Increased flux of the plant sterols campesterol and sitosterol across a disrupted blood brain barrier

Steroids, 2015
The intact blood-brain barrier in mammalians prevents exchange of cholesterol loaden particles between periphery and brain and thus nearly all cholesterol in this organ originates from de novo synthesis. Dietary cholesterol homologues from plants, campesterol and sitosterol, are known to get enriched to some extent in the mammalian brain.

Studies on the mechanism of high intestinal absorption of cholesterol and campesterol in high-responding rhesus monkeys

Atherosclerosis, 1988
To understand better the mechanism of higher absorption of cholesterol and campesterol in high-responding than in low-responding rhesus monkeys, we measured the concentrations of the two sterols in the micellar fraction isolated from small intestinal content, and also determined their rates of esterification by cholesterol esterase prepared from the ...

24‐Methylenecholesterol: Isolation and identification as an intermediate in the conversion of campesterol to cholesterol in the tobacco hornworm

Lipids, 1972
Abstract24‐Methylenecholesterol was positively identified as an intermediate in the dealkylation and the conversion of campesterol to cholesterol in the tobacco hornworm,Manduca sexta (L.). Biochemical and nutritional studies with3H‐labeled campesterol and 24‐methyl‐enecholesterol indicated that the conversion of campesterol to cholesterol in this ...

The Arabidopsis dwarf1 mutant is defective in the conversion of 24-methylenecholesterol to campesterol in brassinosteroid biosynthesis.

Plant physiology, 1999
Since the isolation and characterization of dwarf1-1 (dwf1-1) from a T-DNA insertion mutant population, phenotypically similar mutants, including deetiolated2 (det2), constitutive photomorphogenesis and dwarfism (cpd), brassinosteroid insensitive1 (bri1), and dwf4, have been reported to be defective in either the biosynthesis or the perception of ...

Measurement variability of plasma β-sitosterol and campesterol, two new biomarkers for cancer prevention

European Journal of Cancer Prevention, 2001
Phytosterols are plant sterols that are structurally similar to cholesterol and are characterized by anti-carcinogenic and anti-atherogenic properties. Beta-sitosterol and campesterol are the predominant phytosterols in blood. The present study aimed to analyse the reproducibility and overtime reliability of plasma beta-sitosterol and campesterol ...
