Figure 4From: MiR-339-5p inhibits breast cancer cell migration and invasion in vitro and may be a potential biomarker for breast cancer prognosis Expression of miR-339-5p in breast tissue specimens. Paraffin blocks from breast cancer or benign tissue specimens were prepared for making tissue microarrays, and the sections from the latter were hybridized with miR-339-5p probe in situ hybridization. A. Positive expression of miR-339-5p in a breast fibroadenoma. B. Positive expression of miR-339-5p in an invasive ductal carcinoma without lymph node metastasis. C. Negative expression of miR-339-5p in an invasive ductal carcinoma with lymph node metastasis. D. Negative control probe in an invasive ductal carcinoma. Magnification: ×200.Back to article page
