'Sorry, We're Illiterate'

By the way, although Dr. Jekyll has already mentioned it, this is one of the funniest retractions I've ever read:

In this Article, the messenger RNA that is identified to be a target of microRNA-23 (miR-23) is from the gene termed human 'homolog of ES1' (HES1), accession number Y07572, and not from the gene encoding the transcriptional repressor 'Hairy enhancer of split' HES1 (accession number NM_00524) as stated in our paper.

(Translation: We can't read. Wow, do we feel stupid now.)
