Figure 2. NUDCD1 knockdown inhibited the proliferation of PC cells. (A, B) The interference effects of three siRNAs on NUDCD1 were confirmed by qRT-PCR. (C–G) NUDCD1 knockdown inhibited the proliferation of PANC-1 and Patu8988 cells. (H–K) NUDCD1 knockdown inhibited the colony formation of Patu8988 and PANC-1 cells. (L–N) Western blot analysis showed that NUDCD1 knockdown decreased the expression of Ki-67 in PANC-1 and Patu8988 cells.**p<0.01, ***p<0.001, ****p<0.0001.
