In our experimental procedures, we described in great detail which company’s RNA products were used for microRNA overexpression, the transfection reagents used, the system used to run our real-time PCR, and the list of gene primer sequences used to perform PCR or the catalog number of the microRNA assay. We followed recommendations of the manufacturer where indicated. We searched PubMed, and as of August 15, 2013, many of the microRNAs we mentioned as examples of putative, novel mesothelioma-associated microRNAs remained consistent. In the Discussion section, we limited the context to prior microRNA profiling studies, not an encyclopedic review of every microRNA that has heretofore been mentioned with mesothelioma. The Kubo et al2 article is not a microarray profiling study, but details the methylation status of miR-34b and its functional implication.
