Phosphatidylinositol (4,5)-bisphosphate turnover by INP51 regulates the cell wall integrity pathway in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2004
Signal transduction pathways are important for the cell to transduce external or internal stimuli where second messengers play an important role as mediators of the stimuli. One important group of second messengers are the phosphoinositide family present

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Distribution of Phosphate Solubilizing Bacteria and Soil Phosphatase Activity in Different Land Uses

open access: yesمجله آب و خاک, 2016
Introduction: Phosphorous is one of the essential macronutrients for plant growth and development but its mobility in soil is very low. The utilization of the soil biological potential, in particular phosphate solubilizing bacteria, is an efficient way ...

Membrane topology of the ArsB protein, the membrane subunit of an anion-translocating ATPase [PDF]

open access: yes, 1992
The ars operon of the conjugative R-factor R773 encodes an oxyanion pump that catalyzes extrusion of arsenicals from cells of Escherichia coli. The oxyanion translocation ATPase is composed of two polypeptides, the catalytic ArsA protein and the ...

Lactoferrin treatment activates acetylcholinesterase, decreasing acetylcholine levels in non‐small cell lung cancer (NSCLC) cell culture supernatants, inhibiting cell survival

open access: yesFEBS Open Bio, EarlyView.
Representation of the suggested mode of action of lactoferrin (Lf) in nonsmall cell lung cancer (NSCLC) A549 cells. Lf induces activation of caspase‐3 by activating p53 and AChE leading to decreased ACh concentrations. In turn, ACh signaling leads to activation of VEGF and AKT and blocking of caspase‐3.

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.
