SLC16A7 and cancer: The low glycolytic rates shown by tumors from the lipogenic lineage could anticipate the expression of MCT2 in the plasma membrane in a way to allow cancer cells to obtain energy from oxidative phosphorylation, via uptake of other substrates like lactate itself or pyruvate; however, MCT2 was expressed in the cytoplasm of the majority of tumors, with only one tumor showing plasma membrane expression of this MCT isoform.
