Wild type PC12 pheochromocytoma cells express a Na(+)-dependent norepinephrine transporter that operates in the uptake of catecholamines, including dopamine. This transporter is not expressed in two spontaneously occurring flat cell variants of PC12 or in two other flat cell variants whose phenotype was induced by expression of the Wnt-1 oncogene. However, each of the flat cell variants, includ...

Glucose is an osmotic agent in the peritoneal dialysis fluid (PDF) to absorb water, sodium and other toxins. absorption from PDF blood impairs (PD) efficiency cause glycemic burden. This extra load leads poor control diabetic patients with PD program. Studies have shown sodium-glucose co-transporter (SGLT)-2 expression mesothelial cells. Blockade of SGLT reduced glucose increment increased rete...

Glutamate transport by the excitatory amino acid transporters (EAATs) is coupled to the co-transport of 3 Na(+), 1 H(+), and the counter-transport of 1 K(+) ion. In addition to coupled ion fluxes, glutamate and Na(+) binding to the transporter activates a thermodynamically uncoupled anion conductance through the transporter. In this study, we have distinguished between these two conductance sta...

To test the hypothesis that AA transporter transcripts are present in the large intestine and similarly expressed along the intestinal tract, mRNA abundance of candidate AA transporter genes solute carrier (SLC) family 7, member 9 (SLC7A9), SLC7A1, SLC7A8, and SLC43A1 encoding for b(0,+)-type AA transporter (b(0,+)AT), cationic AA transporter-1 (CAT-1), L-type AA transporter-2 (LAT-2), and L-ty...

The transport of glutamate across the plasma membrane is coupled to the movement of cations (Na+, K+, and H+) that are necessary for glutamate uptake and transporter cycling as well as anions that are uncoupled from the flux of glutamate. Although the relationship between these coupled (stoichiometric) and uncoupled (anion) transporter currents is poorly understood, transporter-associated anion...

We describe an implemented model of glucose absorption in the enterocyte, as previously published by Afshar et al. (2019), The used mechanistic descriptions all responsible transporters and was built CellML framework. It validated against experimental data a modular structure which allows each individual transporter to be edited independently from other transport protein models. composite then ...

Metabolic engineering of microbial hosts for the production heterologous metabolites and biochemicals is an enabling technology to generate meaningful quantities desired products that may be otherwise difficult produce by traditional means. Heterologous metabolite can restricted accumulation toxic within cell. Efflux transport proteins (transporters) provide a potential solution facilitate expo...
