Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P＜0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.

采用5'端缺失策略，结合启动子预测结果，分别构建了8个ACL基因和19个IDH3β基因启动子区重组子，将其转染猪PK15细胞系，并利用荧光素酶双报告基因系统检测了它们的活性，结果表明：在所构建的猪ACL基因5侧翼序列的8个重组子中，除pGL-ACL27和pGL-ACL15外，其它重组子的荧光素酶活性与阴性对照均达到极显著水平(P＜0.01)，表明它们均具有启动子活性，pGL-ACL919活性最强，到pGL-ACL679活性下降了将近3倍，说明从-919bp到-679bp区域可能存在负的调控位点，从pGL-ACL621到pGL-ACL73活性有小幅度下降，到pGL-ACL27活性降到与阴性对照水平无显著差异，表明维持该启动子的基本活性区域位于-73bp到+77bp之间；IDH3β基因启动子活性开始于pGL-IB82，然后虽然有些波动，但是活性一直下降直到-164bp处，之后活性又开始升高，直到-279bp处活性达到最高，这些表明维持该启动子的基本活性区域位于-82bp到+16bp之间，从-82到-279之间的179bp区域具有最高的启动子活性。

In this thesis, we have proposed the algorithms of performing of three improving types, can improve the efficiency of prospecting of the unusual fluctuation database , so the improvement type of a thesis performs algorithms and will not need to rescan the whole database each time when there are newly-increased materials, the majority only needs to scan the newly-increased trade materials, in order to improve the efficiency of prospecting.
