However, molecular mechanism of the cross-talk between Ntal and actin has not been studied. In this study we examined morphology, BI 6727 order actin cytoskeleton, migration and the activities of Rac and Rho, small Rho GTPases regulating actin cytoskeleton 12, following activation of WT and NTAL?/? BMMC by Ag and/or SCF. Our results provide the first evidence of a link between NTAL and the small GTPase RhoA and of its importance for regulation of mast-cell spreading and migration via actin polymerization. In accordance with a previous study 13, resting BMMC derived from WT mice adhered to fibronectin-coated glass poorly and did not spread, but after Ag challenge their adhesion increased and the cells spread. F-actin staining of resting BMMC revealed a strong subplasmalemmal actin cortex and some microvilli, while Ag-activated cells exhibited a more complex staining and ruffling (Fig. 1A). BMMC derived from NTAL?/? mice also exhibited an increased adhesion after Ag triggering, but their spreading, compared with WT cells, was noticeably reduced; a large subpopulation of unspread cells was present (Fig. 1B, Ag). Contrary to the Ag response, SCF induced comparable spreading and ruffling in both WT and NTAL?/? cells (Fig. 1B, SCF). When cells were activated with both Ag+SCF, spreading of WT cells was extensive, but that of NTAL?/? cells was again reduced (Fig. 1B, Ag+SCF). Quantitative assessment of spreading was obtained by measuring the cell area (the average number of pixels per cell). WT cells began to spread within 5?min following Ag stimulation, while the response was delayed in NTAL?/? cells (Fig. 1C, Ag). These data were Lapatinib ic50 supported by calculating the proportion of spread cells (Fig. 1D, Ag). Evaluation Vemurafenib of SCF-induced spreading confirmed that NTAL?/? and WT cells respond to SCF in a similar manner (Fig. 1C and D, SCF), indicating that SCF-induced cell spreading is NTAL-independent. However, when cells were stimulated with Ag and SCF simultaneously, the difference between spreading responses of WT and NTAL?/? cells was even more pronounced. Relative area of Ag+SCF-stimulated WT cells was significantly higher (p
