<p>1×10<sup>6</sup> cells transfected with control (mice 1–4) or Src+STAT3 siRNAs (mice 5–8) were implanted into the mammary fat pad of mice. After 66 days, the tumors were excised and weighed (significant differences are indicated (*; p<0.05)(<b>A</b>). Sections of the tumor were stained (<b>B</b>) or subjected to immunostaining with anti-GFP antibody (<b>C</b>). Malignant cells are indicated by an arrow. A portion of each tumor was homogenized with RIPA buffer and immunoblotted with anti-GFP antibodies (<b>D</b>).</p
