Model simplification of signal transduction pathway networks via a hybrid inference strategy [PDF]
, 2008 A full-scale mathematical model of cellular networks normally involves a large number of variables and parameters. How to effectively develop manageable and reliable models is crucial for effective computation, analysis and design of such systems.

Noise-induced Input Dependence in a Convective Unstable Dynamical System
, 1998 Unidirectionally coupled dynamical system is studied by focusing on the input (or boundary) dependence. Due to convective instability, noise at an up-flow is spatially amplified to form an oscillation. The response, given by the down-flow dynamics, shows

p38 Mitogen-activated Protein Kinase Regulates Oscillation of Chick Pineal Circadian Clock [PDF]
, 2003 Extracellular signal-regulated kinase (ERK) and p38 are members of the mitogen-activated protein kinase (MAPK) family, and in some cases these kinases serve for closely related cellular functions within a cell. In a wide range of animal clock structures,

Autonomous Ca2+ Oscillations Reflect Oncogenic Signaling in B-ALL Cells
Blood, 2019 Background: Engagement of the B-cell receptor (BCR) results in Ca2+ flux and is linked to B-cell survival based on store-operated Ca2+ entry (SOCE), which is triggered by ORAI1 and stromal interaction molecule-1 (STIM1). While normal B-cells release Ca2+ only in response to external stimuli (e.g. BCR-engagement), we recently observed that transformed B-

Experimental Design for Stochastic Models of Nonlinear Signaling Pathways Using an Interval-Wise Linear Noise Approximation and State Estimation. [PDF]
PLoS ONE, 2016 BACKGROUND:Computational modeling is a key technique for analyzing models in systems biology. There are well established methods for the estimation of the kinetic parameters in models of ordinary differential equations (ODE).

Human iNKT Cells Promote Protective Inflammation by Inducing Oscillating Purinergic Signaling in Monocyte-Derived DCs [PDF]
Cell Reports, 2016 Invariant natural killer T (iNKT) cells are innate T lymphocytes that promote host defense against a variety of microbial pathogens. Whether microbial ligands are required for their protective effects remains unclear. Here, we show that iNKT cells stimulate human-monocyte-derived dendritic cells (DCs) to produce inflammatory mediators in a manner that ...

iScience, 2020 Summary: Ca2+ oscillations that depend on inositol-1,4,5-trisphosphate (IP3) have been ascribed to biphasic Ca2+ regulation of the IP3 receptor (IP3R) or feedback mechanisms controlling IP3 levels in different cell types.

Stimulation of electro-olfactogram responses in the main olfactory epithelia by airflow depends on the type 3 adenylyl cyclase [PDF]
, 2012 Cilia of olfactory sensory neurons are the primary sensory organelles for olfaction. The detection of odorants by the main olfactory epithelium (MOE) depends on coupling of odorant receptors to the type 3 adenylyl cyclase (AC3) in olfactory cilia.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
