Dissecting Expression Profiles of Gastric Precancerous Lesions and Early Gastric Cancer to Explore Crucial Molecules in Intestinal-type Gastric Cancer Tumorigenesis. Dissecting Expression Profiles of Gastric Precancerous Lesions and Early Gastric Cancer to Explore Crucial Molecules in Intestinal-type Gastric Cancer Tumorigenesis

To investigate the changes in molecular expression, biological processes, stemness, immune microenvironment, tumor hallmark activities and co-expression relationships during intestinal-type gastric cancer carcinogenesis and to excavate the prognostic information contained in the carcinogenesis process. RNA expression profiles of ninety-four gastroscope biopsy samples with different stages of precancerous lesions or early gastric cancers and their paired controls were detected by Agilent Microarray. Overall design: RNA expression profiles of ninety-four gastroscope biopsy samples with different stages of precancerous lesions or early gastric cancers and their paired controls were detected by Agilent Microarray.
