Research Interests<\/h1>\n

The activity of our laboratory is focused on the elucidation of the molecular mechanisms driving the transcritpional control played by hormones on target genes, mainly upon the identification of the specific epigenetic marks that label the process.<\/p>\n

In particular, we have studied the modifications at the N-terminal tails of nucleosomal histones induced by chromatin recruitment of the estrogen receptor (ER), the nuclear receptor that mediates the estrogen action on responsive cells. On this regard, we have found that estrogen-induced transcription id governed by ER-triggered demethylation of lysine 9 in histone H3 realized by the lysine-specific demethylase 1 (LSD1), with consequent production of reactive oxygen species (ROS) and oxidation of nearby guanines (8-oxo-Gs) that result into formation of single and double-stranded breaks, allowing the establishment of contacts between sites distant on linear DNA. We have also evidenced that the histone-tail modification cited above represents a pre-requisite for addition of the phosphoryl mark to serine 10 that is known to accompany active gene expression.<\/p>\n

In addition, we have pictured a new role to this latter epigenetic mark that in fact, by ensuring production of ROS to be cyclical, preserves DNA wholeness during active transcription. On this basis, we have highlighted a novel use of estrogens that, in combination with inhibition of serine 10 phosphorylation, could be used in new trials for treatment of human hormone-responsive cancers, as the hormone, under these conditions, induces selective apoptosis of target cells.<\/p>\n
