CDH1 and thyroid gland undifferentiated (anaplastic) carcinoma: This notion is further supported by the redifferentiation tendency of resveratrol-treated THJ-11T in terms of increased Tg and E-cadherin production and, especially, the appearance of membranous E-cadherin localization that, as shown in the current study, are extremely low and even absent in undifferentiated and, especially, anaplastic thyroid cancers [26,27,28,29].
