  • * Assessed with various antibodies from the following publications: Murray et al. (5) and McFadyen et al. (4), which are not sensitive enough to detect CYP1B1 in normal tissues.

  • Assessed with a highly sensitive antibody developed by Tang et al. (6).

  • Expression was moderate to high in most grade 2 and 3 breast cancers.
