AHRR and neoplasm: Table 1 shows the list of tumor-associated genes and their ARE sequences subjected to TTP-mediated mRNA degradation. The data indicate that TTP’s target mRNAs during tumorigenesis are predominantly oncogenes as opposed to tumor suppressors; 21 oncogenes were targets, as compared to three tumor suppressor genes, such as cyclin-dependent kinase inhibitor 1 (CDKN1A), large tumor suppressor kinase 2 (LATS2), and aryl-hydrocarbon receptor repressor (AHRR) [22,23,24].
