Strigolactones have been shown to anti-proliferative and pro-apoptotic effects in cell cultures of breast and prostate origin, partially by down-regulation of cyclin B1 and induction of cell cycle arrest. In this study the investigators intend to take biopsies from benign colonic polyps and cancer tissue, culture intestinal explants and generate immortalized primary cells as a platform to assess the effect of this plant hormone on cell viability, cell mobility, apoptosis and cytoskeleton modifications.
