A recent study have demonstrated that Dihydrotanshinone I, a tanshinone extracted from Salvia miltiorrhiza Bunge, can induce a decrement of NF-κB activity in anaplastic thyroid cancer paclitaxel-resistant cells SW1736-PTX and 8505C-PTX, resulting in decreased viability and clonogenic ability of the resistant cells [33]. This evidence concerns the gene NFKB1 and thyroid gland undifferentiated (anaplastic) carcinoma.
