Low density lipoprotein (LDL) and high density lipoprotein (HDL) were purified from normal human serum by KBr density gradient centrifugation and gel filtration through Sepharose 4B. LDL reversibly inhibited proliferation of Swiss/3T3 cells, whereas HDL had no inhibitory effect on cell growth. The LDL-induced inhibition was LDL-dose dependent and was reversed by the addition of mevalonate, a product of the reaction of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase (mevalonate: NADP+ oxidoreductase (CoA-acylating), EC 1.1.1.34). These data suggest that a specific reduction in the activity of HMG-CoA reductase produced by the addition of LDL is the main cause of the inhibition of cell proliferation. Studies of the effect of LDL on the cell cycle showed that it inhibited the entry of cells arrested in G0/G1 into the S phase but that it did not affect the transition of cells at the G1/S boundary into the M phase. The cell cycle of 3T3 is arrested solely in G1 by LDL.
