Research on Early Diagnosis and Clinical Transformation of Nuclide Probe Based on Bioorthogonal-gastric Cancer Mucin Target Visualization

Recruiting now · Not applicable

Conditions studied: Solid Tumor

In brief

The symptoms of early gastric cancer are extremely insidious and most patients are identified as advanced at the time of initial diagnosis. Starting from the clinical needs, this project selects solid tumors and pathogenic glycoprotein synthesis of key glycopeptide antigen determinant mucin (MUC) family of multiple molecules as the research object. Based on the digestive system tumor research cohort established in the early stage, this project intends to verify the tumor microenvironment characteristics of the MUC family and gastric cancer treatment resistance through immunohistochemistry, COSMC gene sequencing and other technologies, and screen key MUC family proteins. Based on the discovery of differential recognition of COSMC deficient cells by antibodies, MUC1-targeted specific monoclonal antibody was developed. Further development of spatial mucinomics based on laser ablation inductively coupled plasma mass spectrometry (LA-IPC-MS) and spatial metabolome based on desorption electrospray mass spectrometry (DESI-MS) to analyze the structure and immunosuppressive mechanism of key gastric cancer glycoprotein MUC. After obtaining key targeted antibodies, with the help of biological orthogonal and click chemistry technology, the original clinical translational research based on mucin targeting was carried out, and a high-affinity nuclide conjugate drug (RDC) with "triple binding" of gastric cancer mucin was constructed and clinical translational research was carried out, which provided new ideas for the accurate diagnosis and treatment of gastric cancer in the early stage.
