It is important to mention that this event may be a result of the disruption of many cell surface chondroitin sulfate proteoglycans, such as syndecans, chondroitin sulfate proteoglycan 4, betaglycan, neuropilin-1, receptor protein tyrosine phosphatase, integrin and VEGFR-2, which were also previously demonstrated to be overexpressed in cancer [39]. Here, NRP1 is linked to cancer.
