Immortalized SH-SY5Y cell lines expressing Trk-A or Trk-B. Control and parental cell lines also available.
Neuroblastoma (NB) is a tumor of the peripheral nervous system in children, and several receptor tyrosine kinase (RTK) genes have been implicated in malignant transformation or progression of these tumors, including ALK, NTRKs, RET, EGFR and IGFR. The Trk family of neurotrophin receptors (TrkA encoded by NTRK1, TrkB encoded by NTRK2, TrkC encoded by NTRK3) have been shown to play critical roles in regulating both favorable and unfavorable clinical behavior in NBs. TrkA is the receptor for nerve growth factor (NGF), and high TrkA expression is associated with clinically and biologically favorable tumors that have a propensity to undergo spontaneous regression or differentiation. TrkB is the cognate receptor for brain-derived neurotrophic factor (BDNF), and high expression of TrkB plus BDNF is found in the majority of high-risk NBs, especially those with MYCN amplification.
