| Research Abstract |
There were significantly higher Tropomyosin-related kinase B (TrkB) and Brain-derived neurotrophic factor (BDNF) expressions in large cell neuroendocrine carcinoma (LCNEC) specimen than those in any other histological types. Furthermore higher expressions of TrkB and BDNF in resected specimen significantly correlated with advanced stage, postoperative recurrence, and poor overall survival. In vitro experiment, TrkB/BDNF signaling contributed to the invasiveness through MMP-2 and MMP-9 expressions. In addition, TrkB/BDNF signaling was involved in anchor-independent growth and tumorigenesis. These results suggest that TrkB/BDNF signaling may be a potential therapeutic target and a prognostic factor for LCNEC.
