Perineural invasion (PNI) represents a uniquely distinctive pathway for tumor metastasis, but its underlying molecular mechanisms and therapy remain unclear. Bioinformatics analysis and transcriptomic sequencing were first employed to investigate the involvement of the BDNF/TrkB axis in the ESCC PNI, which was validated with ESCC cells co-cultured with a dorsal root ganglia system (ESCC/DRG model), a mouse PNI model, and ESCC tissues, mainly using microscopic imaging, IVIS Spectrum The BDNF/TrkB axis is closely associated with the PNI in ESCC. This pathway plays a pivotal role in driving PNI progression via Akt signaling. Deguelin was identified as an effective inhibitor of PNI in ESCC. Mechanistically, BDNF was revealed to be a key binding target of Deguelin, which disrupts PNI development by modulating the BDNF/TrkB/Akt axis. Notably, overexpression of BDNF can counteract Deguelin's inhibitory effects on ESCC growth and PNI progression. The BDNF/TrkB axis promotes the progression of ESCC PNI, and Deguelin inhibits ESCC PNI by targeting this axis, enhancing the understanding of PNI's molecular mechanisms and offering new therapeutic options.
