Here, we compared the effects of nucleofection and lipid-based approaches to introduce siRNA duplexes on the subsequent development of membrane polarity in kidney cells. Nucleofection of Madin-Darby canine kidney (MDCK) cells, even with control siRNA duplexes, disrupted the initial surface polarity as well as the steady-state distribution of membrane(More)
The sialomucin endolyn is implicated in adhesion, migration, and differentiation of various cell types. Along rat kidney tubules, endolyn is variously localized to the apical surface and endosomal/lysosomal compartments. Apical delivery of newly synthesized rat endolyn predominates over direct lysosomal delivery in polarized Madin-Darby canine kidney cells.(More)
Kidney function requires the appropriate distribution of membrane proteins between the apical and basolateral surfaces along the kidney tubule. Further, the absolute amount of a protein at the cell surface versus intracellular compartments must be attuned to specific physiological needs. Endolyn (CD164) is a transmembrane protein that is expressed at the(More)
