Comparison of L sshRNA activity with various loop structures and base pairs adjacent to the loop. (A) Loop length comparison, using L sshRNAs against the same target region as sh68 and si19-3, but with various lengths and sequences of loops. sshRNAs were chemically synthesized and their abilities to inhibit HCV IRES-dependent luciferase expression were compared in 293FT cells. (B) Loop-adjacent base-pair comparison. sshRNAs against the same target region as si72, but with loops of 5 nt (SG72 and SG72L) and 2 nt (SG118 and SG103) and left-loop (SG72L and SG118) and right-loop (SG72 and SG103) orientations were compared for their inhibitor activity in 293FT cells. Loop sequences are underlined.
