The conduction pathway of potassium channels is water free under physiological conditions. [PDF]

open access: yes, 2019
Ion conduction through potassium channels is a fundamental process of life. On the basis of crystallographic data, it was originally proposed that potassium ions and water molecules are transported through the selectivity filter in an alternating ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

open access: yesMolecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Effects of Potassium Source and Secondary Nutrients on Potato Yield and Quality in Southcentral Alaska. [PDF]

open access: yes, 1990
Calcium (Ca), magnesium (Mg), and sulfur (S) are required for the growth and development of all higher plants. They are commonly referred to as secondary nutrients because they are less often limiting to plant growth than the primary nutrients nitrogen ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Genetic signature in mineral nutrition in oil palm (Elaeis guineensis Jacq.): A new panorama for high yielding materials at low fertiliser cost [PDF]

open access: yes, 2009
Significant differences in mineral nutrition have been demonstrated between progenies and main categories at PT Socfindo (Jacquemard et al, 2002). New set of investigation has been conducted based on larger genetic background.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Occurrence of potassium location in oil palm tissues with reserve sugars: consequences for oil palm K status determination [PDF]

open access: yes, 2014
In some fertilizer trials for oil palm, it is observed that potassium leaf content was not in concordance with potassium application. In some cases no "leaf" response is observed (leaflet potassium content from leaf rank 17 according to specific LD IRHO ...

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

open access: yesFEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

Genomic organization and chromosomal localization of the murine 2 P domain potassium channel gene Kcnk8: conservation of gene structure in 2 P domain potassium channels. [PDF]

open access: yes, 2000
A 2 P domain potassium channel expressed in eye, lung, and stomach, Kcnk8, has recently been identified. To initiate further biochemical and genetic studies of this channel, we assembled the murine Kcnk8 cDNA sequence, characterized the genomic structure
