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

Ca 2+ oscillation frequency decoding in cardiac cell hypertrophy: Role of calcineurin/NFAT as Ca 2+ signal integrators [PDF]
Proceedings of the National Academy of Sciences, 2008 The role of Ca2+ signaling in triggering hypertrophy was investigated in neonatal rat cardiomyocytes in vitro. We show that an increase in cell size and sarcomere reorganization were elicited by receptor agonists such as Angiotensin II, aldosterone, and ...

Study of the Synchronization and Transmission of Intracellular Signaling Oscillations in Cells Using Bispectral Analysis. [PDF]
Biology (Basel)The oscillation synchronization analysis in biological systems will expand our knowledge about the response of living systems to changes in environmental conditions. This knowledge can be used in medicine (diagnosis, therapy, monitoring) and agriculture (increasing productivity, resistance to adverse effects).

Cellular Architecture Regulates Collective Calcium Signaling and Cell Contractility. [PDF]
PLoS 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 ...

Heat Oscillations Driven by the Embryonic Cell Cycle Reveal the Energetic Costs of Signaling [PDF]
Developmental Cell, 2020 All living systems function out of equilibrium and exchange energy in the form of heat with their environment. Thus, heat flow can inform on the energetic costs of cellular processes, which are largely unknown. Here, we have repurposed an isothermal calorimeter to measure heat flow between developing zebrafish embryos and the surrounding medium.

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

Oscillations in a cAMP signalling model for cell aggregation – a geometric analysis [PDF]
Journal of Mathematical Analysis and Applications, 2019 Abstract We study a singularly perturbed model for a cyclic adenosine monophosphate (cAMP) signalling system that controls aggregation of the amoeboid microorganism Dictyostelium discoideum. The model, which is based on a classical model due to Martiel and Goldbeter [16] , takes the form of a planar system of ordinary differential equations with two

Visualization of Notch Signaling Oscillation in Cells and Tissues [PDF]
, 2014 The Notch signaling effectors Hes1 and Hes7 exhibit oscillatory expression with a period of about 2-3 h during embryogenesis. Hes1 oscillation is important for proliferation and differentiation of neural stem cells, whereas Hes7 oscillation regulates periodic formation of somites.
