Fixation-induced cell blebbing on spread cells inversely correlates with phosphatidylinositol 4,5-bisphosphate level in the plasma membrane

open access: yesFEBS Open Bio, 2014
While most attention has been focused on physiologically generated blebs, the molecular mechanisms for fixation-induced cell blebbing are less investigated. We show that protein-fixing (e.g. aldehydes and picric acid) but not lipid-stabilizing (e.g. OsO4

Examining the role of insulin in the regulation of cardiovascular health [PDF]

open access: yes, 2013
A substantial body of evidence has reported that insulin has direct actions on the cardiovascular system independent of its systemic effects on plasma glucose or lipids.

PIP2 Influences the Conformational Dynamics of Membrane bound KRAS4b

open access: yesbioRxiv, 2019
KRAS4b is a small GTPase involved in cellular signaling through receptor tyrosine kinases. Activation of KRAS4b is achieved through the interaction with nucleotide exchange factors while inactivation is regulated by through interaction with GTPase ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

open access: yesJournal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Dual Regulation of Kv1.2 Activation by PIP2 [PDF]

open access: yesBiophysical Journal, 2011
Phosphatidylinositol (4,5)-bisphosphate is now recognized as a ubiquitous regulator of ion channels and transporters. We report here that PIP2 regulates activation of Kv1.2, a Shaker family voltage-gated potassium channel. In inside-out macropatches of Xenopus laevis oocytes, loss of PIP2 induced a leftward shift in the voltage-dependence of activation

So far, yet so close: α-Catenin dimers help migrating cells get together [PDF]

open access: yes, 2017
Epithelial cells in tissues use their actin cytoskeletons to stick together, whereas unattached cells make active plasma membrane protrusions to migrate. In this issue, Wood et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201612006) show that the

Contribution of Sympathetic Sensory Coupling to Craniofacial Nociception

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Stress and anxiety are associated with increased pain intensity in temporomandibular disorders (TMDs) patients. It is possible that this association is due to a direct interaction between the sympathetic and sensory nervous systems. This narrative review examines evidence for a potential sympathetic sensory interaction in deep craniofacial ...

SALM1 controls synapse development by promoting F‐actin/PIP2‐dependent Neurexin clustering

open access: yesEMBO Journal, 2019
Synapse development requires spatiotemporally regulated recruitment of synaptic proteins. In this study, we describe a novel presynaptic mechanism of cis‐regulated oligomerization of adhesion molecules that controls synaptogenesis. We identified synaptic

Perturbation of Anion/Cation Transport Leads to Apical Panicle Abortion in Rice by Disrupting Ca2+ Homeostasis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Calcium ion (Ca2+) is an essential plant nutrient required for cell structure establishment, as well as a counter‐cation of an anion and an intracellular messenger. Calcium is absorbed from soil by roots and delivered to shoots through the xylem. The process must be finely balanced to avoid excessive accumulation.

Phosphoinositide Modulation of Heteromeric Kv1 Channels Adjusts Output of Spiral Ganglion Neurons from Hearing Mice [PDF]

open access: yes, 2015
Spiral ganglion neurons (SGNs) relay acoustic code from cochlear hair cells to the brainstem, and their stimulation enables electrical hearing via cochlear implants. Rapid adaptation, a mechanism that preserves temporal precision, and a prominent feature
