A case report of a ciprofloxacin and simvastatin interaction is presented. The addition of ciprofloxacin to chronic simvastatin therapy led to the development of rhabdomyolysis. As ciprofloxacin is a weak inhibitor of CYP3A4, it is very likely that other mechanisms involving the ATP-binding cassette drug efflux transporter family played a role in this drug interaction.

Studies with ATP-binding cassette transporter (ABCA1)-deficient mice have been critical in demonstrating the relation between ABCA1 expression, cellular lipid efflux, and HDL metabolism. The phenotype of the ABCA1-deficient mouse parallels the phenotype observed in human Tangier disease, including substantial reductions in both apolipoprotein B and apolipoprotein AI with confounding affects on ...

The subfamily C ATP-binding cassette (ABCC) transporters mediate multidrug resistance and ion conductance regulation. Recent atomic or near-atomic resolution structures of three physiologically significant ABCC transporters (MRP1, SUR1, and CFTR), determined by using single-particle cryo-electron microscopy (cryo-EM), reveal structural details that help explain the wide functional diversity of ...

To investigate iron uptake, a chromosomal locus containing three consecutive open reading frames, designated fhuC, fhuB, and fhuD, was identified in Staphylococcus aureus. Whereas the fhuC gene encodes an ATP-binding protein, fhuB and fhuD code for ferrichrome permeases and thus resemble an ATP-binding cassette transporter. A fhuB knockout mutant showed impaired uptake of iron bound to the side...

OBJECTIVE Phospholipid transfer protein (PLTP), which binds phospholipids and facilitates their transfer between lipoproteins in plasma, plays a key role in lipoprotein remodeling, but its influence on nascent high-density lipoprotein (HDL) formation is not known. The effect of PLTP overexpression on apolipoprotein A-I (apoA-I) lipidation by primary mouse hepatocytes was investigated. APPROAC...
