[Cyclic AMP and cyclic GMP level in cells of spontaneously aborted fetuses with trisomic and triploid karyotypes]

Contents of intracellular cAMP and cGMP were studied in cultivated fibroblasts from 4 spontaneous abortuses with trisomy 7 and trisomy 9 as well as in 4 triploid cell strains. Six diploid cell strains from medical abortuses were used as controls. Distinct increase in cAMP content both calculated per I mg of cell protein or per a cell was found in trisomic strains, whereas the cAMP content increase in triploid strains was detected only per a cell. The data obtained suggest that functions of membrane complexes were impaired in the cells with anomalous karyotype.
