Cellular Architecture Regulates Collective Calcium Signaling and Cell Contractility.

open access: yesPLoS Computational Biology, 2016
A key feature of multicellular systems is the ability of cells to function collectively in response to external stimuli. However, the mechanisms of intercellular cell signaling and their functional implications in diverse vascular structures are poorly ...

A model of cell biological signaling predicts a phase transition of signaling and provides mathematical formulae. [PDF]

open access: yesPLoS ONE, 2014
A biological signal is transmitted by interactions between signaling molecules in the cell. To date, there have been extensive studies regarding signaling pathways using numerical simulation of kinetic equations that are based on equations of continuity ...

The Roles of Fission Yeast Ase1 in Mitotic Cell Division, Meiotic Nuclear Oscillation, and Cytokinesis Checkpoint Signaling [PDF]

open access: yesMolecular Biology of the Cell, 2005
The Ase1/Prc1 proteins constitute a conserved microtubule-associated protein family that is implicated in central spindle formation and cytokinesis. Here we characterize a role for fission yeast Ase1. Ase1 localizes to microtubule overlapping zones and displays dynamic alterations of localization during the cell cycle.

Clofazimine inhibits human Kv1.3 potassium channel by perturbing calcium oscillation in T lymphocytes. [PDF]

open access: yesPLoS ONE, 2008
The Kv1.3 potassium channel plays an essential role in effector memory T cells and has been implicated in several important autoimmune diseases including multiple sclerosis, psoriasis and type 1 diabetes.

A transcriptomic taxonomy of Drosophila circadian neurons around the clock

open access: yeseLife, 2021
Many different functions are regulated by circadian rhythms, including those orchestrated by discrete clock neurons within animal brains. To comprehensively characterize and assign cell identity to the 75 pairs of Drosophila circadian neurons, we ...

Dynamic expression of Notch signaling genes in neural stem/progenitor cells

open access: yesFrontiers in Neuroscience, 2011
In neural stem/progenitor cells, expression of the Notch effector Hes1, a transcriptional repressor, oscillates with a period of 2-3 hours by negative feedback, and Hes1 oscillations induce the oscillatory expression of the proneural gene Neurogenin2 ...

Cross-talk between signaling pathways can generate robust oscillations in calcium and cAMP. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:To control and manipulate cellular signaling, we need to understand cellular strategies for information transfer, integration, and decision-making.

Dynamic intracellular mechanical cues facilitate collective signaling responses

open access: yesiScience, 2021
Summary: Collective behavior emerges in diverse life machineries, e.g., the immune responses to dynamic stimulations. The essential questions that arise here are that whether and how cells in vivo collectively respond to stimulation frequencies higher ...

Loss of thyroid gland circadian PER2 rhythmicity in aged mice and its potential association with thyroid cancer development

open access: yesCell Death and Disease, 2022
Molecular clocks operate in peripheral tissues, including endocrine glands, and play important regulatory roles in this context. However, potential age-related changes in the expression rhythmicity of clock genes and the effects of these changes on the ...
