Research Area
To investigate the features and molecular mechanisms underlying the metabolic reprogramming of tumors such as colorectal cancer, liver cancer, pancreatic cancer, glioma and breast cancer, uncover the regulatory roles of metabolic reprogramming in the growth, proliferation, death, and immune evasion of these tumors, identify tumor diagnostic biomarkers and therapeutic targets based on abnormal metabolism, and eventually collaborate with enterprises to develop corresponding novel methods and products for tumor diagnosis and treatment. Detailed research interests are as follows.
1. Mechanism of Pirin Protein in Promoting Tumor Immune Evasion and Immunotherapy Strategies with Pirin as a Target.
2. Identification of Novel Therapeutic Targets and Development of Treatment Strategies against IDH1/2 Mutant Tumors.
3. Mechanism of GLS1 Structural Remodeling and Development of Antitumor Drugs Targeting GLS1.
4. The Roles of Metabolic Alterations Caused by Proto-oncogene c-Src in Tumorigenesis and Metastasis.
5. The Roles and Molecular Mechanisms of Acetate Metabolism in Metabolic Diseases Including Tumor, Diabetes Mellitus and Cardiovascular Diseases.
