Nowadays, as more and more associations between microRNAs (miRNAs) and diseases
have been discovered, miRNA has gradually become a hot topic in the biological
field. Because of the high consumption of time and money on carrying out
biological experiments, computational method which can help scientists choose the
most likely associations between miRNAs and diseases for further experimental
studies is desperately needed. In this study, we proposed a method of Graph
Regression for MiRNA-Disease Association prediction (GRMDA) which combines known
miRNA-disease associations, miRNA functional similarity, disease semantic
similarity, and Gaussian interaction profile kernel similarity. We used Gaussian
interaction profile kernel similarity to supplement the shortage of miRNA
functional similarity and disease semantic similarity. Furthermore, the graph
regression was synchronously performed in three latent spaces, including
association space, miRNA similarity space, and disease similarity space, by using
two matrix factorization approaches called Singular Value Decomposition and
Partial Least-Squares to extract important related attributes and filter the
noise. In the leave-one-out cross validation and five-fold cross validation,
GRMDA obtained the AUCs of 0.8272 and 0.8080 ± 0.0024, respectively. Thus, its
performance is better than some previous models. In the case study of Lymphoma
using the recorded miRNA-disease associations in HMDD V2.0 database, 88% of top
50 predicted miRNAs were verified by experimental literatures. In order to test
the performance of GRMDA on new diseases with no known related miRNAs, we took
Breast Neoplasms as an example by regarding all the known related miRNAs as
unknown ones. We found that 100% of top 50 predicted miRNAs were verified.
Moreover, 84% of top 50 predicted miRNAs in case study for Esophageal Neoplasms
based on HMDD V1.0 were verified to have known associations. In conclusion, GRMDA
is an effective and practical method for miRNA-disease association prediction.
