Insights into the role of intracellular calcium signaling in the neurobiology of neurodevelopmental disorders

open access: yesFrontiers in Neuroscience, 2023
Calcium (Ca2+) comprises a critical ionic second messenger in the central nervous system that is under the control of a wide array of regulatory mechanisms, including organellar Ca2+ stores, membrane channels and pumps, and intracellular Ca2+-binding ...

Induction of Intracellular Ca2+ and pH Changes in Sf9 Insect Cells by Rhodojaponin-III, A Natural Botanic Insecticide Isolated from Rhododendron molle

open access: yesMolecules, 2011
Many studies on intracellular calcium ([Ca2+]i) and intracellular pH (pHi) have been carried out due to their importance in regulation of different cellular functions. However, most of the previous studies are focused on human or mammalian cells.

Decavanadate displaces inositol 1,4,5-trisphosphate (IP3) from its receptor and inhibits IP3 induced Ca2+ release in permeabilized pancreatic acinar cells [PDF]

open access: yes, 1991
Inositol 1,4,5-trisphosphate (IP3) induced Ca2+ release in digitonin permeabilized rat pancreatic acinar cells is specifically inhibited by decavanadate.

Interaction between age and obesity on cardiomyocyte contractile function: role of leptin and stress signaling. [PDF]

open access: yesPLoS ONE, 2010
This study was designed to evaluate the interaction between aging and obesity on cardiac contractile and intracellular Ca2+ properties.Cardiomyocytes from young (4-mo) and aging (12- and 18-mo) male lean and the leptin deficient ob/ob obese mice were ...

Endothelin and increased contractility in adult rat ventricular myocytes. Role of intracellular alkalosis induced by activation of the protein kinase C-dependent Na(+)-H+ exchanger [PDF]

open access: yes, 1991
Endothelin, a 21-amino acid vasoactive peptide, is among the most potent positively inotropic agents yet described in mammalian heart. Having demonstrated that endothelin's inotropic effect is due, in part, to an apparent sensitization of cardiac ...

Calmodulin: a highly conserved and ubiquitous Ca2+ sensor

open access: yesProceedings of the Japan Academy. Series B, Physical and Biological Sciences
Calcium ions (Ca2+) play critical roles in various biological phenomena. The free Ca2+ concentration in the cytoplasm of a resting cell is at the 10-7 M level, whereas that outside the cell is 10-3 M, creating a 10,000-fold gradient of Ca2 ...

Ryanodine receptors, a family of intracellular calcium ion channels, are expressed throughout early vertebrate development [PDF]

open access: yes, 2011
Background Calcium signals ([Ca2+]i) direct many aspects of embryo development but their regulation is not well characterised. Ryanodine receptors (RyRs) are a family of intracellular Ca2+ release channels that control the flux of Ca2+ from internal ...

Pharmacological Preconditioning Using Diazoxide Regulates Store-Operated Ca2 + Channels in Adult Rat Cardiomyocytes

open access: yesFrontiers in Physiology, 2020
Voltage-dependent Ca2+ channels and store-operated Ca2+ channels (SOCs) are the major routes of Ca2+ entry into mammalian cells. Previously, we reported that pharmacological preconditioning (PPC) leads to a decrease in the amplitude of L-type calcium ...

Orai1 is an Entotic Ca2+ Channel for Non‐Apoptotic Cell Death, Entosis in Cancer Development

open access: yesAdvanced Science, 2023
Entosis is a non‐apoptotic cell death process that forms characteristic cell‐in‐cell structures in cancers, killing invading cells. Intracellular Ca2+ dynamics are essential for cellular processes, including actomyosin contractility, migration, and ...

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.
