Gastric cancer is the most common malignant tumor of the digestive system. The etiology of gastric cancer is complex, and susceptibility at the genetic level remains to be fully elucidated in genetic investigations. In the present study, mutations of the cell cycle checkpoint kinase 2 (CHEK2) gene and its association with gastric cancer were examined. Reverse transcription‑quantitative polymerase chain reaction technology was used to detect the expression of CHEK2 and it was found that the expression of CHEK2 was low in gastric cancer. Using sequencing analysis, it was found that the low expression level of CHEK2 was associated with expression of its mutation. The present study also established a CHEK2‑overexpressing mutant and confirmed that CHEK2 promoted gastric cancer cell proliferation. Overexpression of the CHEK2 mutation was confirmed to promote cancer cell migration and invasion. Furthermore, western blot analysis results revealed that overexpression of the CHEK2 mutation downregulated E‑cadherin and upregulated vimentin expression, indicating the mechanism underlying the altered biological behavior. These results suggested that there was a correlation between mutation of the CHEK2 gene and gastric cancer, and provided an experimental basis for antitumor drug investigation and development according to its mutation target.
