Plant High-Affinity Potassium (HKT) transporters involved in salinity tolerance: structural insights to probe differences in ion selectivity [PDF]

, 2013
High-affinity Potassium Transporters (HKTs) belong to an important class of integral membrane proteins (IMPs) that facilitate cation transport across the plasma membranes of plant cells.

Construction of a Fluorescence‐Based Logic Gate Seeing the Effect of Perchlorate Ions on Hemicyanine Dye–β‐Cyclodextrin Complexes to Certify Safe Drinking Water

ChemistryOpen, EarlyView.
A method to detect perchlorate ions and certify safe drinking water by constructing a fluorescence‐based logic gate considering the binding of a hemicyanine dye with β‐CD is presented. Perchlorate ions (ClO4−) are prevalent contaminants in the surface, and drinking water that disrupt thyroid function by competitively inhibiting the sodium‐iodide ...

Use of progress curves to estimate the co-substrate-to-substrate flow ratio of a symport mechanism. Application to the isoleucine-Na+ symport of mouse ascites-tumour cells and to the lactose-proton symport [PDF]

Biochemical Journal, 1988
The model envisages two components in the process, whereby Ht equivalents of co-substrate and St equivalents of substrate accumulate in the cellular compartment in time t. The first is the flow through the symport, n equivalents of co-substrate entering or leaving with each substrate equivalent.

Hypoxia Inhibitor Improves Iodine Uptake Disorder in Thyroid Cancer Through the hsa_circ_0023990/miR‐448/DNMT1/NIS Axis

Cancer Science, EarlyView.
Our study reveals that hypoxia inhibitors ameliorate iodine uptake dysfunction in thyroid cancer by acting on the hsa_circ_0023990/miR‐448/DNMT1/NIS signaling pathway. ABSTRACT This research seeks to investigate how hypoxia inhibitors enhance iodine uptake in thyroid cancer cells. Clinical samples were gathered and assessed for hsa_circ_0023990, DNMT1,

Conformational Space and Dynamics of Sodium-Coupled Symporters [PDF]

Biophysical Journal, 2011
Secondary transporters utilize the free energy stored in the sodium gradient to move a solute against a concentration gradient. The transport process involves a sequence of conformational changes that exposes the substrate and ion binding sites alternatively to the extracellular and the intracellular compartment.

MITOCHONDRIAL REACTIVE OXYGEN SPECIES (ROS) AS SIGNALLING MOLECULES OF INTRACELLULAR PATHWAYS TRIGGERED BY THE CARDIAC RENIN-ANGIOTENSIN II-ALDOSTERONE SYSTEM (RAAS).

Frontiers in Physiology, 2013
Mitochondria represent major sources of basal reactive oxygen species (ROS) production of the cardiomyocyte. The role of ROS as signalling molecules that mediate different intracellular pathways has gained increasing interest among physiologists in the ...

N‐acetylglucosamine sensing in the filamentous soil fungus Trichoderma reesei

The FEBS Journal, EarlyView.
N‐acetylglucosamine (GlcNAc) is involved in diverse signaling pathways in dimorphic yeasts and bacteria, including virulence and cell death. Here, we investigated GlcNAc sensing in Trichoderma reesei. GlcNAc signaling influences around 2100 genes in this filamentous soil fungus.

Sodium-Sulfate Symport by Aplysia californica Gut [PDF]

Zoological Science, 2000
Sulfate transport across plasma membranes has been described in a wide variety of organisms and cell types including gastrointestinal epithelia. Sulfate transport can be coupled to proton, sodium symport or antiport processes involving chloride or bicarbonate. It had previously been observed in Aplysia gut that sulfate was actively absorbed.

Eukaryotic transporters for hydroxyderivatives of benzoic acid

Scientific Reports, 2017
Several yeast species catabolize hydroxyderivatives of benzoic acid. However, the nature of carriers responsible for transport of these compounds across the plasma membrane is currently unknown.
