The role of nerve growth factor and its receptors in tumorigenesis and cancer pain.
Wang WF, Chen JH, Guo XL
The nerve growth factor (NGF) is a growth factor that belongs to the neurotrophin family. NGF has two structurally different receptors, the p75 neurotrophin receptor (p75NTR) and the tropomyosin-related kinase A (TrkA). Interaction of NGF with its receptors regulates a variety of physiological processes of neuronal system. Recent studies have shown that NGF and its receptors were involved in the regulation of tumourigenesis by either supporting or suppressing tumor growth depending on the tumor types. This review summarizes the current views of NGF and its receptors in tumorigenesis and cancer pain.
