Core Tip

Core tip: This paper describes, for the first time, the role of monocarboxylate transporters in hepatic carcinoma. The characterization of monocarboxylate transporter activity in acidic metabolism of primary and metastatic hepatocellular carcinoma microenvironment was studied in necropsy material and allowed us to precisely evaluate the impact of the more acidic microenvironment that is potentially maintained by monocarboxylate transporter 4 and glucose transporter-1 during hepatocellular carcinoma progression.
