  Recently,long non-coding RNA is thought to be contained in human genome as important regulatory transcripts in which we can identify far more previously unappreciated.They serve as scaffolds associating with a protein and genome DNA.In our recent study,we identified non-overlapping signatures of a small number of lncRNAs that are aberrantly expressed in human HBV-related HCC compared to paired pertitumoral tissues and among which lncRNA H19 was found to speculate a potential role in HCC progression.Evidence from past studies has shown a strong association between H19 and carcinogenesis in several types of cancer including liver.The expression of H19 usually changes from monoallelic to biallelic in HCC through aberrant DNA methylation.

近年来,未成熟睾丸组织异种移植技术不仅成为揭示睾丸生理学和雄性生殖细胞发育的有用工具,也为遗传学家研究转基因动物、突变或克隆动物提供有了利条件,同时也为雄性生殖系的保存提供了新思路,从而可为有价值的畜牧和珍惜/濒危物种保护提供有价值的方案。本课题组以新生小鼠睾丸组织为供体,免疫缺陷小鼠为受体进行组织移植;将1~2 d龄昆明小鼠睾丸组织植入去势裸鼠背部,于移植后40~110 d取出移植物,观察生精小
