In order to understand the effect of MCU on recurrence and metastasis in gastric cancer patients, we detected the expression of MCU in patients with recurrence and metastatic gastric cancer after treatment, and found that MCU was highly expressed in the cancer tissues of patients with recurrent and metastatic gastric cancer, indicating that MCU may be associated with recurrence and metastasis of gastric cancer (P< 0.05), see Figure 2E. Here, MCU is linked to gastric cancer.
