autophagy regulation in synergy with phototherapy for breast cancer treatment.

Autophagy is an important factor in reducing the efficacy of tumor phototherapy (including PTT and PDT). Accurate regulation of autophagy in tumor cells is a new strategy to improve the anti-tumor efficiency of PTT/PDT. This project intended to construct a tumor-activated autophagy regulator to efficiently block PTT/PDT-induced autophagy and realize synergistic sensitization to tumor phototherapy.

A "bulldozer" driven by anoxic bacteria for pancreatic cancer chemo-immunotherapy.

Immune evasion is a major obstacle for pancreatic ductal adenocarcinoma (PDAC) therapy. Inhibition of autophagy can improve antigen presentation and enlarge immunogenic cell death (ICD) effect to generate a strong anti-tumor immune response. However, abundant extracellular matrix dominated by hyaluronic acid (HA) hinders the deep penetration of autophagy inhibitors and ICD inducers.

A self-guidance biological hybrid drug delivery system driven by anaerobes to inhibit the proliferation and metastasis of colon cancer.

Colorectal cancer is often accompanied by multiple organ metastasis. Anaerobic (BI) bacterial can selectively grow in hypoxic colorectal tumor microenvironment (TME), to own the natural advantage of preferentially colorectal tumor targeting. Herein, a self-guidance biological hybrid drug delivery system (BI-ES-FeAlg/DOX) based on BI was constructed to inhibit the proliferation and metastasis of colon cancer.
