Genetic status of KRAS modulates the role of Neuropilin-1 in tumorigenesis
Abstract Neuropilin-1 (NRP1), a non–tyrosine kinase receptor, is overexpressed in many cancers including pancreatic and lung cancers. Inhibition of NRP1 expression, however, has differing pro-tumor vs. anti-tumor effects, depending on the cancer types. To understand the differential role of NRP1 in...
