[Method] The total RNA was extracted by using Trizol from the liver of Hubei white swine and used as template to amplify IGF-1 gene cDNA by RT-PCR. The cDNA product was cloned into pCRII vector, screened with blue-white colonies, digested with double enzymes and sequenced. [Result] The sequencing result indicated that the IGF-1 gene consisted of 607 nucleotides, containing 5'-untranslated region at nucleotides 1-145, a complete ORF at nucleotides 146-538 encoding 130 amino acids, and 3'-untranslated region at nucleotides 539-607. It shared 100% homology with the porcine IGF-1 gene reported by Muller et al. [Conclusion] The successful cloning and sequencing of the Hubei white swine IGF-1 gene confirmed that IGF-I gene was highly conserved, which provided technical basis for the use of transgenic technology for breeding of Hubei white swine.展开更多

文摘[Objective] The study aimed at cloning and analyzing the insulin-like growth factor-1 (IGF-1) gene from liver of Hubei white swine. [Method] The total RNA was extracted by using Trizol from the liver of Hubei white swine and used as template to amplify IGF-1 gene cDNA by RT-PCR. The cDNA product was cloned into pCRII vector, screened with blue-white colonies, digested with double enzymes and sequenced. [Result] The sequencing result indicated that the IGF-1 gene consisted of 607 nucleotides, containing 5'-untranslated region at nucleotides 1-145, a complete ORF at nucleotides 146-538 encoding 130 amino acids, and 3'-untranslated region at nucleotides 539-607. It shared 100% homology with the porcine IGF-1 gene reported by Muller et al. [Conclusion] The successful cloning and sequencing of the Hubei white swine IGF-1 gene confirmed that IGF-I gene was highly conserved, which provided technical basis for the use of transgenic technology for breeding of Hubei white swine.

文摘Titanite(CaTi2SiO5) is an important accessory mineral not only in magmatic and metamorphic rocks,but also commonly in hydrothermal mineral deposits. It incorporates appreciable amounts(usually 10×10-6 s to 100×10-6 s) of U and Th into its structure and has a closure temperature of Pb diffusion higher than 660~700 ℃(Scott and St-Onge,1995) ,making it an ideal U-Th-Pb geochronometer. The Daye metallogenic district is located in the west of the giant Middle-Lower Yangtze River(MLYR) Cu-Fe-Au province,eastern China and is well endowed with Fe,Cu,and polymetallic skarn deposits.
