All blots were normalized to GAPDH levels. * p < 0.05 vs. NCI‐H345 cells. VEGF, vascular endothelial growth factor; VEGFR2, vascular endothelial growth factor receptor 3; p, phosphorylated

Article Snippet: The levels of VEGF, VEGFR2, and pVEGFR2 in NCI‐H345 and NCI‐H446 cells were examined by Western blot analysis to select the ideal cell model. NCI‐H345 and NCI‐H446 cells were subsequently treated with 30 ng/ml recombinant human VEGF (rhVEGF; cat. no 10542‐H08H; Sino Biological) for 0, 30, 60 and 120 min at 37°C.

Figure Lengend Snippet: Following ectopic expression of untagged NRP2B in C4–2B cells, nuclear and post-nuclear fractions were separated, and a pull-down assay was performed on the nuclear fraction with NRP2 antibody. Mass-Spectrometry was carried out with the pull-down samples. Using the genes detected in NRP2 Mass-Spectrometry. A. Sum of all the spectra associated with NRP2B pulldown sample is determined by the spectral graph. B. Venn-diagram represent the overlapping genes identified in two independent NRP2B mass-spectrometry assay. C. Group of nuclear pore proteins (Nups) identified through NRP2B Mass-Spectrometry. Schematic diagram indicating the relative positions of Nups around the nuclear pore. D. Validation of NRP2-Nup93 interactions in C4–2B. C4–2B cells were transfected with HA-tagged NRP2B. IP was carried out with HA-antibody and immunoblots were carried out with anti-Nup93. E. Endogenously, NRP2 and Nup93 interaction was validated in C4–2B and 22Rv1 cell lines. NRP2 was pull down with NRP2-specific antibody and IB with Nup93 antibody. F. NRP2B and AR interaction was carried out in C4–2B following ectopic interaction of HA-tagged NRP2B. Pulldown was carried out with HA-antibody and IP was carried out against NRP2 and AR. G. NRP2 and AR interaction was also monitored in PC3 and 22Rv1 following ectopic expression of HA-tagged NRP2B. IB was carried out against HA and AR. H. Co-IP for AR with NRP2 was carried out with pulldown of NRP2 by HA-antibody in C4–2B cells expressing wild type and mutant K892A NRP2B isoforms. NRP2B immunoblot was carried out with HA-antibody. I. IP with AR antibody was carried out to test the interaction among AR, Nup93 and NRP2 under the presence or absence of NRP2 and Nup 93 from the nuclear fraction of LNCaP C4–2B cells. An immunoblot was performed with anti-AR, anti-Nup93 and anti-NRP2 antibody. The Co-IP was carried out in the presence of 50ng/ml VEGF-C. J. PLA was carried out to validating the NRP2-AR interaction within the nucleus. Following ectopic expression of HA-tagged NRP2B, PLA was carried out with HA and endogenous AR antibodies under the presence or absence of NUP93. As a negative control, only HA-antibody was used for PLA reaction. Arrowhead indicates the immune-reactive PLA puncta. Nucleus was counter-stained with NUP98 to demarcate the nuclear periphery. DAPI used for nuclear staining. PLA quantification was shown in Bar diagram.
