Background: Radioiodine (131I) therapy is performed in patients with differentiated thyroid cancer (DTC), either for thyroid remnant ablation or treating distant metastasis. Although 131I therapy is generally considered safe, a genotoxic damage has been demonstrated both in vivo and in vitro.Aim: To evaluate the possible effect of Ginkgo biloba extract (EGb 761) supplementation on the time-course (up to 1...

Extracellular nucleotides, via specific plasma membrane receptors (P2Rs) of the X and Y subtype, modulate several cell functions, including cell-to-cell cross talk. We have previously demonstrated the expression of several functional P2XRs subtypes, including P2X7, in primary human thyrocytes. P2X7 is the main player in inflammation and immunomodulation; a strong expression of this receptor has been shown in several human solid tumors. Polymorphisms of the gene enco...

In March 2020, the infection due to COVID-19 spread as a pandemic emergence showing a mutable phenotype ranging from asymptomatic to lethal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Among multiple biological and environmental investigated factors, vitamin D status was proposed as a credible candidate, since hypovitaminosis D could be identified as a modifiable risk factor and a potential tool in SARS-CoV-2 ...

Extracellular ATP modulates several biological processes via activation of plasma membrane receptors (P2Rs) in normal human thyrocytes (NT). We characterized P2Rs expression and function in two thyroid cancer cell lines: FB1 (anaplastic cancer) and FB2 [papillary cancer (PTC)]. P2Rs expression was evaluated by RT-PCR and WB, intracellular Ca2+changes by fluorimetric technique (Fura2-AM), IL-6 release by ELISA, intracellular [i(ATP)] and extracellular ATP [...
