Figure Lengend Snippet: ( A–B ) Knockdown of TAK1 by Map3k7 shRNA. ECA-109 cells were transduced with lentivirus bearing Map3k7 shRNA (LV- Map3k7 shRNA) or NC shRNA (LV-NC). 48 hr post-transduction, cells were harvested for analyzing TAK1 expression by quantitative real time-PCR (qRT-PCR) ( A ) and western blot ( B ). n = 3 biologically independent replicates. ( C–E ) Decreased expression of TAK1 facilitates cell migration and invasion. ECA-109 cells were transduced with LV- Map3k7 shRNA or LV-NC. 48 hr post-transduction, cells were subjected to transwell ( C, D ) or wound healing ( E ) assay. n=5 biologically independent replicates. Scale bar = 500 µm ( C ); scale bar = 100 µm ( E ). ( F – G ) Reduced expression of TAK1 increases mesenchymal marker expression and decreases epithelial marker expression. n=3 biologically independent replicates. ( H ) Reduced expression of TAK1 in ECA-109 cells affects epithelial-mesenchymal transition (EMT) related gene expression. Protein levels were analyzed by western blot, and Actin was used as a loading control. Gene expression was detected by qRT-PCR, and Gapdh was used as a house-keeping gene. n=4 biologically independent replicates. Data are presented as mean ± SD. Statistical significance was tested by unpaired Student’s t-test. *p<0.05, **p<0.01, and ***p<0.001. Figure 1—figure supplement 3—source data 1.
