NRP1 and neoplasm: Indeed, an interaction between miR-200 family and NRP1 3’UTR has been previously demonstrated by luciferase reporter experiments and Western blot assays in embryonic stem cells [54], but to date still little is known about the upstream miRNAs regulating NRP1 in OC and the molecular mechanisms by which miRNAs/NRP1 axis modulates drug resistance in this tumor.
