Characterization of sli-siRNA-887. (a) Northern blot to detect the processed products from agsiRNA-887 that have extra bases on the 5′ or 3′ end in transfected HEK-293 cells. Ctrl, scrambled agsiRNA. U2 and U6 snoRNAs were used as RNA loading controls. (b) Northern blot to detect the processed products of base and loop modified agsiRNA-887 in transfected HEK-293 cells. U2 snoRNA was used as the RNA loading control. (c) Northern blot to detect the processed products of agshRNA-887 variants expressed by the U6m promoter in transfected HEK-293 cells. U6 snoRNA was used as the RNA loading control. (d) Northern blot to detect the processed products of stem variants of agshRNA-887 in transfected HEK-293 cells. Ctrl, scrambled agshRNA; S17, the wt agshRNA-887; mut, agshRNA-887 noncleavable mutant; U1, S17 driven by a modified U1 promoter; H1, S17 driven by a modified H1 promoter. All other agshRNAs were transcribed from U6m. U2 and U6 snoRNAs were used as RNA loading controls. (e) Northern blot to detect the processed products of stem variants of agsiRNA-887 in transfected HEK-293 cells. Ctrl, agsiRNA with a scrambled RNA sequence; S17, the wt agsiRNA-887; rsi, rsiRNA-887; si, siRNA-887. U2 and U6 snoRNAs were used as RNA loading controls. (f) Reporter assays of HCT-116 cells transfected with the agsiRNA-887 stem variants. Rluc/Fluc ratios are shown. Error bars represent the SD. (g) Northern blot to detect the processed products of agsiRNA-887 that have length variations in transfected HEK-293 cells. Ctrl, agsiRNA with a scrambled sequence; mut, agsiRNA-887-mut. The weak band in L38 was unintentionally caused by using only 1/10 of the molar concentration used for the others for transfection. U2 and U6 snoRNAs were used as RNA loading controls. (h) Reporter assays of HCT-116 cells transfected with agsiRNA-887 that have length variations. Rluc/Fluc ratios are shown. Error bars represent the SD.
