MiR-199b-5p, which has a very similar nucleotide sequence, is also predicted to target DDR1. However, miR-199b-5p was only detectable in four out of 24 tissue samples in a miRNA microarray assay (data not shown) and it has never been reported to be de-regulated in HCC in literature. The gene discussed is DDR1; the disease is hepatocellular carcinoma.
