The results are shown in Figure 1, where CD inhibits the NRP1 expressions in both the protein and the mRNA in dosage-dependent manners in the H1975 cells (Figure 1A,B), the BT549 cancer cells (Figure 1C,D), the PC3 prostate cancer cells (Figure 1E,F), and the 22RV1 prostate cancer cells (Figure 1G,H), respectively. This evidence concerns the gene NRP1 and Familial prostate cancer.
