Figure 4. STAT3 is the target gene of miR-29b.

(A) Relative luciferase activity of the indicated STAT3 reporter construct in cervical cancer cells, co-transfected with miR-29b mimic or scramble mimic, is shown; (B) Quantitation RT-PCR of the expression level of STAT3 mRNA in cervical cancer cells treated with miR-29b mimic; (C) Western blot analysis showed the expression level of STAT3 and its downstream protein in CC cells treated with miR-29b mimic.
