Fourteen isoforms of NRP1 were differentially expressed in tumor tissues (Supplementary Figure S10B), Usage of the isoform ENST00000374875.5 (NRP1-002) was the highest among all the isoforms, followed by the isoform ENST00000374867.6 (NRP1−202) (Supplementary Figure S10B). This evidence concerns the gene NRP1 and neoplasm.
