Potential prognostic value of miR-132 and miR-212 expression in mCRPC patients

To the Editor, we have been very pleased to read the interesting work proposed by Salemi et al. regarding the expression of specific fragments of microRNA (miRNA), particularly miR-132 and miR-212, as potential key regulators in prostate cancer (PCa). As outlined by the Authors, the altered expression of miRNAs in cancer pathogenesis represents a well-consolidated knowledge in the current literature. More specifically, both miR-212 and miR-132 regulate subsets of genes involved in tumor progression in several tumor cell types as PCa, proving a central role in tumorigenesis, cell adhesion, and angiogenesis. In addition, a strong association between miR-132 expression and high Gleason score PCa has been lately depicted [...].
