VASP may be involved in the pathophysiology of bronchopulmonary dysplasia via dysregulation of actin binding proteins
VASP role in the actin filament elongation
Our results reveal a dual role of VASP in endothelial permeability. In addition to its well-documented function in barrier integrity, we show that S-nitrosylation of VASP contributes to the onset of endothelial permeability.
findings have uncovered a PKG/VASP signaling pathway in Vascular Smooth Muscle Cells as a key molecular mechanism underlying T3-induced vascular relaxation.

VASP, zyxin and TES are tension-dependent members of focal adherens junctions independent of the alpha-catenin-vinculin module.
Data show that the phosphorylation status of vasodilator-stimulated phosphoprotein (VASP) at serine S322 can be predictive for breast cancer progression to an aggressive phenotype.
The authors propose that Lpd delivers Ena/VASP proteins to growing barbed ends and increases their actin polymerase activity by tethering them to actin filaments.
Data show that tumor necrosis factor-alpha (TNF-alpha) increased A549 lung adenocarcinoma cell permeability by repressing vasodilator-stimulated phosphoprotein (VASP) expression through the activation of hypoxia inducible factor 1 alpha subunit (HIF-1alpha).
The authors demonstrate that vasodilator-stimulated phosphoprotein (VASP), which is critical for regulation of actin assembly, cell adhesion and motility, is a direct substrate of Yersinia pestis YpkA kinase activity.
Ena/VASP's ability to bind F-actin and profilin-complexed G-actin are important for its effect, whereas Ena/VASP tetramerization is not necessary.
In clinical practice,LCR and CYP2C19 gene polymorphism should be assessed in NCIS patients receiving clopidogrel treatment.
VASP phosphorylation at Ser(157) mediates its localization at the membrane, but that VASP Ser(157) phosphorylation and membrane localization are not sufficient to activate its actin catalytic activity
PKA regulates VASP phosphorylation in Ras-transformed cells in a non-cell-autonomous manner.
Serine phosphorylation of vasodilator-stimulated phosphoprotein (VASP) regulates colon cancer cell survival and apoptosis.

VASP selectively mediate activated T-cell trafficking by promoting the diapedesis step of transendothelial migration in a alpha4 integrin-dependent manner.
We identified a phosphorylation-dependent mechanism that regulates selective recruitment of these effectors to Lamellipodin: Abl-mediated Lamellipodin phosphorylation promotes its association with both Scar/WAVE and Ena/VASP, whereas Src-dependent phosphorylation enhances binding to Scar/WAVE but not to Ena/VASP
Thus, unlike host proteins characterized in Shigella pathogenesis that promote bacterial spread, VASP and EVL function to limit it.
Data show that the hypoxia inducible factor 1 alpha subunit (HIF-1alpha) protein level in lung tissues increased significantly at four hours and eight hours, whereas the vasodilator-stimulated phosphoprotein (VASP) protein level decreased significantly.

VASP binding to actin, elevated Rac activity, and elevated formation of actin free barbed ends, thus restoring normal beta(2) integrin function.
Growth of VASP expressing melanomas was retarded in VASP(-/-) versus wild-type animals
Vasodilator-stimulated phosphoprotein (VASP) is a member of the Ena-VASP protein family. Ena-VASP family members contain an EHV1 N-terminal domain that binds proteins containing E/DFPPPPXD/E motifs and targets Ena-VASP proteins to focal adhesions. In the mid-region of the protein, family members have a proline-rich domain that binds SH3 and WW domain-containing proteins. Their C-terminal EVH2 domain mediates tetramerization and binds both G and F actin. VASP is associated with filamentous actin formation and likely plays a widespread role in cell adhesion and motility. VASP may also be involved in the intracellular signaling pathways that regulate integrin-extracellular matrix interactions. VASP is regulated by the cyclic nucleotide-dependent kinases PKA and PKG.
