Increasing evidences have indicated that microRNAs (miRNAs) are functionally associated with the development and progression of various complex human diseases. However, the roles of miRNAs in multiple biological processes or various diseases and their underlying molecular mechanisms still have not been fully understood yet. Predicting potential miRNA-disease associations by integrating various heterogeneous biological datasets is of great significance to the biomedical research. Computational methods could obtain potential miRNA-disease associations in a short time, which significantly reduce the experimental time and cost. Considering the limitations in previous computational methods, we developed the model of Within and Between Score for MiRNA-Disease Association prediction (WBSMDA) to predict potential miRNAs associated with various complex diseases. WBSMDA could be applied to the diseases without any known related miRNAs. The AUC of 0.8031 based on Leave-one-out cross validation has demonstrated its reliable performance. WBSMDA was further applied to Colon Neoplasms, Prostate Neoplasms, and Lymphoma for the identification of their potential related miRNAs. As a result, 90%, 84%, and 80% of predicted miRNA-disease pairs in the top 50 prediction list for these three diseases have been confirmed by recent experimental literatures, respectively. It is anticipated that WBSMDA would be a useful resource for potential miRNA-disease association identification.
越来越多的证据表明,微小RNA(miRNA)在各种复杂人类疾病的发生和发展过程中发挥着功能作用。然而,miRNA在多种生物学过程或各种疾病中的作用及其潜在的分子机制仍未得到充分理解。通过整合各种异质生物数据集来预测潜在的miRNA-疾病关联对生物医学研究具有重要意义。计算方法能够在短时间内获得潜在的miRNA-疾病关联,这显著减少了实验时间和成本。考虑到以往计算方法的局限性,我们开发了用于miRNA-疾病关联预测的内外评分模型(WBSMDA),以预测与各种复杂疾病相关的潜在miRNA。WBSMDA可应用于没有任何已知相关miRNA的疾病。基于留一法交叉验证的0.8031的曲线下面积(AUC)证明了其可靠的性能。WBSMDA进一步应用于结肠癌、前列腺癌和淋巴瘤,以鉴定其潜在的相关miRNA。结果,这三种疾病前50名预测列表中90%、84%和80%的预测miRNA-疾病对已被最近的实验文献证实。预计WBSMDA将成为识别潜在miRNA-疾病关联的有用资源。
