Design and selection ARTi-shRNAmirs.

(A) Sequence logo displaying nucleotide position biases of seed sequences (guide positions 2–8) with the lowest off-target score in siSPOTR analysis (top 1%). (B) Sequence logo displaying position …

Figure 2 with 3 supplements
Experimental validation of the artificial RNA interference (ARTi) approach.

(A) Schematic of EGFRdel19::V5::dsRed::ARTi engineering in PC-9 cells. Blue color denotes overexpressed ARTi variant. Green denotes endogenous gene. (B) Western blot demonstrating knockdown of EGFRde…

Figure 2—figure supplement 1
Validation of artificial RNA interference (ARTi) in vitro and in vivo – EGFR.

(A) Functional validation of the EGFRdel19 construct in Ba/F3 cells. Provided are GI50 values (nM) for indicated conditions and compounds (parental cells IL-3-dependent; other cells dependent on …

Validation of artificial RNA interference (ARTi) in vitro and in vivo – KRAS.

(A) Schematic of MIA PaCa-2 genome engineering. (B) AMG-510 GI50 values in MIA PaCa-2 parental and engineered cells. Numbers represent GI50 value calculated from three technical repeats. Three …

Figure 2—figure supplement 3
Validation of artificial RNA interference (ARTi) in vitro and in vivo – STAG1.

(A) Schematic of synthetic lethal interaction between STAG1 and STAG2. Cells survive loss of either paralog but are incapable of growing upon combined loss of STAG1 and STAG2. (B) Western blot …
