Figure 7. STAT3 silencing rescues the inhibitory effect of miR-126 on ESCC cell proliferation. STAT3 expression was detected in TE13 and Eca109 cells at both the protein (A, B) and mRNA (C, D) levels. STAT3i represents RNA knock-down of STAT3. (E, F) STAT3 knock-down affected the proliferation of TE13 and Eca109 cells.
