Fibroblast Migration Is Regulated by Myristoylated Alanine-Rich C-Kinase Substrate (MARCKS) Protein

PLOS ONE, 8(6).

By: L. Ott n, E. Sung  n, A. Melvin n, M. Sheats  n, J. Haugh n , K. Adler n, S. Jones n 

Ed(s): P. Aspenstrom

MeSH headings : 3T3 Cells; Animals; Becaplermin; Chemotaxis / drug effects; Chemotaxis / physiology; Collagen / metabolism; Fibroblasts / cytology; Fibronectins / metabolism; Intracellular Signaling Peptides and Proteins / metabolism; Intracellular Signaling Peptides and Proteins / physiology; Membrane Proteins / metabolism; Membrane Proteins / physiology; Mice; Myristoylated Alanine-Rich C Kinase Substrate; Phosphorylation; Proto-Oncogene Proteins c-akt / metabolism; Proto-Oncogene Proteins c-sis / pharmacology
TL;DR: Genetic structure-function analysis revealed that MANS peptide-mediated attenuation of NIH-3T3 cell migration does not require the presence of the myristic acid moiety on the amino-terminus, and suggests that MARCKS-mediated regulation of fibroblast migration involves the MARC KS amino- terminus.

2012 journal article

Migrating fibroblasts reorient directionality by a metastable, PI3K-dependent mechanism

JOURNAL OF CELL BIOLOGY, 197(1), 105–114.

By: E. Welf n, S. Ahmed n, H. Johnson n, A. Melvin n & J. Haugh n 

MeSH headings : Animals; Cell Movement; Cells, Cultured; Fibroblasts / cytology; Fibroblasts / enzymology; Fibroblasts / metabolism; Mice; NIH 3T3 Cells; Phosphatidylinositol 3-Kinases / metabolism; Phosphoinositide-3 Kinase Inhibitors; Signal Transduction / drug effects
TL;DR: Migrating fibroblasts reorient directionality by PI3K-dependent branching and pivoting of protrusions, a mechanism that allows fibro Blasts to align with an external chemotactic gradient. (via Semantic Scholar)

2011 journal article

In Chemotaxing Fibroblasts, Both High-Fidelity and Weakly Biased Cell Movements Track the Localization of PI3K Signaling

BIOPHYSICAL JOURNAL, 100(8), 1893–1901.

By: A. Melvin n, E. Welf n, Y. Wang *, D. Irvine * & J. Haugh n 

MeSH headings : Alginates / chemistry; Animals; Cell Surface Extensions / drug effects; Cell Surface Extensions / metabolism; Chemotaxis / drug effects; Dose-Response Relationship, Drug; Fibroblasts / cytology; Fibroblasts / drug effects; Fibroblasts / enzymology; Glucuronic Acid / chemistry; Hexuronic Acids / chemistry; Mice; Microspheres; NIH 3T3 Cells; Phosphatidylinositol 3-Kinases / metabolism; Platelet-Derived Growth Factor / chemistry; Platelet-Derived Growth Factor / pharmacology; Receptors, Platelet-Derived Growth Factor / metabolism; Signal Transduction / drug effects; Stochastic Processes
TL;DR: It is shown that persistent and properly aligned (i.e., high-fidelity) fibroblast migration does indeed correlate with polarized PI3K signaling; accordingly, this behavior is seen only under conditions of high gradient steepness and a certain range of PDGF concentrations.

Spontaneous phosphoinositide 3-kinase signaling dynamics drive spreading and random migration of fibroblasts

JOURNAL OF CELL SCIENCE, 122(3), 313–323.

By: M. Weiger n, C. Wang n, M. Krajcovic n, A. Melvin n, J. Rhoden n & J. Haugh n 

author keywords: Cell migration; Phosphoinositide 3-kinase; Integrin; Fibronectin; Adhesion
MeSH headings : Actins / antagonists & inhibitors; Actins / metabolism; Animals; Chemotaxis / physiology; Cytochalasin D / pharmacology; Cytoskeleton / metabolism; Fibroblasts / cytology; Fibroblasts / metabolism; Fibroblasts / physiology; Focal Adhesion Protein-Tyrosine Kinases / metabolism; Mice; Phosphatidylinositol 3-Kinases / metabolism; Platelet-Derived Growth Factor / metabolism; Pseudopodia / metabolism; Receptors, Platelet-Derived Growth Factor / metabolism; Signal Transduction / physiology
TL;DR: Live-cell imaging using total internal reflection fluorescence (TIRF) microscopy revealed that, in the absence of soluble cues, 3′-phosphoinositides are enriched in a localized and dynamic fashion during active spreading and random migration of mouse fibroblasts on adhesive surfaces.
