Figure 3. Knockdown of syncytin-1 reduced the fusion between SCC-9 and HUVEC.

Figure 3

(a,b) The efficiency of four different sh-RNA sequences (sh-RNA1, 2, 3, 4) targeting syncytin-1 and negative sh-RNA sequence which was used as negative control by qRT-PCR and western blot. (c) The number of fused cells between SCC-9 and HUVEC when syncytin-1 in SCC-9 was knocked down by sh-RNA by number counting. (d) The rate of cell fusion between SCC-9 and HUVEC measured by FACS. When co-cultured SCC-9 whose syncytin-1 was knocked down by sh-RNA with HUVEC, the fusion rate could be 0.196 ± 0.008% compared to the negative control group, 0.768 ± 0.012%. (e) The statistical analysis of FACS.
