Data format	Analyzed
Experimental factors	Before LC-ESI-MS/MS, the proteins were labeled with iTRAQ reagents.
Experimental features	The authors used iTRAQ labeling combined with LC-ESI-MS/MS analysis to identify differentially expressed proteins in gastric cancer tissues.
Data source location	Gastric cancer and adjacent normal tissues were selected from the tissue bank at the Departments of Pathology, Affiliated Traditional Medicine Hospital of the Southwest Medical University, Luzhou, Sichuan 646000, P. R. China.
