BCL2 and thyroid gland undifferentiated (anaplastic) carcinoma: Therefore, based on the studies present in the literature on the ability of Trox to act on the apoptotic process in various pathologies, in this work, we demonstrated that Trox at concentrations of 100 and 300 μg/mL increases the expression of the most involved pro-apoptotic proteins, such as Caspase3 and BID, instead reducing the expression of the anti-apoptotic protein bcl-2, more expressed in the treatment-free 8305C control cells, thus inducing apoptosis in anaplastic thyroid carcinoma cells [40].
