I am working on computational method to find out target mRNA for some selected miRNA. In NCBI I found expression matrix to do my job. Finally using MiRTarBase to validate my computational result.
In MiRTarBase there is miRNA like, hsa-miR-200a and its target gene like VIM, CHD9 etc.
But, in the expression data from NCBI, the miRNA are represented by an ID like, 3980, 9938 etc.
The mRNA from NCBI are represented by ID like, AFFX-BioB-M_at, AFFX-BioB-M-3_at etc.
I can see that the ID reference from the two sources for miRNA and mRNA are different. How can I match an ID from NCBI to an ID with MiRTarBase / TarBase ? If I have any misconception please clarify ...
