Sodium/iodide symporter (NIS) and cytokines

Experimental and Clinical Endocrinology & Diabetes, 2001
It has been shown that TSH upregulates rat NIS gene expression in vitro, and this induction can be modulated by cytokines. Analysis of the distribution of rat NIS mRNA ex vivo demonstrated variable levels of NIS transcription in different tissue samples. - IL-1beta and IL-6 have been found to decrease NIS mRNA expression in TSH-stimulated FRTL-5-cells.

P Systems with Symport/Antiport and Time

2006
We consider symport/antiport P systems using the time as the support for the output of a computation. We describe and study the properties of “timed symport/antiport systems”, showing that this new model of membrane systems based on time has more power/flexibility, and thus allows us to improve previous universality results.

On Nonuniversal Symport/Antiport P Systems

2009
We examine restricted SA P system models and analyze minimal systems with regard to the size of the alphabet and the number of membranes. We study the precise power of SA P systems with either 1, 2, or 3 symbols and less than 5, 4, and 3 membranes, respectively, improving the previous results. The question of whether using only a single symbol with any

Sugar—Cation Symport Systems in Bacteria

1992
Publisher Summary This chapter describes sugar–cation symport systems in bacteria and presents the properties of the bacterial sugar–H + transport proteins, their substrate specificities, effects of certain inhibitors, their genes, and the amino acid sequences of the proteins.

Sodium Iodide Symporter in Thyroid Carcinoma

2012
Thyroid iodide uptake is essential for the clinical application of radioiodine in patients with well-differentiated thyroid carcinoma. Iodide uptake occurs across the plasma membranes of thyroid follicular cells and cancer cells via an active transporter process mediated by sodium iodide symporter (NIS).
