Suppression of dynein subunit expression using siRNA. Immunoblots show control suppression of lamin A/C from the same experiment, GAPDH as a loading control and the results of transfection with two independent duplexes targeting (A) dynein-1 heavy chain (DYNC1H1), (B) IC2 (DYNC1I2), (C) LIC1 (DYNC1LI1) and LIC2 (DYNC1LI2), (D) Tctex1 (DYNLT1) and rp3 (DYNLT3), (E) LC8 (DYNLL1), and (F) dynein-2 heavy chain (DYNC2H1). Inclusion of duplexes targeting isoforms that are not expressed in these cells provides an additional control and reinforces the specificity of our knockdowns.
