Abstract:
:Kinetics of extracellular RNA accumulation in culture medium and at the cell surface along with their composition and distribution among cell-free and cell-surface-bound fractions were investigated in mycoplasma-contaminated and mycoplasma-free HeLa cells. It was shown that the mycoplasma infection influenced the concentration and kinetics of accumulation of total extracellular RNA and the distribution of specific RNA fragments among cell-free and cell-surface-bound fractions. Fragments of immature rRNA were found in culture of mycoplasma-infected HeLa cells. The data obtained indicate the existence of selective mechanisms providing binding of RNA with cell surface and their excretion out of cells.
