Preclinical studies in a mouse model of ASPS have demonstrated the upregulation of monocarboxylate transporter 1 (SLC16A1) and basigin (BSG), both associated with the importation of lactate into the cells, and the downregulation of monocarboxylate transporter 4 (SLC16A3), a gene associated with lactate export [115]. The gene discussed is SLC16A1; the disease is alveolar soft part sarcoma.
