Chemoprevention of 7,12-dimethylbenz(a)anthracene (DMBA)-initiated rat mammary tumorigenesis by pomegranate. Effects of pomegranate emulsion (PE) on the size of mammary tumors (A–D), intratumor histopathological profiles (E–H), cell proliferation (I–L), apoptosis (M–P), Bax (Q–T), and Bcl2 (U–X) protein expression. The rats were treated with oral PE 2 wk prior to and 16 wk following DMBA administration. All animals were sacrificed 16 wk following DMBA exposure. The mammary tumors were subjected to morphological observation as well histopathological (H&E) and immunohistochemical analysis using anti-PCNA, anti-Bax, and anti-Bcl2 antibodies. Apoptosis was detected by DNA fragmentation assay. Magnification: 100× for tumor and H&E and 200× for PCNA, apoptosis, Bax, and Bcl2.
