Immunoblot analysis showed that alpha-class glutathione S-transferase (GST), which is one of the major forms in adult human liver, was expressed in human fetal liver. Mu-class GST was also expressed in fetal liver. The majority of mu-class GST expressed in adult liver consisted of a subunit with a molecular weight of 27 kDa on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), whereas two subunits of 27 and 26 kDa were detected in fetal liver as proteins immunochemically related to mu-class GST. On reverse-phase HPLC, these two subunits cross-reactive with antibodies to rat GST 3-3 in fetal liver were indistinguishable from each other in their retention time; though, they could be separated by chromatofocusing analysis. The molecular weights of GSTs immunochemically related to rat GST 3-3, eluted at pH 7.1, 6.4, and 5.7, were 27, 27 and 26, and 26 kDa, respectively. In addition, the N-terminal amino acid sequence of these subunits suggested that GSTs related to rat GST 3-3 expressed in fetal liver may be homodimeric and heterodimeric proteins. As expected, pi-class GST was found to be a major form of GST in fetal liver but not in adult liver. In contrast, the GST immunochemically related to rat GST Yrs-Yrs, which is classified as theta-class GST, was detected in adult liver but not in fetal liver. These results indicate that several isoenzymes of GST are expressed in human fetal liver, but they are not the same as those in adult liver.
