Tissue factor (TF) is the most important trigger of blood coagulation in vascular pathology. Rabbit TF, with or without (delta C) its COOH-terminal intracellular tail, has been conjugated to green fluorescent protein (GFP) to study subcellular localization and other functions of TF. TF-GFP and TF delta C-GFP are associated with Na2CO3-resistant buoyant fractions in HEK-293 cells (lipid rafts); ...

Thiamin (vitamin B(1)) is essential for normal cellular functions. The kidneys play a critical role in regulating body thiamin homeostasis, by salvaging the vitamin via reabsorption from the glomerular filtrate, but little is known about the mechanism(s) and regulation of thiamin transport in the human renal epithelia at cellular and molecular levels. Using the human-derived renal epithelial HE...

The multidrug resistance protein MRP1 functions as an ATP-dependent conjugate export pump and confers multidrug resistance. We cloned MRP2 (symbol ABCC2), a MRP family member localized to the apical membrane of polarized cells. Stable expression of MRP2 in transfected human embryonic kidney (HEK-293) and Madin-Darby canine kidney (MDCK) cells was enhanced by inhibitors of histone deacetylase. I...
