The aberrant expression of microRNAs and of the enzymes that control their processing has been reported in tumours, but the mechanisms involved are not clear. It is now shown that TAp63, a member of the p53 family of tumour suppressors, suppresses tumorigeneis and metastasis by directly controlling the expression of Dicer (a microRNA-processing enzyme) and Dicer-regulated microRNAs.
