Estímulo no crescimento e na hidrólise de ATP em raízes de alface tratadas com humatos de vermicomposto: i - efeito da concentração. [PDF]

, 2006
O vermicomposto contém uma concentração elevada de substâncias húmicas e já é bem conhecido o efeito do seu uso sobre as propriedades do solo. No entanto,a ação direta das substâncias húmicas sobre o metabolismo das plantas é menos conhecida.

Cryo-EM structure of a helicase loading intermediate containing ORC-Cdc6-Cdt1-MCM2-7 bound to DNA [PDF]

, 2013
In eukaryotes, the Cdt1-bound replicative helicase core MCM2-7 is loaded onto DNA by the ORC-Cdc6 ATPase to form a prereplicative complex (pre-RC) with an MCM2-7 double hexamer encircling DNA.

Attempt to solubilize Na+/K+-exchanging ATPase with amphiphilic peptide PD1.

Acta Chemica Scandinavica, 1997
The effect of the 24-amino-acid-long peptide, PD(1), on rat cerebral cortical Na+/K+ -exchanging ATPase (EC 3.6.1.37) has been studied. Incubation of the enzyme preparation (25 degrees C for 10-25 min) with the peptide (10(-7) - 10(-4) M) did not ...

The gastric H,K-ATPase in stria vascularis contributes to pH regulation of cochlear endolymph but not to K secretion

BMC Physiology, 2016
BackgroundDisturbance of acid–base balance in the inner ear is known to be associated with hearing loss in a number of conditions including genetic mutations and pharmacologic interventions.

Characterization of humic fractions in leachates from soil under organic and conventional management and their interactions with the root zone [PDF]

, 1978
Humic fractions were shown to be closely involved in gene expression and promotion of different PM H+-ATPase isoforms, as well as in lateral root development, indicating an enhanced nutrient absorption capacity of the plant root system.

Effect of osmotic shrinkage and hormones on the expression of Na+/H+ exchanger-1,Na+/K+/2Cl– cotransporter and Na+/K+-ATPase in gill pavement cells of freshwater adapted Japanese eel,Anguilla japonica [PDF]

Journal of Experimental Biology, 2007
SUMMARYIt is well-known that gill epithelial cells are important in fish osmoregulation. However, studies on the effect of osmotic stress on the direct cellular responses of the gill epithelial cells are limited. In this paper, we aimed to determine the effects of osmotic hypertonicity, hormones and cellular signaling molecules on the expression of ion

Altered Regulation of type 3 Na⁺/H⁺ exchanger, type 1 Na⁺/HCO₃ ^- cotransporter, and Na⁺,K⁺-ATPase in the Kidney of Rats with Experimental Rhabdomyolysis [PDF]

Electrolyte & Blood Pressure, 2007
Metabolic acidosis was shown to correlate with deterioration of renal function in patients with rhabdomyolysis. The present study was aimed to investigate whether the changes of type 3 Na(+)/H(+) exchanger (NHE3), type 1 Na(+)/HCO3 (-) cotransporter (NBC1), and Na(+),K(+)-ATPase α1 subunit may play a role in the pathogenesis of metabolic acidosis in ...

Evaluation of four different strategies to characterize plasma membrane proteins from banana roots [PDF]

, 2015
Plasma membrane proteins constitute a very important class of proteins. They are involved in the transmission of external signals to the interior of the cell and selective transport of water, nutrients and ions across the plasma membrane.

Cell cycle-dependent and kinase-specific regulation of the apical Na/H exchanger and the Na,K-ATPase in the kidney cell line LLC-PK1 by calcitonin. [PDF]

Proceedings of the National Academy of Sciences, 1994
Calcitonin (CT), which regulates serum calcium through its actions in bone and the kidney tubule, also has a potent natriuretic effect in vivo. Na reabsorption in the proximal kidney tubule is mostly dependent on the activity of the Na,K-ATPase and the apical Na/H exchanger.
