Figure Legend Snippet: Figure 3: TM4SF1 and TM4SF5 but not TM4SF4 promoted enhanced transwell migration, and the TM4SF5 C-terminus could replace the pro-migratory effect of the TM4SF1 C-terminus. A. Cells incubated with 1% BSA-DMEM for 2 h were loaded (105 cells/condition) to the transwell chambers, the bottom sides of which were pre-coated with collagen I (10 μg/ml). After 10 h, cells that had migrated through the transwell chambers were stained with 5% crystal violet, and images were then acquired randomly; representative images are shown. B. The number of migrated cells from 10 random images per experimental condition were determined using an Image J software based on the intensity of staining. Values shown are the mean ± SD. Immunoblots for phospho-Tyr416 in c-Src and c-Src were performed using whole-cell lysates of the stable cells. *, **, and *** denote statistically significant differences at p <0.05, 0.005, or 0001, respectively, and ‘ns’ indicates a nonsignificant difference at p ≥ 0.05 by the ANOVA with Tukey’s post-tests. The data shown represent three independent experiments.
Techniques Used: Migration, Incubation, Staining, Software, Western Blot
Figure Legend Snippet: Figure 5: TM4SF5 and its C-terminus could positively replace the effects of TM4SF1 and TM4SF4 to promote invasive dissemination from spheroids embedded in 3D collagen I gels. A. Scheme of the ‘on-top’ 3D ECM-surrounded culture environment, in which the cells (red) were mixed with a lower concentration (yellow-pink) of collagen I gel (0.2 mg/ml) and overlaid on the bottom dense layer with collagen I gel at a higher concentration (blue, 2 mg/ml) that was previously solidified. B to E. Representative images of the starting (each left) and ending (each right) points of the live-imaged spheroids in each condition were shown (B and E). The two-tailed unpaired Student’s t-test was used for the analysis in (B). * denotes statistically a significant difference at p <0.05, but ‘ns’ insignificantly at p ≥0.05. The dissemination initiation times (C) or numbers of cells disseminating (D) from the spheroids were measured during the live- imaging for 36 (C) or 24 (D) h and are presented in the graph as mean ± SD values. White arrow heads depict the disseminating cells (B). Immunoblotting for phospho-Tyr397 in FAK and FAK was performed by using the whole cell lysates prepared from the spheroids in 3D collagen I gels. PP2 or PP3 (10 μM) was added to the gels during the embedding processes, before 24 h live-imaging (E).
