Abstract
|
[Objective] To study cellular uptake and pathway of cubic liquid crystalline nanoparticles (LCNPs) on MDCK-MDR1 cells.[Methods] Make LCNPs with calein (Cal-LCNPs), the standard fluorescent substance. Fluorescence intensity in MDCK-MDR1 cells was measured by flow cytometry at different time points. Different inhibitors (Filipin, Phytoalexins D, 2-Deoxy-D-glucose, chlorpromazine) were incubated with Cal-LCNPs. Flow cytometry was used to determine the intracellular fluorescence intensity then determine the pathways.[Results] Cubic liquid crystal nanoparticles can not only increase the uptake of Cal in MDCK-MDR1 cells in 2h, but also alter the uptake behavior of cells. MDCK-MDR1 uptakes Cal was consistent with the zero-order equation, and Cal-LCNPs' was in accordance with the first-order equation. The intracellular fluorescence of cells incubated with chlorpromazine and 2-D-deoxyglucose was low conpared with control (P<0.05).[Conclusion] Cubic liquid crystal nanoparticles can increase the uptake of calcein by MDCK-MDR1, and the pathway is energy-dependent clathrin mediated endocytosis initiative. |
