Altered MICOS Morphology and Mitochondrial Ion Homeostasis Contribute to Poly(GR) Toxicity Associated with C9-ALS/FTD

open access: yesCell Reports, 2020
Summary: Amyotrophic lateral sclerosis (ALS) manifests pathological changes in motor neurons and various other cell types. Compared to motor neurons, the contribution of the other cell types to the ALS phenotypes is understudied. G4C2 repeat expansion in

Risk homeostasis theory - A study of intrinsic compensation [PDF]

open access: yes, 1996
Risk homeostasis theory (RHT) suggests that changes made to the intrinsic risk of environments are negated in one of three ways: behavioural adjustments within the environment, mode migration, and avoidance of the physical risk.

Homeostasis and synaptic scaling : a theoretical perspective [PDF]

open access: yes, 2013
textAbstract The synaptic input received by neurons in cortical circuits is in constant flux. From both environmental sensory changes and learning mechanisms that modify synaptic strengths, the excitatory and inhibitory signals received by a post ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

The modulation of ion channels in cancer chemo-resistance

open access: yesFrontiers in Oncology, 2022
Ion channels modulate the flow of ions into and out of a cell or intracellular organelle, leading to generation of electrical or chemical signals and regulating ion homeostasis.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

open access: yesFEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Environmental concentrations of N-nitrosodiethylamine (NDEA) disturb the Ca2 + and K+ homeostasis in the gills and epidermis of mosquitofish (Gambusia affinis)

open access: yesEcotoxicology and Environmental Safety
N-nitrosodiethylamine (NDEA), a nitrogenous disinfection by-product, is notorious for its ubiquitous presence in the environment and its carcinogenic properties. However, its impact on ion homeostasis in aquatic organisms remains underexplored.

Transcriptional regulation of salinity stress: role and spatio-temporal expressions of ion-transporter gene promoters

open access: yesBiologia Plantarum, 2018
Ion transporters play an important role in ion homeostasis and control ion flow from its intrusion to exclusion in the entire plant system. Abiotic stress tolerance in plants depends immensely on the activity of these transporters.

Transcription elongation factor AtSPT4-2 positively modulates salt tolerance in Arabidopsis thaliana

open access: yesBMC Plant Biology, 2023
Background Salt stress significantly influences plant growth and reduces crop yield. It is highly anticipated to develop salt-tolerant crops with salt tolerance genes and transgenic technology.

Changes of intracellular sodium and potassium ion concentrations in frog spinal motoneurons induced by repetitive synaptic stimulation [PDF]

open access: yes, 1982
A post-tetanic membrane hyperpolarization following repetitive neuronal activity is a commonly observed phenomenon in the isolated frog spinal cord as well as in neurons of other nervous tissues.
