In their manuscript titled 'Multi-platform miRNA profiling of FFPE samples from Hepatoblastoma patients,' Leichter et al. describe tumor microRNA expression profiles of 13 cases of hepatoblastoma. The microRNA data was obtained using three different technologies. Besides hepatoblastoma researchers, findings of this study should be of broad interest to those investigating microRNAs/small RNAs because of the nature of specimens (formalin-fixed tissues, the most commonly available type of archived clinical material) and because of the study's focus on comparison of the three different microRNA quantification technologies.

However, in my opinion, most of the information provided in this manuscript, has already been published recently in Scientific Reports (5, article 10438, June 2015). I therefore do not see a reason to publish this manuscript.
