Nei broccoli e in altre verdure simili c'è una proteina che potrebbe entrare a far parte delle armi anticancro: lo svela uno studio del Cancer Center e Cancer Research Institute, presso il Beth Israel Deaconess Medical Center di Boston.
La ricerca mostra che un composto naturale (indol-3-carbinolo) presente nelle crucifere (la famiglia dei broccoli, che comprende anche cavolfiore, cime di rapa, etc) spegne un gene che favorisce i tumori. La scoperta è riportata sulla rivista Science.
In studi su animali predisposti ad ammalarsi di vari tumori, gli esperti hanno scoperto che una molecola nota per sopprimere lo sviluppo di tumori (PTEN, detto oncosoppressore) viene disattivata da WWP-1 e che colpendo WWP-1 con indol-3-carbinolo la funzione di PTEN viene ripristinata e la crescita dei tumori soppressa. Naturalmente si tratta di una ricerca ancora preliminare, ma l'indol-3-carbinolo suggerisce le basi per sviluppare nuove terapie anticancro.
