Receptor-mediated delivery of therapeutic RNA by peptide functionalized curdlan nanoparticles.
Abstract Natural carbohydrate polymer-based nanoparticles have great biocompatibility that is required for the safe delivery of various drugs including nucleic acid therapeutics. Herein, we designed curdlan-based nanoparticles for cancer cell targeted delivery of short interfering RNA (siRNA). iRGD peptide conjugated 6-amino-6-deoxy curdlan specifically delivered siRNA to integrin expressing cancer cells. Incubation of cancer cells with free iRGD peptide competitively blocked cellular uptake of the iRGD functionalized curdlan nanoparticles. Chloroquine but not nystatin inhibited cellular uptake of iRGD functionali...

FXYD3 facilitates Na < sup > + < /sup > and liquid absorption across human airway epithelia by increasing the transport capacity of the Na/K ATPase
Am J Physiol Cell Physiol. 2022 Aug 22. doi: 10.1152/ajpcell.00047.2022. Online ahead of print.ABSTRACTNa/K ATPase activity is essential for ion transport across epithelia. FXYD3, a ᵯE; subunit of the Na/K ATPase, is expressed in the airway, but its function remains undetermined. Single cell RNA sequencing and immunohistochemistry revealed that FXYD3 localizes within the basolateral membrane of all airway epithelial cells. To study FXYD3 function, we reduced FXYD3 expression using siRNA. After permeabilizing the apical membrane with nystatin, epithelia pretreated with FXYD3-targeting siRNA had lower ouabain-sensitive sho...

Differential Requirements of Arrestin-3 and Clathrin for Ligand-dependent and -independent Internalization of Human G Protein-coupled Receptor 40.
Abstract G protein-coupled receptor 40 (GPR40) is believed to be an attractive target to enhance insulin secretion in patients with type 2 diabetes. GPR40 has been found to couple to Gq protein, leading to activation of phospholipase C and subsequent increases in the intracellular Ca(2+) level. However, the underlying mechanisms that regulate the internalization and desensitization of GPR40 remain to be elucidated. In the present study, a construct of GPR40 fused with enhanced green fluorescent protein (EGFP) at its C-terminus was constructed for direct imaging of the localization and internalization of GPR40 by c...

Porcine sapovirus Cowden strain enters LLC-PK cells via clathrin- and cholesterol-dependent endocytosis with the requirement of dynamin II
AbstractCaliciviruses in the genusSapovirus are a significant cause of viral gastroenteritis in humans and animals. However, the mechanism of their entry into cells is not well characterized. Here, we determined the entry mechanism of porcine sapovirus (PSaV) strain Cowden into permissive LLC-PK cells. The inhibition of clathrin-mediated endocytosis using chlorpromazine, siRNAs, and a dominant negative (DN) mutant blocked entry and infection of PSaV Cowden strain, confirming a role for clathrin-mediated internalization. Entry and infection were also inhibited by the cholesterol-sequestering drug methyl- β-cyclodextrin and...
