(A and B)UBAP2 silencing decreased TMR-dextran uptake in pancreatic cancer cells. Top, silencing UBAP2 by siRNA or shRNA in pancreatic cancer cells including AsPC1 (A), Panc04.03 and PANC1 (B). Below are the corresponding, TMR-dextran uptake (red) assay indicated that depletion of UBAP2 decreased macropinocytosis. Nuclei (blue) were stained by DAPI. Scale bar, 10 μm. Bottom, Quantification of dextran uptake. Mean ± SD; **, p<0.01; *, p<0.05.
