Nuclear Phosphatidylcholine and Sphingomyelin Metabolism of Thyroid Cells Changes during Stratospheric Balloon Flight
Figure 2
Neutral-sphingomyelinase, phosphatidylcholine-specific phospholipase C, sphingomyelin-synthase, and reverse sphingomyelin-synthase activities in purified nuclei of FRTL-5 cell cultured in the presence of TSH (TSH+). Data are expressed as pmol/mg protein/min and are the mean S.D. of three samples performed in duplicate. versus control sample.
