text: This process was reduced by a protonophore, carbonylcyanide p-trifluoromethoxyphenylhydrazone, and a typical monocarboxylate transporter (<< MCT >>) inhibitor, [[ alpha-cyano-4-hydroxycinnamic acid ]], suggesting that nicotinate uptake by rat astrocytes is mediated by H(+)-coupled monocarboxylate transport system.
