RNA editing levels of ARHGAP26 transcript in its 3′ UTR in different human cells. Twelve known A-to-I RNA editing sites of the ARHGAP26 transcript in its 3′ UTR are named U1–U12, starting from the 5′ to the 3′. They were analyzed in SW480, Raji, DU145, U2OS, A549, MCF-7, MCF-10A, HepG2, and Chang liver cells by comparing the sequences of RT-PCR products with the corresponding genomic templates. The editing level was defined to be the ratio of the G peak over the sum of the G and A peaks in the sequencing chromatogram.
