| Research Abstract |
1.We performed the cloning of a new tissue-specific gene in human glands with secondary hyperparathyroidism using Suppression Subtractive Hybridization(SSH) method and determined the each primary structure of the new tissue-specific gene in homo sapiens, Rattus norvegicus and Mus musculus.
2.In situ hybridization, the chief cells in human parathyroid glands with secondary hyperparathyroidism expressed mRNA of the new tissue-specific gene.
3.The strong expression of the new tissue-specific gene can be seen to be expressed in chief cells in human parathyroid glands with secondary hyperparathyroidism.
4.Direct injection of Vitamin D analog into parathyroid gland, were 5/6 nephrectomized and fed a high-phosphorus, upregulated decreased CaR and VDR, and suppressed the proliferation of parathyroid cells and the expression of mRNA of the new tissue-specific gene.
These results suggest that the new tissue-specific gene is giving the proliferation of parathyroid cells with secondary hyperparathyroidism some influences.
