Representative blots revealing the protein levels of p-STAT3, STAT3, MMP2, MMP9, cleaved caspase-9, and caspase-9 in (A) SiHa and (B) HeLa cells transfected with oe-B2R, sh-B2R, or an empty lentiviral vector. GAPDH was loaded as a control. The results were similar for three independent experiments. p-STAT3, phosphorylated-STAT3; B2R, bradykinin B2 receptor; MMP, matrix metalloprotease.
