Article Title: Enhanced uptake and transport of (+)-catechin and (-)-epigallocatechin gallate in niosomal formulation by human intestinal Caco-2 cells
Figure Lengend Snippet: Transport of catechin, EGCG, and their niosomes by human intestinal Caco-2 cells. Notes: Schematic diagram of transcellular transport and different transporters in Caco-2 cells ( A ); effect of concentration on the flux of catechin, EGCG, and their niosomes (0, 10, 20, 50, and 100 μg/mL) through Caco-2 monolayer from apical to basolateral chamber ( B ); effect of temperature (4°C and 37°C), ATP inhibitor (sodium azide), P-gp inhibitor (verapamil), MRP2 inhibitor (MK-571) and absorption enhancer (EDTA) on transport of 100 μg/mL different drugs after 6 hours ( C ). Data are presented as mean ± SD (n=3). Abbreviations: EDTA, ethylenediaminetetraacetic acid; EGCG, (−)-epigallocatechin gallate; MRP2, multidrug resistance-associated protein 2; P-gp, permeability glycoprotein; SD, standard deviation.
