摘要:

目的 通過挖掘乳腺癌疾病力學(xué)-藥物靶點(diǎn),將力學(xué)與藥物相結(jié)合,為乳腺癌新藥的開發(fā)以及老藥新用提供重要參考。方法 基于乳腺癌多重表達(dá)譜數(shù)據(jù)及GO數(shù)據(jù)庫注釋文件,應(yīng)用差異表達(dá)分析及富集分析等生物信息學(xué)方法挖掘與乳腺癌疾病力學(xué)-藥物相關(guān)的作用靶點(diǎn),并基于藥物靶點(diǎn)數(shù)據(jù)庫構(gòu)建包含GO功能-基因-藥物的三維網(wǎng)絡(luò)圖。結(jié)果 通過整合數(shù)據(jù)識(shí)別出乳腺癌疾病中參與到力學(xué)-藥學(xué)作用機(jī)制中的靶點(diǎn)87個(gè),其中12個(gè)被證實(shí)為乳腺癌或癌癥藥物靶點(diǎn)并且發(fā)揮了力學(xué)相關(guān)功能,其余靶點(diǎn)可作為潛在乳腺癌藥物靶點(diǎn)。結(jié)論 通過數(shù)據(jù)挖掘找出87個(gè)參與到乳腺癌疾病力學(xué)-藥學(xué)作用中的靶點(diǎn),揭示了乳腺癌疾病中力學(xué)-藥物作用的分子機(jī)制,為疾病藥物治療提供了指引。

Objective The combination of mechanics and drugs through the mining of mechanics-drug targets for breast cancer provide an important reference for the development of new drugs for breast cancer and repurposing old drugs.Methods Based on the multiple expression data of breast cancer and the annotation data in GO database,bioinformatics methods such as differential expression analysis and enrichment analysis were used to explore the targets involved in the mechanics-drug interaction in breast cancer,and constructed a three-dimensional network of GO function-gene-drugs based on the drug target databases.Results Eighty-seven targets involved in the interaction between mechanics and pharmacology in breast cancer were identified through integrating the data,of which 12 targets were confirmed to be breast cancer or cancer drug targets and played a mechanical role,and the other genes could be used as potential targets for breast cancer drugs and served as reference for related studies.Conclusions Through data mining,we identified 87 targets involved in the mechanical-pharmaceutical interaction in breast cancer,and revealed the molecular mechanism of mechanical-pharmaceutical interaction in breast cancer,which provided guidelines for drug therapy.
