Integrin extension enables ultrasensitive regulation by cytoskeletal force. J Natl Cancer Inst. Descriptive statistics were calculated for all the variables. Depletion of hMENA t resulted in abrogation of stress fiber, actin reorganization, and a dramatic cell shape change Supplementary Figure 2b. The correlation analysis was performed with Spearman test.

An integrin-linked machinery of cytoskeletal regulation that enables experimental tumor initiation and metastatic colonization.
The fold reduction of phoshorylated protein expression in hMENA 11a -expressing clones is reported on the right. Introduction In order to invade, cancer cells rely on a dynamic remodeling of actin cytoskeleton [ 1 — 3 ].

Mena invasive MenaINV promotes multicellular streaming motility and transendothelial migration in a mouse model of breast cancer. In contrast, hybMENA 11a -positive tumors express essentially a low FN1 level in the stroma, in agreement with the proteomic data obtained for cancer cell lines.
The VASP tetramerization domain is a right-handed coiled coil based on a residue repeat. We have demonstrated previously that the alternatively spliced hMENA isoforms impact cytoarchitecture [ 10 ] and are linked to malignant progression in a 3D model of human breast cancer progression [ 14 ].

Metastatic growth from dormant cells induced by a col-I-enriched fibrotic environment. In primary tumors high hMENA 11a correlates with low stromal fibronectin and a favorable clinical outcome of early node-negative non-small-cell lung cancer patients.
Cell invasion assay Cell invasion assay was performed axxis previously reported [ 10 ] in Matrigel invasion chamber BD Biocoat Matrigel invasion chamber, BD Biosciences in serum-free medium, or in serum-free medium containing 0.
Context, tissue plasticity, and cancer: Linking actin dynamics and gene transcription to drive cellular motile functions. Moreover, among the significantly reduced secreted proteins we found the colony-stimulating factor 1 CSF1in agreement with previous data in MTLn3 mammary tumors reporting that increased MENA 11a expression correlates with decreased expression of CSF1 [ 42 ].
