Dissection of MKK6 and p38 Signaling Using Light-Activated Protein Kinases
Rahman, S. M. T., Zhou, W., Deiters, A., & Haugh, J. M. (2023, November 7). CHEMBIOCHEM, Vol. 11.
author keywords: apoptosis; autophagy; cell death; growth factors; mitogen-activated protein kinases; optogenetics; signal transduction
TL;DR:
Although decaging active p38α does not reduce basal ERK activity in cells, it can block growth factor‐stimulated ERK signaling in serum‐starved cells, which clarifies the roles of MKK6 and p38α in dynamic signaling programs, which act in concert to actuate apoptotic death while suppressing cell survival mechanisms.

G-actin diffusion is insufficient to achieve F-actin assembly in fast-treadmilling protrusions
BIOPHYSICAL JOURNAL, 122(18), 3816–3829.
TL;DR:
An experimental system in which cells adopt an approximately constant and symmetrical shape and exhibit fast, steady treadmilling in the thin region protruding from the cell is applied, revealing that diffusion alone cannot account for the transport of G-actin to the leading edge.

Isoform-specific optical activation of kinase function reveals p38-ERK signaling crosstalk
RSC CHEMICAL BIOLOGY, 4(10), 765–773.
TL;DR:
Using the photoactivated p38 isoforms, a method for the selective perturbation of the individual protein isoforms of the mitogen-activated protein kinase (MAPK) p38 is described, which identifies a novel point of crosstalk between two major signaling cascades: the p38/MAPK pathway and the extracellular signal-regulated Kinase (ERK)/ MAPK pathway.

On the inference of ERK signaling dynamics from protein biosensor measurements
MOLECULAR BIOLOGY OF THE CELL, 34(6).
MeSH headings : Biosensing Techniques; Extracellular Signal-Regulated MAP Kinases / metabolism; MAP Kinase Signaling System; Phosphorylation; Signal Transduction
TL;DR:
Monitoring ERK signaling using four commonly used translocation- and Förster resonance energy transfer-based biosensors in a common cell stimulation context found that each biosensor responds with unique kinetics; it is clear that there is not a single dynamic signature characterizing the complexity of ERK phosphorylation, translocation, and kinase activity.

Kinetic Modeling and Analysis of the Akt/Mechanistic Target of Rapamycin Complex 1 (mTORC1) Signaling Axis Reveals Cooperative, Feedforward Regulation

Live-Cell Fluorescence Microscopy with Molecular Biosensors: What Are We Really Measuring?
BIOPHYSICAL JOURNAL, 102(9), 2003–2011.
MeSH headings : Animals; Humans; Microscopy, Fluorescence / methods; Molecular Imaging / methods; Molecular Probe Techniques; Molecular Probes / metabolism; Protein Interaction Mapping / methods
TL;DR:
To address the pitfalls of the biosensor approach in quantitative terms, simple reaction-diffusion models were analyzed and a sobering insight emerges: the observer or saturation effect is always significant; the question is whether or not it can be tolerated or accounted for.

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.

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.

Quantitative model of Ras-phosphoinositide 3-kinase signalling cross-talk based on co-operative molecular assembly
BIOCHEMICAL JOURNAL, 393(1), 235–243.
author keywords: mathematical modelling; phosphoinositide 3-kinase (PI3K); platelet-derived growth factor (PDGF); Ras; receptor tyrosine kinase; signal transduction
MeSH headings : Animals; Mice; Models, Biological; NIH 3T3 Cells; Phosphatidylinositol 3-Kinases / metabolism; Proto-Oncogene Proteins c-akt / metabolism; Receptors, Platelet-Derived Growth Factor / metabolism; Signal Transduction; ras GTPase-Activating Proteins / metabolism
TL;DR:
Experiments with platelet-derived growth factor-stimulated fibroblasts revealed that Ras apparently enhances the affinity of PI3K for receptors, which suggests that a ternary complex does indeed form, with the second step greatly enhanced through membrane localization and possibly allosteric effects.
