Cloning of the Human Sodium Iodide Symporter

Biochemical and Biophysical Research Communications, 1996
The iodide concentrating activity of the thyroid gland is essential to the production of thyroid hormone and also provides a mechanism for the treatment of thyroid cancer by radioiodine ablation. We report here the nucleotide and amino acid sequence of the human sodium iodide symporter (hNIS), which mediates the iodide uptake activity in the thyroid ...

Cloning of the Mouse Sodium Iodide Symporter

Thyroid, 2001
The iodide-concentrating ability of the thyroid gland is essential to the production of thyroid hormone. We report the nucleotide and amino acid sequence of the mouse sodium iodide symporter (mNIS), which mediates this activity within the thyroid gland.

The chlorella hexose/H+-symporters

2000
The physiology, molecular biology, and biochemistry of the inducible hexose uptake protein of Chlorella kessleri is reviewed. The protein encoded by the HUP1 gene is the most intensively studied membrane transporter of plants. Responsible for substrate accumulation up to 1500-fold, it translocates one proton together with one hexose, and the cell ...

Thyroid hormone stimulates the Na(+)-PO4 symporter but not the Na(+)-SO4 symporter in renal brush border

American Journal of Physiology-Renal Physiology, 1993
In our previous studies we established that thyroid hormones [L-thyroxine (T4) or 3,5,3'-triiodothyronine (T3)] elicit an increase in Na(+)-Pi symport in rat and mouse renal brush-border membrane (BBM) vesicles (BBMV), but the Na(+)-coupled symports of other solutes were not influenced. However, a recent report [H. S. Tenenhouse, J. Lee, and N. Harvey.

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.

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.

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

On Bounded Symport/Antiport P Systems

2006
We introduce a restricted model of a one-membrane symport/antiport system, called bounded S/A system. We show the following: 1. A language $L \subseteq a_1^* ... a_k^*$ is accepted by a bounded S/A system if and only if it is accepted by a log n space-bounded Turing machine. This holds for both deterministic and nondeterministic versions. 2.
