| Research Abstract |
We have Inolecularly cloned a DNA fragment that contains the promoter sequence of liver/bone/kidney-type alkaline phosphatase gene(Alp). According to the report by Weiss et al., we isolated a DNA fragment of 672 bp that was created by digestion with the restriction enzyme Ava II, and made a chimeric reporter plasmid containing Alp promoter and upstream promoter elements ligated to CAT gene.
More recently, Alp gene was found to have two alternative promoters that make dif-L9erent mRNAs. This raised a urgent problem that we must know which promoter is really active in neutrophils in order to examine the Alp induction in neutrophils.
Since the mRNAs produced by the alternative promoters of Alp differ only in exon I sequence, we made primers specific to each exon I sequence and common exon II sequence and amplified the cDNA produced by MRNA of neutrophils. The results suggested that neutrophils predominantly use bone-type promoter.
