ZEB1 and intestinal cancer: (107) showed that in intestinal cancer cells, the lncRNA RP11/hnRNPA2B1 (protein)/mRNA complex accelerated the degradation of Siah1 and Fbxo45 mRNAs, both of which encode ubiquitin E3 ligases, thereby preventing the proteasomal degradation of Zeb1, a transcription factor associated with EMT.
