Messenger RNA (mRNA) stability is regulated mainly by proteins that bind sequences enriched in adenine and uracil in their 3´untranslated regions, called AU-binding proteins (AUBPs). Tristetraprolin (TTP) is an AUBP that promotes mRNA degradation of proteins involved in inflammation, proliferation and tumor invasiveness. In particular, RNA-seq data indicates that TTP is up-regulated in mammary progenitor cells (p
