Identification of a gene associated with astragalus and angelica's renal protective effects by silver staining mRNA differential display.
OBJECTIVE
To identify genes associated with the chronic progression of renal disease and a stragalus and angelica (A&A)'s renal protective effects.


METHODS
The technique of silver staining mRNA differential display (DD) was used to investigate changes of gene expression in normal, sclerotic and A&A treated sclerotic kidneys. We isolated genes differentially expressed during the progression of renal disease which could be normalized by A&A.


RESULTS
Several genes related to A&A's protective effects were isolated and one of them was confirmed by Northern blot.


CONCLUSIONS
Silver staining mRNA differential display is a simple and effective technique for isolating differentially expressed genes. The isolated new gene may be related to the progression of chronic renal disease and contribute to A&A's protective effects.
