Intratumoral microbiota have been identified as a component of the tumor microenvironment that regulates metastatic behavior tumors. They serve not only indicators pathology but also potential drug targets in cancer therapy. Herein, multifunctional nanoplatform (DD@FEL) is prepared by combining antibiotic doxycycline (DOXY) can combat intratumoral and chemotherapeutic doxorubicin (DOX) ergosterol-originated liposome. Specially, ergosterol utilized substitute for cholesterol liposomes to exert pharmacological activity. Mechanistically, DD@FEL leveraged DOXY inhibit metastasis based on regulation microbiota, which synergizes with effect DOX, eventually inhibiting progression triple-negative breast (TNBC). Verified both vitro vivo, effectively exerts cytotoxic TNBC cells, delays growth primary TNBC, attenuates development its lung metastasis, providing promising therapeutic strategy control orthotopic TNBC.
