title: Membrane fatty acid changes during the cell cycle of CV-1 cells.
abstract: Monolayers of CV-1 cells were synchronized at the G1/S boundary of the cell cycle by a 24-h 2 mM thymidine blockade. Uptake of tritiated thymidine indicated that the peak DNA synthesis occurred 6-8 h after release from the block and that cell cycle time was 18-20 h. The fatty acid composition of phospholipids extracted from cells at 0, 7, and 18 h postblockade was measured by gas chromatography. The results indicate cyclic changes in membrane fatty acids with a significant increase in long-chain polyunsaturated fatty acids during the DNA synthesis phase (S phase) of the cell cycle.
