Since miR-16 regulates COX-2 expression by binding to the MRE in the 3′-UTR COX-2 and by inhibition of HuR in HCC cell lines, we evaluated the relationship between miR-16, HuR and COX-2 mRNA/protein expression in individual tumoral (T) and paired non-tumoral (NT) HCC human samples. The gene discussed is ELAVL1; the disease is hepatocellular carcinoma.
