Abstract
Turpentine-induced acute-phase (AP) response in rats is followed by transcriptional activation of the haptoglobin (Hp) gene in liver. Analysing the promoter sequence of the rat Hp gene we postulated an involvement of Signal Transducer and Activator of Transcription 3 (STAT3) in the regulation of this process. Results obtained by using a combination of Western immunoblot and DNA-binding assays revealed AP-induced binding of constitutive 86kD- and inducible 91kD-STAT3 isoforms to the rat Hp gene inducible promoter element. On the basis of these data we assumed that AP-related interactions of these two STAT3 isoforms correlates with an activated transcriptional status of the rat Hp gene.
