Data-driven modelling of receptor tyrosine kinase signalling networks quantifies receptor-specific potencies of PI3K-and Ras-dependent ERK activation
BIOCHEMICAL JOURNAL, 441(1), 77–85.
author keywords: computational biology; cross-talk; growth factor; kinetic analysis; mitogen-activated protein kinase (MAPK); receptor tyrosine kinase
MeSH headings : Animals; Becaplermin; Computer Simulation; Extracellular Signal-Regulated MAP Kinases / genetics; Extracellular Signal-Regulated MAP Kinases / metabolism; Fibroblast Growth Factor 2 / genetics; Fibroblast Growth Factor 2 / metabolism; Fibroblasts / metabolism; Gene Expression Regulation, Enzymologic; Humans; Kinetics; Mice; Models, Biological; NIH 3T3 Cells; Phosphatidylinositol 3-Kinases / genetics; Phosphatidylinositol 3-Kinases / metabolism; Proto-Oncogene Proteins c-sis / genetics; Proto-Oncogene Proteins c-sis / metabolism; Receptor Protein-Tyrosine Kinases / genetics; Receptor Protein-Tyrosine Kinases / metabolism; Receptors, Fibroblast Growth Factor / genetics; Receptors, Fibroblast Growth Factor / metabolism; Signal Transduction
TL;DR:
It is shown that, whereas the FGF stimulation of PI3K signalling is relatively weak, this deficiency is compensated for by a more potent Ras-dependent activation of ERK, and the ERK pathway is activated to a greater extent in cells co-stimulated with FGF and PDGF, relative to the saturated levels achieved with either ligand alone.

Systemic Perturbation of the ERK Signaling Pathway by the Proteasome Inhibitor, MG132
PLOS ONE, 7(11).
Ed(s): L. Buday
MeSH headings : Animals; Computer Simulation; Dual-Specificity Phosphatases / metabolism; Embryo, Mammalian / cytology; Enzyme Activation / drug effects; Fibroblast Growth Factors / pharmacology; Fibroblasts / cytology; Fibroblasts / drug effects; Fibroblasts / enzymology; Humans; Leupeptins / pharmacology; MAP Kinase Signaling System / drug effects; Mesoderm / cytology; Mice; Mitogen-Activated Protein Kinase Kinases / metabolism; NIH 3T3 Cells; Phosphorylation / drug effects; Platelet-Derived Growth Factor / pharmacology; Proteasome Inhibitors / pharmacology; Up-Regulation / drug effects
TL;DR:
It is shown that the effects of MG132 treatment on ERK signaling are more widespread, leading to a reduction in activation of the upstream kinase MEK, suggesting that MG132 systemically perturbs the intracellular phosphoproteome, impactingERK signaling by reducing phosphorylation status at multiple levels of the kinase cascade.

Allosteric Modulation of Ras-GTP Is Linked to Signal Transduction through RAF Kinase
JOURNAL OF BIOLOGICAL CHEMISTRY, 286(5), 3323–3331.
MeSH headings : Allosteric Regulation; Allosteric Site; Animals; Guanosine Triphosphate / metabolism; Kinetics; Mice; Mutation, Missense; NIH 3T3 Cells; Protein Conformation; Protein Stability; Signal Transduction; raf Kinases / metabolism; ras Proteins / genetics; ras Proteins / metabolism
TL;DR:
The allosteric switch is linked to the control of signaling in the Ras/Raf/MEK/ERK pathway, supporting a GTPase-activating protein-independent model for duration of the Ras-Raf complex.

Stochastic Model of Integrin-Mediated Signaling and Adhesion Dynamics at the Leading Edges of Migrating Cells
PLOS COMPUTATIONAL BIOLOGY, 6(2).
Ed(s): A. Asthagiri

TL;DR:
This work has formulated a quantitative model of leading edge dynamics combining mechanistic and phenomenological elements and studied its features through classical bifurcation analysis and stochastic simulation, showing that the qualitative behavior of the model is most sensitive to parameters characterizing the influence of stable adhesion and myosin.

Systematic Quantification of Negative Feedback Mechanisms in the Extracellular Signal-regulated Kinase (ERK) Signaling Network
JOURNAL OF BIOLOGICAL CHEMISTRY, 285(47), 36736–36744.
MeSH headings : Animals; Extracellular Signal-Regulated MAP Kinases / metabolism; Feedback, Physiological; Humans; Immunoblotting; Kinetics; Mice; Mitogen-Activated Protein Kinases / metabolism; NIH 3T3 Cells; Phosphorylation; Signal Transduction; ras Proteins / metabolism
TL;DR:
This work takes a systematic approach to parse the magnitudes of multiple regulatory mechanisms that attenuate ERK activation through canonical (Ras- dependent) and non-canonical (PI3K-dependent) pathways and demonstrates that kinetic models of signaling networks, trained on a sufficient diversity of quantitative data, can be reasonably comprehensive, accurate, and predictive in the dynamical sense.
