Expression of NRP-1 in gastric cancer tissues and cells. a-c Representative images of section from gastric normal mucosa (a), adenocarcinoma (b) and undifferentiated cancer (c), immunostained with an anti-NRP-1 antibody. d Lysates of human gastric cancer cells were immunoblotted. e The expression of NRP-1 mRNA was analyzed by qRT-PCR, and normalized to β-actin. f The expression of NRP-1 and NRP-2 was examined in lysates of parental MGC-803, MGC-803-Sc and MGC-803-SURlow cells by immunoblotting. NRP-1 expression in the three cell lines was further detected by immunohistochemistry
