Electroacupuncture promotes apoptosis and inhibits axonogenesis by activating p75 neurotrophin receptor for triple-negative breast xenograft in mice

•Electroacupuncture inhibited axonogenesis in tumor microenvironment.•Electroacupuncture restrained tumor growth and promoted cell apoptosis in breast tumor-bearing mice.•p75NTR is a key target of the tumor suppressive effect of electroacupuncture.
