As shown, of the various tumor pathological grades, the expression levels of SLC25A4 (P < 0.01), SLC25A11 (P < 0.0001), SLC25A24 (P < 0.01), SLC25A37 (P < 0.01), SLC25A42 (P < 0.01), SLC25A43 (P < 0.0001), SLC25A44 (P < 0.05) and SLC25A45 (P < 0.05) were significantly different (Fig. 1C). This evidence concerns the gene SLC25A42 and neoplasm.
