SR-BI-directed HDL-cholesteryl ester hydrolysis
We have examined the metabolic fate of HDL cholesteryl ester (CE) delivered to cells expressing scavenger receptor class B type I (SR-BI). Comparison of SR-BI with a related class B scavenger receptor, CD36, showed a greater uptake and a more rapid and ...

Iterative focused screening with biological fingerprints identifies selective Asc-1 inhibitors distinct from traditional high throughput screening [PDF]
N-methyl-d-aspartate receptors (NMDARs) mediate glutamatergic signaling that is critical to cognitive processes in the central nervous system, and NMDAR hypofunction is thought to contribute to cognitive impairment observed in both schizophrenia and ...

17β-Estradiol promotes the up-regulation of SR-BII in HepG2 cells and in rat livers
The scavenger receptor class B type I (SR-BI) binds to HDL and mediates the selective uptake of cholesterol esters from HDL to cells. SR-BII is an alternatively spliced product of the SR-BI gene that only differs in the C-terminal cytoplasmic domain ...

High density lipoprotein metabolism in low density lipoprotein receptor-deficient mice1[S]
The LDL receptor (LDLR) and scavenger receptor class B type I (SR-BI) play physiological roles in LDL and HDL metabolism in vivo. In this study, we explored HDL metabolism in LDLR-deficient mice in comparison with WT littermates.

Selective uptake of cholesteryl esters from low density lipoproteins in vitro and in vivo
Evidence for the direct uptake (“selective uptake”) of cholesteryl esters (CE) from low density lipoproteins (LDL) by perfused luteinized rat ovaries (Azhar, S., A. Cooper, L. Tsai, W. Maffe, and E. Reaven. 1988. J. Lipid Res.

Inflammation mobilizes copper metabolism to promote colon tumorigenesis via an IL-17-STEAP4-XIAP axis. [PDF]
Copper levels are known to be elevated in inflamed and malignant tissues. But the mechanism underlying this selective enrichment has been elusive. In this study, we report a axis by which inflammatory cytokines, such as IL-17, drive cellular copper ...

Regulation of the selective uptake of high density lipoprotein-associated cholesteryl esters
We have previously shown in rats that the cholesteryl ester component of high density lipoproteins (HDL) is taken up at a greater fractional rate than is the apolipoprotein A-I component (selective uptake) by liver and steroidogenic tissues.

Scavenger receptor class B type I (SR-BI) mediates the selective uptake of HDL cholesteryl esters (CEs) by the liver. Hepatic lipase (HL) promotes this lipid uptake independent from lipolysis.
