ABSTRACT
<p><b>OBJECTIVE</b>To clone a novel gene relative to blood glucose regulation.</p><p><b>METHODS</b>Rat modes of autonomous regulation of blood glucose was made by intra jugular vein to right atrium injection of high concentration of glucose solution, and the control rats were injected with 0.9%NaCl both before skeletal muscles were separated for gene analysis. The differentially expressed fragments were identified by differential display technology (DDRT-PCR). After slot blot and Northern blot analysis, the artificial positive fragments were excluded and the true EST (expression sequence tag) differentially expressed was obtained. These positive EST were used as probes to screen cDNA library of rat skeletal muscle.</p><p><b>RESULTS</b>A novel full-length cDNA, named as Fang-2 was obtained. GenBank Accession No. was AF399874. Fang-2 was found rat homologue of human troponin T by blast software (NCBI). It shared 78% identical nucleotides, which showed the family proteins were conservative. After high concentration of glucose stimulation of rats, the expression of Fang-2 was down-regulated.</p><p><b>CONCLUSIONS</b>A novel gene relative to blood glucose regulation was cloned from rat skeletal muscle. The gene can regulate blood glucose level by effect certain mechanisms unknown yet with down-regulation expression.</p>
