miR-200 expression in 55-day old control and MTB-200ba429 transgenic mice. (A) Expression of miR-200b, miR-200a, miR-429, miR-200c or miR-141 in virgin mammary glands from MTB-200ba429⁺ transgenic mice or control mice as determined by qRT-PCR, n = 3. (B) in situ hybridization for (B,C) miR-200b or (D,E) miR-200c in (B,D) control mammary glands or (C,E) mammary glands from MTB-200ba429+ mice. Positive staining for miR-200b or miR-200c appears red while the sections were counterstained with Gill's hematoxylin. Scale bars are 60 µm. ** indicates p < 0.01 and **** indicates p < 0.0001(For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.).
