By designing four primers for an overlapping PCR, we created a fusion gene Ddlcat encoding human TNF receptor I death domain and
chloramphenicol acetyltransferase
(
CAT
). By DNA sequencing, the whole sequence of the fusion gene is confirmed to be correct. Two hours after induction with IPTG, we could see a 39 kD extra protein band on SDS-PAGE pattern. We proved that this 39 kD protein band is DdLcat protein by Western blotting. Then we purified this protein to the purity of 95% through Q-Sepharose chromatography.

The work was aimed to identify the estrogen responsive element in the human angiotensinogen gene. The nucleotide sequence between the transcription initiation site and TATA box in angiotensinogen gene promoter was found to be strongly homologous with the consensus estrogen responsive element. This sequence was confirmed as the estrogen responsive element (HAG ERE) by electrophoretic mobility shift assay. The recombinant expression vectors were constructed in which
chloramphenicol acetyltransferase
(
CAT
) reporter gene was driven by angiotensinogen core promoter with HAG ERE of by TK core promoter with multiplied HAG ERE, and were used in cotransfection with the human estrogen receptor expression vector into HepG(2) cells;
CAT
assays showed an increase of the
CAT
activity on 17beta-estradiol treatment in those transfectants. These results suggest that the human angiotensinogen gene is transcriptionally up-regulated by estrogen through the estrogen responsive element near TATA box of the promoter.
