Effects of KRAS knockdown in CRC cell lines. (A) Quantitative RT-PCR showing relative mRNA levels for KRAS. HCT116 cells (left) and DLD-1 cells (right) were treated separately with two independent siRNA constructs (#1 and #2) targeting KRAS and NC siRNA. Mean; bars, ± SD, n = 3 (Student's t test; *P < .05). (B) Western blot photographs of KRAS, ASNS, and β-actin (Actin). HCT116 cells were treated separately with two independent siRNA constructs (#1 and #2) targeting KRAS and NC siRNA.
