Core Tip

Core Tip: Gastric cancer (GC) is one of the most common malignancies of the digestive system with few genetic markers for its early detection and prevention. 348 GC tissues and 141 normal tissues were analyzed in this study; 251 differentially expressed genes (DEGs) were identified including 187 down-regulated genes and 64 up-regulated genes. Significantly upregulated genes with a poor prognosis in GC were detected using integrated bioinformatics methods. Furthermore, the molecular mechanism of GC via bioinformatics analysis showed three DEGs (BIRC5, TRIP13, or UBE2C) which play key roles in the progression of CG.
