摘 要
通过基因芯片技术,利用
Roche-NimbleGen
公司制作的大鼠
12×135K
全基因组表达谱芯片,对日龄为
6 d
10 d
的大鼠睾丸组织进行全基因组表达差异分析。结果显示:具有
2
倍以上的差异表达基因有
4 298
个,其中表达上调的基因共
1 878
个,表达下调的基因共
2 420
。这些差异表达的基因中有
3 154
个基因具有基因本体注释,参与了
154
个生物学通路。
进一步分析表明具有
8
倍以上差异表达的基因有
13
个,这些基因参与了生物学过程,细胞组分,分子功能等基因本体分类,
进一步选择
3
个差异表达的基因,
LOC686076
Cxcl6
Trib3
,做了实时定量
RT-PCR
检测。其结果趋势与芯片数据一致。
因此,我们初步认为精原干细胞的发生与增殖在大鼠早期的发育过程中已经有大量的基因参与,是一个多基因协调表达的过程。

Abstract
In this research, differential analysis of genome-wide expression of the rat testis tissues in the age of 6 and 10 days was
conducted by gene chip technology based on the 12×135K genome-wide EST microarray of rat produced by Roche-NimbleGen. The
results showed that there were 4 298 genes with 2
-
fold or more differentially expressed in the rat testis tissues between the ages of 6
and 10 days, thereinto, 1 878 genes were up- regulated expression and 2 420 genes were down-regulated expression. 3 154 genes of
these differentially expressed genes have been annotated with gene ontology, participating in the 154 biological pathways. Further
analysis showed that there were 13 genes with more than 8 fold differential expression, those genes involved in Gene Ontology
categories, such as biological processes, cellular components and molecular functions and so on. Three differentially expressed genes,
LOC686076
,
Cxcl6
and
Trib3
, were chosen to detect by real-time quantitative RT-PCR, the results exhibited a tread toward the
microarray data. Therefore, we preliminary thought that a large number of genes should be involved in the occurrence and
proliferation of spermatogonial stem cell in early stages of growth and development of the rat,
it might be
a
synchronizing
process of
multi-
gene
expression.
