The effects of acute-phase inducers and dimethyl sulphoxide (Me2SO) on delta-aminolaevulinate (ALA) synthase in HepG2 cells were examined. Treatment of cells with Me2SO resulted in a significant increase in ALA synthase activity. Interleukin-6 increased ALA synthase activity only slightly, but it substantially potentiated the induction of ALA synthase by Me2SO. These data suggest that ALA synthase activity in liver is altered during acute-phase reactions.
