Changes in plasma dolichol levels, transport, and hepatic delivery during rat liver regeneration.

During the proliferative process that follows partial hepatectomy in the rat, the dolichol content increases in both plasma and liver. Its transport in the blood by lipoproteins also changes. The difference in the distribution of dolichols of various chain lengths in plasma and in the liver is further enhanced during liver regeneration. The dolichol released by perfused liver shows a homologue distribution more similar to that observable in blood than in the liver, thus confirming the importance of the liver as a regulatory site for the blood dolichol supply.
