Development of experimental models by genetic manipulation in mice has proven to be very useful in determining the significance of particular genes in the development of or susceptibility to hypertension. Advances in molecular genetics, transgenic mouse technology, and physiological measurements in mice provided an opportunity to go a step further and develop models to analyze the physiological significance of specific gene variants potentially causing hypertension. In this report, we describe the development of a human angiotensinogen transgenic mouse model generated by targeting the human angiotensinogen gene upstream of the mouse HPRT locus by homologous recombination. The main benefit of this …

In order to locate the promoter region of the human terminal deoxynucleotidyl transferase gene, serially truncated segments of the 5'-flanking region of the gene were cloned into a chloramphenicol acetyltransferase reporter vector. Transient transfection analyses of the terminal transferase-reporter gene constructs identified the basal promoter region within -34 to +40 base pairs relative to the transcription start site. Three promoter elements were defined in this region. The primary element is within 34 base pairs upstream of the transcription start site. The CAP site is 62 base pairs upstream of the translation start site. The secondary element involves sequences around the …

A nontemplate directed DNA polymerase, terminal deoxynucleotidyl transferase (terminal transferase) is expressed in a tissue-specific and development stage-specific manner. Its enzymatic properties and tissue localization have implicated the protein in development of normal immune function. Significant progress has been made in understanding the enzymology and important domains of this protein. More recently, studies have focused on regulation of the gene that codes for the protein in mice and humans. The murine gene has yielded to these studies more readily than the human gene. A murine basal promoter element has been identified along with several trans-acting protein factors that may regulate …
