First, although the mRNA expression of Drp1 was verified on the basis of the data from the TCGA and GEO public databases and the protein expression of Drp1 by immunohistochemistry experiments, further experiments must be conducted to explore the molecular mechanisms associated with Drp1 and the mechanism by which Drp1 regulates the tumor-infiltrating cells to affect the prognosis of patients with GC. This evidence concerns the gene DNM1L and neoplasm.
