Introduction
Our research is focused on the identification of microRNAs, lncRNAs, circRNAs, and proteins deregulated in breast, lung, ovarian and colorectal cancers using omics approaches. We are interested in the identification of novel therapeutic targets, and elucidation of mechanisms of tumorigenesis. We are also working on Nutrigenomics evaluating the chemopreventive role and impact in methylome/microRNOme of dietary polyphenols in cancer . Also we are working on 3D genome organization in 3D cultures.

Deregulated expression of microRNAs has been associated with angiogenesis. Studying the miRNome of locally advanced breast tumors we unsuspectedly found a dramatically repression of miR-204, a small non-coding RNA with no previous involvement in tumor angiogenesis. Downregulation of miR-204 was confirmed in an independent cohort of patients and bre...
