Explore the cutting-edge research on preventing gastric cancer through genomic advancements in this 15-minute conference talk from the 2022 Gastric Cancer Summit. Presented by Dr. Hanlee Ji from Stanford University, delve into long-term objectives and the progression of integrative cellular genomics. Examine conventional gene expression techniques and study samples, comparing histopathology findings. Discover the power of spatial transcriptomics in cell mapping and localizing gene expression to specific cell types. Compare findings with gastric cancer cases and investigate gene mapping in relation to metaplasia, dysplasia, and cancer. Gain insights into gastric intestinal metaplasia analysis, epithelial cell type assignment, and cell mapping of metaplasia components. Conclude with a comprehensive summary of the research, acknowledging contributors and support for this groundbreaking work in gastric cancer prevention.
