Just out is the article about a method for analysis of multiple molecular profiles at the same time (BMC Bioinformatics, 2016). It essentially extends the method first proposed by Menezes et al. (BMC Bioinformatics, 2009) for multiple covariate sets. In the same article you can find a comparison of gene expression-regulating mechanisms between colon and breast cancer, found by the method. Results for the whole genome can be found in the Additional Files.
