The full length cDNA sequence of CBF3 （CRT/DRE-binding factor） was cloned from Vitis amurensis by reverse transcription polymerase chain reaction （RT-PCR） using the primers designed based on CBF genes available in GenBank. Sequence analysis showed that the gene had 854 bp long and its coding sequence contained 720 bp, encoding a protein with 239 amino acids and an AP2 structural domain. The molecular mass of CBF3 was predicted to be 25.9 kDa and its theoretical isoelectric point was 7.02 and aliphatic index was 59.29. The average hydropathicity of the protein was -0.551. The tertiary structures of CBF3 were also analyzed. The prokaryotic expression vector pGEX-4T-CBF3 containing CBF3 gene was constructed and CBF3 fusion protein （52 kDa） was produced in Escherichia coli after induction with 1 mmol L-1 IPTG. Further studies are needed to evaluate its potential application for improving plant resistance to cold and other stress condition such as drought and salinity.

研究乙型肝炎病毒（ＨＢＶ）包膜转基因小鼠肝肿瘤细胞胰岛素样生长因子Ｉ（ＩＧＦ－Ｉ）及其受体（ＩＧＦ－ＩＲ）的表达，观察ＨＢＶ包膜转基因产物在肝细胞中的定位。方法：应用原位杂交技术检测２５只肝肿瘤和１０只正常小鼠肝ＩＧＦ－ＩｍＲＮＡ和ＩＧＦ－ＩＲｍＲＮＡ的表达，用免疫组化法检测ＨＢＶ包膜转基因产物的表达。结果：５２％（１３／２５）的肝腺瘤ＩＧＦ－ＩＲｍＲＮＡ表达增高，肝肿瘤区ＩＧＦ－ＩｍＲＮＡ表达减少。正常肝有ＩＧＦ－ＩｍＲＮＡ表达，但无ＩＧＦ－ＩＲｍＲＮＡ。ＨＢＶ转基因产物主要在肝腺瘤周围的肝细胞浆内表达，在肝腺瘤内的表达显著降低。结论：ＨＢＶ转基因小鼠肝肿瘤出现ＩＧＦ－Ｉ及ＩＧＦ－ＩＲ的异常表达，可能与肝肿瘤的发生、发展过程密切相关。
