The Cre-mediated deletion of the <i>p44</i> gene in prostate epithelial cells.

<p>(A) A diagram illustrating the procedure to generate <i>p44-null</i> (p44^−/−) epithelial cells from the mouse whole prostate. (B) Epithelial cells were stained for CK5 and CK18 as indicated. The nucleus was stained with Sytox green. (C) Western blot analysis of whole cell lysates (10 µg) made from LNCaP (lane 1) or prostate epithelial (lane 2) cells analyzed with anti- AR, -p63, -p44, or -actin antibody as indicated.
