Membrane potential and cancer progression [PDF]

Frontiers in Physiology, 2013
Membrane potential (Vm), the voltage across the plasma membrane, arises because of the presence of different ion channels/transporters with specific ion selectivity and permeability.

Mitochondrial membrane potential. [PDF]

Analytical Biochemistry, 2017
The mitochondrial membrane potential (ΔΨm) generated by proton pumps (Complexes I, III and IV) is an essential component in the process of energy storage during oxidative phosphorylation. Together with the proton gradient (ΔpH), ΔΨm forms the transmembrane potential of hydrogen ions which is harnessed to make ATP.

Potentiality of raloxifene loaded melittin functionalized lipidic nanovesicles against pancreatic cancer cells

Drug Delivery, 2022
Pancreatic cancer (PC) frequency and incidence have grown rapidly in recent years. One of the most serious problems with PC is the existence of asymptotic manifestations, which frequently delays early detection, and until the diagnosis is established ...

The membrane potential of Giardia intestinalis [PDF]

FEMS Microbiology Letters, 2000
Giardia intestinalis is a primitive microaerophilic protozoan parasite which colonises the upper intestine of humans. Despite the evolutionary and medical significance of this organism, its physiology is very poorly understood. In this study we have used a novel flow cytometric technique to make quantitative measurements of the electrical potential ...

Effect of sodium humate on membrane potential in internodal cells of Nitellopsis obtusa

Acta Societatis Botanicorum Poloniae, 2014
Membrane potential and resistance changes in Nitellopsis obtusa induced by Na-humate as a function of external pH were investigated. The administration of Na-humate at concentrations of 12.5, 25, 50 and 100 mg dm-3 brought about a hyperpolarization of ...

Investigating membrane breakdown of neuronal cells exposed to nonuniform electric fields by finite-element modeling and experiments [PDF]

, 2002
High electric field strengths may induce high cell membrane potentials. At a certain breakdown level the membrane potential becomes constant due to the transition from an insulating state into a high conductivity and high permeability state.

Transport of F1-ATPase subunit β into mitochondria depends on both a membrane potential and nucleoside triphosphates [PDF]

, 1986
Transport of cytoplasmically synthesized precursor proteins into or across the inner mitochondrial membrane requires a mitochondrial membrane potential.

Requirement of a Membrane Potential for the Posttranslational Transfer of Proteins into Mitochondsria [PDF]

, 1982
Posttranslational transfer of most precursor proteins into mitochondria is dependent on energization of the mitochondria. Experiments were carried out to determine whether the membrane potential or the intramitochondrial ATP is the immediate energy ...
