As for ADAR and stromal cells, Takeda et al. reported that both ADAR1 expression and AZIN1 RNA editing levels were significantly elevated in colorectal cancer (CRC) tissues vs. normal mucosa, and these findings correlated with the increased expression of mesenchymal markers, vimentin and fibroblast activation protein. The gene discussed is AZIN1; the disease is colorectal carcinoma.
