  • a Based on data from the 2,180-microarray database compiled in GENEVESTIGATOR. Tissue signals that are significantly higher than background (P ≤ 0.06) are indicated. Experiments are summarized in (Zimmermann et al., 2004).

  • b Induction of more than 2-fold or, where indicated, repression by 0.5-fold and above 200 in the relative signal value are indicated.
