Abstract

The onset of thyroid gland nodules (TN) is determined by loss of homeostasis regulation by interactionof endogenous/genetic and environmental factors. The nature of the oxidative processes that lead tophysiologic synthesis of thyroid hormones together with environmental factors may be the root causesof thyroid nodular transformation due to an increase in DNA damages. A link between EGF and DNAdamage repair signalling has been documented in cancer, but their cross-regulation is poorly understoodin TN. In order to define the role of Base Excision Repair (BER) and ErbB signaling in TN, we analysedeuthyroid goitres tissues that are not theoretically affect by any hormonal dysfunction.
