Fig 4. The ectopic expression of α-1,2 fucosyltransferase FUT1 inhibits invadopodia in WM793 cells.
A, comparing the expression levels of FUT1 and FUT2 mRNA in normal skin, benign nevi, primary melanoma and metastatic melanoma in five microarray datasets. B, the ectopic expression of Flag-FUT1, as determined using anti-FLAG Western blotting. C, representative invadopodia assay images showing the effect of ectopically expressed FUT1 on invadopodium formation and gelatin degradation in WM793 cells D and E, quantitation of the effect of ectopically expressed FUT1 on the invadopodium number per cell (D) and the proportion of invadopodia positive cells (E) WM793. F and G, representative images (F) and quantitation data showing the effects of FUT1 overexpression in WM793 cells on Matrigel invasion. *, *** and **** indicates p< 0.05, 0.001 and 0.0001, as determined by two-tailed, two sample t-test (A, D, G) or two-tailed Fisher’s exact test (E). Numbers in parentheses indicates the number of cells used in quantitation. Representative results from at least three independent replicates were presented.
