Venlafaxine stabilizes axons of the neurons in depression model mice [PDF]

Jichu yixue yu linchuang
Objective To investigate whether the effects of venlafaxine on major depression disorder is associated with ankyrin G. Methods Breed Synapsin-Cre1 and Ankyrin3-floxed mice (Ank3 cKO mice). Ank3 cKO mice and wild type mice were randomly divided into model

Homeostatic regulation of extracellular signal-regulated kinase 1/2 activity and axonal Kv7.3 expression by prolonged blockade of hippocampal neuronal activity

Frontiers in Cellular Neuroscience, 2022
Homeostatic plasticity encompasses the mechanisms by which neurons stabilize their synaptic strength and excitability in response to prolonged and destabilizing changes in their network activity.

Heparan Sulfates Regulate Axonal Excitability and Context Generalization through Ca²⁺/Calmodulin-Dependent Protein Kinase II

Cells, 2023
Our previous studies demonstrated that enzymatic removal of highly sulfated heparan sulfates with heparinase 1 impaired axonal excitability and reduced expression of ankyrin G at the axon initial segments in the CA1 region of the hippocampus ex vivo ...

Key Role of the Membrane Trafficking of Nav1.5 Channel Protein in Antidepressant-Induced Brugada Syndrome

Frontiers in Physiology, 2018
Anti-depressant treatment has been found to be associated with the development of Brugada syndrome (BrS) through poorly defined mechanisms. Herein, this study aimed to explore the molecular basis for amitriptyline-induced BrS.

Autoinhibition of ankyrin-B/G membrane target bindings by intrinsically disordered segments from the tail regions

eLife, 2017
Ankyrins together with their spectrin partners are the master organizers of micron-scale membrane domains in diverse tissues. The 24 ankyrin (ANK) repeats of ankyrins bind to numerous membrane proteins, linking them to spectrin-based cytoskeletons at ...

The largest isoform of Ankyrin-G is required for lattice structure of the axon initial segment

Biochemical and Biophysical Research Communications, 2021
Alzheimer's disease (AD) is the most frequent neurodegenerative disease and a common dementia in elderly individuals. Previous studies found a strong correlation between axon initial segment (AIS) defects and AD, but it remains unclear whether AD itself changes the arrangement of AIS components, and the mechanisms by which adaptor proteins and ion ...

SiRNA-mediated ankyrin-G silence modulates the expression of voltage-gated Na channels in murine hippocampal HT22 cells

Acta Epileptologica, 2019
Background Voltage-gated sodium channels are the targets of many commonly used antiepileptic drugs. NaV1.6, encoded by Scn8a, increased in chronic mesial temporal epilepsy animal models and co-localized with Ankyrin-G, encoded by Ank3.

Ankyrin-G Is a Molecular Partner of E-cadherin in Epithelial Cells and Early Embryos [PDF]

Journal of Biological Chemistry, 2007
E-cadherin is a ubiquitous component of lateral membranes in epithelial tissues and is required to form the first lateral membrane domains in development. Here, we identify ankyrin-G as a molecular partner of E-cadherin and demonstrate that ankyrin-G and beta-2-spectrin are required for accumulation of E-cadherin at the lateral membrane in both ...

Multiple Domains in the Kv7.3 C-Terminus Can Regulate Localization to the Axon Initial Segment

Frontiers in Cellular Neuroscience, 2020
The voltage-gated Kv7.2/Kv7.3 potassium channel is a critical regulator of neuronal excitability. It is strategically positioned at the axon initial segment (AIS) of neurons, where it effectively inhibits repetitive action potential firing.
