A: Design of ret/PTC1 small interfering RNAs (siRNAs). Location of ret/PTC1 sense sequence of siRNA nos. 1, 2, 3, 4 and 5 examined in this study are shown under the junction sequence of ret/PTC1. The ret part of the oncogene is presented on the right part (▪). B: The control sequence is the sequence #5 with four mismatches. Mismatch site is shown in boxes. C: Structure of the shRNA1 and negative control shRNA.
