Effect of expression of SPF on the incorporation of
[14C]acetate into cellular sterols in McARH7777 cells.
McARH7777 cells were transiently transfected by cDNA plasmids [mock
(□), rat SPF (░⃞), rat α-TTP (■)],
and after 48 h, [14C]acetate was added to a final
concentration of 28 μCi/ml, and the cells were incubated for 3
h. Radiolabeled sterols were extracted and resolved by TLC, and the
incorporated radioactivities of squalene, lanosterol, cholesterol, and
triacylglycerol were measured. Each point denotes the mean ± SE
of three separate experiments.
