled pool measured in mouse spermatogenic cells was attributed primarily to a reduction in radioactively labelled uridine nucleoside. Treatment of Tetrahymena in high concentrations of THC (960 and 3,200 microM) resulted in an increase of labelled uridine nucleoside and a reduction in the amount of labelled uridine nucleotides. Expansion of the acid soluble pool with radioactive uridine resulted in small differences in labelled nucleoside and nucleotides in control and THC treated Tetrahymena and mouse lymphocytes. The results are discussed in terms of the effects of THC on macromolecular synthesis in various cellular systems.
