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.

Methods and Protocols, 2020 In this protocol, we introduced a method of measuring mitochondrial dysfunction to confirm the epithelial–mesenchymal transition (EMT) in pancreatic cancer cells under a hypoxic environment. There are many expertized and complicated methods to verify EMT.

Joule heating involving ion currents through channel proteins
Biophysics and Physicobiology, 2023 Ion currents associated with channel proteins in the presence of membrane potential are ubiquitous in cellular and organelle membranes. When an ion current occurs through a channel protein, Joule heating should occur. However, this Joule heating seems to

Membrane Potential Assessment by Fluorimetry as a Predictor Tool of Human Sperm Fertilizing Capacity
Frontiers in Cell and Developmental Biology, 2020 Mammalian sperm acquire the ability to fertilize eggs by undergoing a process known as capacitation. Capacitation is triggered as the sperm travels through the female reproductive tract.

Anoxic spreading depolarization in the neonatal rat cortex in vitro
Frontiers in Cellular Neuroscience, 2023 Anoxic spreading depolarization (aSD) is a hallmark of ischemic injury in the cerebral cortex. In adults, aSD is associated with rapid and nearly complete neuronal depolarization and loss of neuronal functions.

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 ...
