Prostate cancer cells alter the nature of their calcium influx to promote growth and acquire apoptotic resistance [PDF]

open access: yes, 2014
In this issue of Cancer Cell, Dubois and colleagues report a remodeling of calcium influx in prostate cancer cells. Prostate cancer cells can undergo an oncogenic switch from a calcium influx pathway capable of inducing apoptosis involving ORAI1 channels

Cytosolic‐enhanced dark Epac‐based FRET sensors allow for intracellular cAMP detection in live cells via FLIM

open access: yesFEBS Letters, EarlyView.
We describe a novel set of Epac‐based FRET‐FLIM biosensors with improved fully cytosolic distribution, achieved without compromising the state‐of‐the‐art performance of our original designs, for detecting cAMP dynamics in real time in live cells with high precision and reliability.

Suramin-Induced Neurotoxicity: Preclinical Models and Neuroprotective Strategies

open access: yesMolecules, 2018
Suramin is a trypan blue analogon originally developed to treat protozoan infections, which was found to have diverse antitumor effects. One of the most severe side effects in clinical trials was the development of a peripheral sensory-motor ...

Multiscale studies of delayed afterdepolarizations II: Calcium-overload-induced ventricular arrhythmias [PDF]

open access: yesarXiv, 2023
Disturbances in calcium homeostasis in a cardiac myocyte can lead to calcium-overload conditions and abnormal calcium releases, which occur primarily in the following two phases of the action potential (AP): (a) triggered or late calcium release (LCR) during the plateau phase; (b) spontaneous calcium release (SCR) during the diastolic interval (DI ...

Small-molecule CaVα1⋅CaVβ antagonist suppresses neuronal voltage-gated calcium-channel trafficking [PDF]

open access: yes, 2018
Extracellular calcium flow through neuronal voltage-gated CaV2.2 calcium channels converts action potential-encoded information to the release of pronociceptive neurotransmitters in the dorsal horn of the spinal cord, culminating in excitation of the ...

Calcium Channel Engineering [PDF]

open access: yesBiophysical Journal, 2015
High-voltage-activated calcium (CaV) channels convert electrical signals into Ca2+ ion influx to trigger biological responses in excitable cells. CaV channel dysfunction underlies many cardiovascular and neurological diseases, from cardiac arrhythmias to autism. Modulation of CaV channels by intracellular signaling proteins, Ca2+ ions and various small

The [2Fe‐2S] cluster of mitochondrial outer membrane protein mitoNEET has an O2‐regulated nitric oxide access tunnel

open access: yesFEBS Letters, EarlyView.
The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.

A small footprint couch‐top support device for image‐guided radiotherapy of heavy patients

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Patients with body weights close to or above 400 lbs present unique challenges in radiation therapy since the weight limit of most treatment couches decreases as the couch‐top extends toward the treatment gantry. The purpose of this work was to develop a small footprint couch‐top support platform to safely perform image‐guided ...

A Sea Anemone Lebrunia neglecta Venom Fraction Decreases Boar Sperm Cells Capacitation: Possible Involvement of HVA Calcium Channels

open access: yesToxins, 2022
Sea anemones produce venoms characterized by a complex mixture of low molecular weight compounds, proteins and peptides acting on voltage-gated ion channels. Mammal sperm cells, like neurons, are characterized by their ion channels. Calcium channels seem

Root growth and signalling: the role of calcium channels [PDF]

open access: yes, 2017
Roots acquire calcium not only as a macronutrient but also to serve as a second messenger in signalling and a component of exocytosis for growth. Plasma membrane channels are sufficient to deliver calcium from the apoplast to the cytosol to enable its ...
