The human haptoglobin gene: transcriptional regulation during development and acute phase induction

Open access

Abstract

Haptoglobin is a plasma protein scarcely present in fetal but abundant in adult serum, where it is present at a concentration of approximately 150 mg/100 ml. In this paper we show by run-on experiments that the haptoglobin (Hp) gene is actively transcribed in adult but not in fetal liver nuclei. Studies with established cell lines indicate that the Hp gene is expressed in the hepatoma cells HepG2 but not in the hepatoma cell line Hep3B nor in HeLa cells. Plasmids carrying various segments of the 5' flanking region of the Hp gene fused to the chloramphenicol acetyl transferase (CAT) gene direct CAT transcription when introduced into HepG2 but are inactive in Hep3B and in HeLa cells, thus behaving like the resident chromosomal Hp gene. Deletion analysis defines a region, upstream to the transcription initiation site, essential for cell-specific expression. The Hp gene is induced in Hep3B cells by treatment with supernatant from LPS-stimulated monocytes (SMS), in a manner mimicking the acute phase reaction. We characterize the DNA segment necessary and sufficient for cell-specific expression of the Hp-CAT constructions in HepG2 and show that the same segment is also sufficient for acute phase induction in Hep3B.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
