Abstract
Intimal sterol synthesis was examined in isolated human arterial segments obtained at surgery or at postmortem examination. The tissues were incubated with acetate-1-14C and mevalonate-2-14C and the incorporation of these precursors into sterols was determined. Intimal sterols were isolated by multiple chromatographic techniques and purified by bromination and oxidation procedures. The results indicate that the arterial intima can incorporate acetate and mevalonate into cholesterol, cholestanol, and squalene. Cholestanol was the major sterol synthesized by the arterial wall, but cholesterol production was also consistently observed. The findings suggest that local synthesis is a potential source of sterol accumulation within the arterial wall.
