| Outline of Final Research Achievements |
Breast cancer incidence has been increasing in Japan, which gives us urgent issues of the investigation for the critical cause of breast cancer and the establishment of its chemoprevention. First, we conducted a screen for compounds which inhibited the growth of ERalpha-positive breast cancer cells, and found three hit compounds which reduced the expression level of cyclin D1. Second, we identified the inner mitochondrial membrane protein ANT2 as a common binding protein of these compounds. Finally, we suggested that ANT2 pleiotropically regulated the expression level of cyclin D1 at mRNA and protein levels. Taken together, ANT2 is expected to be a promising target against cyclin D1-overexpressing cancer, including breast cancer.
