Abstract Gastric cancer is one of the most malignant digestive tract tumors worldwide and its progression is associated with gene expression and metabolic alteration. We revealed that the gastric cancer patients with lower expression level of TOB1 exhibited poorer overall survivals according to the data in Kaplan–Meier Plotter. The unphosphorylated TOB1 protein which is effective expressed lower in gastric cancer cells. The gastric cancer cells with TOB1 gene depletion performed higher abilities of proliferation, migration and invasion and lower ability of apoptosis in vitro. The TOB1 gene depletion also promoted the tumorigenesis of gastric cancer cells in vivo. The gastric cancer cells with TOB1 gene overexpression had the converse behaviors. The transcriptional and metabolic sequencing was performed. The analyzation results showed that genes correlate-expressed with TOB1 gene were enriched in the pathways related to ERK pathway, including focal adhesion pathway, which was verified using real-time quantitative PCR. After inhibiting ERK pathway, the proliferation, colony formation and migration abilities were reduced in gastric cancer cells with low phosphorylated TOB1 protein expression level. Moreover, Pearson correlation analysis was adopted to further analyze the correlation of enriched metabolic products and differentially expressed genes. The expression of Choline, UDP-N-acetylglucosamine, Adenosine and GMP were related to the function of TOB1. This study demonstrates the genes and metabolites related to focal adhesion pathway and ERK pathway are the potential diagnosis and therapeutic targets to gastric cancer with TOB1 depletion. |
