Table 1.

Statistical table of tissues stained with SLC22A6, SLC22A7, SLC22A13, SLC25A4, SLC34A1, and SLC44A4. All slides were retrieved from the HPA. Compare the expression level in cancer and normal tissue from the aspects of staining, intensity, and quantity. P < 0.01 meant the difference was statistically significant.
