Notably, recent immunohistochemical analysis of MCT1, MCT2, and MCT4 on 73 primary HCCs revealed that the plasma membrane expression of MCT2 was detected in only 12.2% of tumor samples, while MCT1 and MCT4 were detected in 54.8% and 38.2% of tumor samples, respectively [64]. Here, SLC16A7 is linked to neoplasm.
