ADARB1 and cancer: We chose mesothelial cells (SDM104), ADAR2 low cells (ACC Meso1, SPC111, SPC212), and ADAR2 high cells (Mero95, ONE58) and determined RNA editing levels of the codon I164V of Coatomer Protein Complex subunit α (COPA) mRNA, a specific ADAR2 substrate [44], also part of the 8 differentially edited sites recently described in cancer [43].
