Correction
It has come to our attention that since publication of our article [1], in the body of the article the term androstenedione has been used in error. The experiments in this study used androstanedione as a test substrate. Androstenedione was not used in any experiments. This error does not in any way invalidate the conclusion of the paper that aldo-keto reductases of the mouse and human 1C-subfamilies lack functional and expression homology. The authors apologise for any confusion caused.
