    摘要: Disclosed is a transformed yeast cell containing a first heterologous DNA sequence which codes for a mammalian G protein coupled receptor and a second heterologous DNA sequence which codes for a mammalian G protein &agr; subunit (mammalian G&agr;). The first and second heterologous DNA sequences are capable of expression in the cell, but the cell is incapable of expressing an endogenous G protein &agr;-subunit (yeast G&agr;) The cells are useful for screening compounds which affect the rate of dissociation of G&agr; from G&bgr;&ggr; in a cell. Also disclosed is a novel DNA expression vector useful for making cells as described above. The vector contains a first segment comprising at least a fragment of the extreme amino-terminal coding sequence of a yeast G protein coupled receptor. A second segment is positioned downstream from the first segment (and in correct reading frame therewith), with the second segment comprising a DNA sequence encoding a heterologous G protein coupled receptor.

    摘要: The present invention discloses the use of extracts from the plants of the genus Amaranthus, such as the extracts from Amaranthus mangostanus L. and Amaranthus tricolor L., in lowering the blood glucose level. The present invention further provides anti-diabetes compositions or blood glucose-regulating dietary supplements, which contain the Amaranthus plant extracts as active agent.

    摘要: Disclosed is a transformed yeast cell containing a first heterologous DNA sequence which codes for a mammalian G protein-coupled receptor and a second heterologous DNA sequence which codes for a mammalian G protein α subunit (mammalian Gα). The first and second heterologous DNA sequences are capable of expression in the cell, but the cell is incapable of expressing an endogenous G protein α-subunit (yeast Gα). The cells are useful for screening compounds which affect the rate of dissociation of Gα from Gβγ in a cell. Also disclosed is a novel DNA expression vector useful for making cells as described above. The vector contains a first segment comprising at least a fragment of the extreme amino-terminal coding sequence of a yeast G protein-coupled receptor. A second segment is positioned downstream from the first segment (and in correct reading frame therewith), with the second segment comprising a DNA sequence encoding a heterologous G protein-coupled receptor.
