3-Iodothyronamine (T1AM) is a hormone like molecule structurally similar to TH, that has been reported to modulate energy metabolism by favoring lipid over glucose catabolism. To better understand the role played by T1AM on the regulation of lipid metabolism, in the present study we administered spontaneously obese mice with T1AM at two different dosages (10 and 25 mg/kg per day) for 7 days and the effects on body weight (BW) and lipid profiles were examined. In addition a flu...

Atrial fibrillation (AF) and, in general, cardiac arrhythmias are among the most frequent complications during clinical thyrotoxicosis. However to-day the most frequent conditions of hyperthyroidism are subclinical and more subtle is the relationship between this last condition and cardiac arrhythmias.In order to evaluate this topic, we considered two groups: A) patients admitted into the hospital for AF; B) patients affected by subclinical hyperthyroidi...

Endogenous TH metabolite 3-iodothyronamine (T1AM) and recently developed thyronamine-like synthetic analogues SG1 and SG2 have emerged as neuroprotective agents. Autophagy has proved to be an effective therapeutic approach for neurodegenerative diseases. Therefore we investigated whether these compounds can induce autophagy in human glioblastoma cells (U-87MG).Cultured U-87MG cells were initially treated with 1 μM T1AM, SG-1, SG-2 or vehicle for 30&...

Introduction: BC patients have a high prevalence of anti-TPO-autoantibodies (TPOAb), which seem to be protective in BC patients. We hypothesized the presence of T-lymphocytes citotoxicity against a common antigen between thyroid and BC cells.Aim: To evaluate the possible expression of TPO gene in BC.Materials: Frozen tissue specimens: 8 BC, 5 peri-tumoral breast tissues (PT), 3 pancreatic adenocarcinoma (P), 2 kidney cancers (K) an...
