Research topics

Two are the main topics of our research activity:
1- to study steroids and their receptor in pathophysiological conditions in human and in animal models: we first studied the control of dimorphic brain differentiation during embryogenesis; then, our interests moved to the disruptive effects of some environmental pollutants as polychlorinated biphenyls (PCB) and, more recently, bisphenol A (BPA) on brain differentiation and functions.
2- to study the mechanisms by which a human preparation from whole blood, the platelet rich plasma (PRP), and external stimuli as electromagnetic fields (EMF) are involved in the pro-mitotic and pro-migration effects in tissues and cells involved in regenerative/repair processes.
To this purpose, our research activity deals with:

  1. the evaluation of the BPA effects, mechanism of action and epigenetic effects on organs and tissues involved in the control of reproduction during pregnancy (PRIN 2015 - PI Prof.ssa Ricci, Siena).
  2. To evaluate the use of platelet gels and electromagnetic fields, alone or in combination, to improve the wound healing process in tissues altered by low gravity conditions as it happens on the ISS - International Space Station (project granted by ASI – SUTURE 2018).



Currently used methods of cellular and molecular biology in the lab:

-       Cell cultures, transient transfections, proliferation assays (MTT, cell count), transcriptional activity by luciferase assay, immunofluorescence, migration assays by Boyden Chamber or scratch assay, immunoassays.

-       Bacterial transformation and amplification, qualitative RT-PCR, Real time PCR (TaQMan and SyBR Green), fluorescence Western blotting, global DNA methylation analysis by Elisa kit, Methylation specific PCR.

-       we also use the following software for primer design (Primer3 o Primer blast), for statistics (SPSS) and for gene sequences analysis (Genomatix).
