服務(wù)內(nèi)容:
與常規(guī)的從lncRNA出發(fā)預(yù)測靶基因不同,反向long noncodingRNA(lncRNA)靶基因預(yù)測是從感興趣的已知基因開始(例如p53,COX-2等與腫瘤等密切相關(guān)的基因,這些基因可以來自芯片分析結(jié)果、NLP結(jié)果或客戶給定的任何基因列表),利用我們的longnoncoding RNA(lncRNA)數(shù)據(jù)庫和靶基因預(yù)測軟件pipeline,找到潛在的調(diào)節(jié)這些基因的lncRNA。
研究方法:
我們的服務(wù)提供:
1.獲取感興趣的基因集合
這些基因可以來自芯片分析結(jié)果、NLP結(jié)果或客戶給定的任何基因列表。如p53,COX-2。
2.建立lncRNA數(shù)據(jù)庫
我們通過整合已知所有l(wèi)ncRNA數(shù)據(jù)庫,形成一個全面的包含所有l(wèi)ncRNA序列的數(shù)據(jù)庫
3.細胞組織特異高表達lncRNA的鑒定(可選)
根據(jù)客戶提供的細胞組織信息,我們搜索已有的tiling芯片以及新一代測序得到的轉(zhuǎn)錄組信息,從全基因組已知lncRNA的中鑒定高表達的lncRNA。
4.cis靶基因預(yù)測
Cis作用[5]是lncRNA的一種靶基因作用方式。我們利用基因組注釋和基因組瀏覽器鑒定lncRNA的可能的靶基因。一般在啟動子區(qū)域同向轉(zhuǎn)錄的靶基因一般是促進表達作用,反向為抑制。而在3’-UTR區(qū)域時,部分情況下反向也為促進表達,見[14]。
5.trans靶基因預(yù)測
trans作用是lncRNA的另一種靶基因作用方式。我們利用RNAplex(
http://www.tbi.univie.ac.at/~htafer/)等鑒定lncRNA的可能的靶基因,一個例子請見[15]。
綜上,一個可能分析流程如下:
