Erratum to: From carrot to clinic: an overview of the retinoic acid signaling pathway

Erratum to: Cell Mol Life Sci DOI 10.1007/s00018-010-0268-z

During the editing process, a few chemical structures in Fig. 1 were reproduced incorrectly: a double bond was shifted in the structure of β-carotene (Fig. 1a), two methyl groups were cut from the hexane ring of 5,8-epoxy-all-trans retinoic acid (Fig. 1a) and, lastly, a carboxylic acid group (COOH) was missing from the BMS614 structure (Fig. 1b). The corrected structures have now been incorporated into Fig. 1.
