Perinatal exposure to genistein affects the normal development of anxiety and aggressive behaviors and nitric oxide system in CD1 male mice.

Rodriguez-Gomez A.1, Filice F., Gotti S.1, Panzica G.1

Genistein is a phytoestrogen, particularly abundant in soybeans, that is able to bind estrogen receptors exerting both estrogenic and antiestrogenic activities. Genistein is largely present in the human diet even during pregnancy. Embryos and fetuses are therefore, commonly exposed to genistein during the development and after birth. In the present study, we used a murine model as a test end-point to investigate the effects of early exposure to genistein on adult male behavior and related neural circuits.

Exposure of dams to genistein (100?g/g of body weight) daily during late pregnancy and early lactation, produced in male offspring, when adults, significant changes in anxiety behavior and statistically significant variations in the number of neuronal nitric-oxide synthase positive cells in the amygdala. In conclusions, these data indicate that early exposure to phytoestrogens may induce life-long effects on the differentiation of brain structures and behaviors. [read more - PubMed.org]

Torino - 10th International Meeting STEROIDS and NERVOUS SYSTEM

Since 2001, this meeting represented an important event for basic and clinical researchers working on this emerging scientific topic. We will address state-of-the-art approaches in the field of steroids and nervous system, including behavior, epigenetics, genomic and non-genomic actions, the vitamin D, neurodegenerative and psychiatric disorders, and the interference among endocrine disruptors and steroid signaling.

Come nasce una stella: origine e sviluppo degli astrociti, le vere 'star' del cervello

Svelato per la prima volta il processo che genera diversi tipi di astrociti nel cervello. Lo studio del nostro gruppo di ricerca guidato da Annalisa Buffo, pubblicato sulla prestigiosa rivista Plos Biology, conferma il ruolo cruciale degli astrociti nel corretto sviluppo e mantenimento della funzionalità neuronale, e apre nuove strade per comprendere i disturbi del neurosviluppo.
