Quantitative analysis of mammary tumor cell proliferation and apoptosis during 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary carcinogenesis in rats in the presence or absence of pomegranate emulsion (PE). Effects of PE on intra-tumor PCNA LI as determined by immunohistochemistry (A) and apoptotic index (AI) as measured by DNA fragmentation assay (B). The labeling index (LI) or AI was expressed as the number of immunopositive cells 100×/total number of tumor cells analyzed. Results are expressed as mean ± SEM (n = 4). *P < 0.001 compared with DMBA control.
