New epigenetic and functional features in pheochromocytoma

Manso Jacopo , Bertazza Loris , Barollo Susi , Censi Simona , Carducci Sofia , Mian Caterina

Background: Pheochromocytoma (Pheo) is a tumor deriving from chromaffin cells. It can be studied using 18F-dihydroxyphenylalanine (DOPA) - positron emission tomography (PET) due to its overexpression of L-type amino acid transporters (LAT1 and LAT2). The oncogenic pathways involved are still poorly understood. This study examined the relationship between 18F-DOPA-PET uptake and LAT1 expression, and explored the role of miR-375 and putative target genes.</...

Role of the calcium-calmodulin dependent kinase 2 in medullary thyroid carcinoma

Russo Eleonora , Salzano Marcella , De Falco Valentina , Santoro Massimo , Mian Caterina , Barollo Susi , Vitale Mario

Recent studies demonstrated that the calcium/calmodulin dependent kinase 2 (CaMKII) is involved in the regulation of proliferation and survival of epithelial cells, were it phosphorylates RAF-1 and modulates MAPK pathway. A endogenous CaMKII inhibitor (hCaKIINα) is expressed in some cell types. It is down-expressed in colon and in ovarian cancer where it inversely correlates with the disease extension.Aim of our study is to determine the possible ro...

The hobnail variant of papillary thyroid carcinoma: clinical/molecular characteristics of a large monocentric series and comparison with conventional histotypes

Censi Simona , Manso Jacopo , Paganin Francesco , Vianello Federica , Galuppini Francesca , Pennelli Gianmaria , Iacobone Maurizio , Bertazza Loris , Barollo Susi , Mian Caterina

Background: Hobnail variant of papillary thyroid carcinoma (HPTC) has been recently identified. Given the rarity of the variant its characteristics have been studied only in little series, limiting the quality of the data available for its better management. The aims of our retrospective study were 1) to define the clinical and molecular characteristics of a series of HPTC in a monocentric and relatively large series; 2) to define the clinical and molecular characteristics abl...

Therapeutic plasma exchange in amiodarone induced thyrotoxicosis: a case report

Clausi Cristina , Manso Jacopo , Graziani Andrea , Censi Simona , Carducci Sofia , Zhu Yi Hang , Piva Ilaria , Mian Caterina

A 52-year man came to Emergency Department with Atrial Fibrillation with rapid ventricular response due to amiodarone induced thyrotoxicosis (AIT). The patient was found tachi-arrhythmic (153 beats per minute), tachypnoic (27 breaths per minute) and with intense hyperidrosis. His first blood test documented thyroid stimulating hormone (TSH) <0.01 mUI/l, free triiodothyronine (fT3) 20.0 pmol/l and free thyroxine (fT4) over 100 pmol/l. Thyroid ultrasonography revealed an enl...

Aurora kinases inhibitors Vx-680, SNS314 and ZM447439 in adrenocortical tumors

Pezzani Raffaele , Rubin Beatrice , Bertazza Loris , Cicala Maria Verena , Barollo Susi , Iacobone Maurizio , Mian Caterina , Scaroni Carla , Ulisse Salvatore , Mantero Franco

Background: Adrenocortical tumors (ACT) include benign and malignant forms. Adrenocortical carcinomas (ACC) are highly malignant neoplasms with poor prognosis and strong metastatic potential. Aurora kinase family members (AK) are serine/threonine kinase involved in the regulation of mitosis. Aurora kinase A (AKA) promotes centrosome maturation and spindle assembly, while aurora kinase B (AKB) is necessary for spindle assembly checkpoint and cytokinesis.A...

The diagnostic value of basal and calcium-stimulated procalcitonin for the diagnosis of medullary thyroid cancer: Preliminary results from a multicentric experience

Censi Simona , Di Stefano Marta , Repaci Andrea , Manso Jacopo , Pagotto Uberto , Bertazza Loris , Barollo Susi , Plebani Mario , Colombo Carla , Fugazzola Laura , Mian Caterina

Background: Calcitonin (CT) is the most sensitive marker for MTC diagnosis. By the way, many pre-analytical, analytical and post-analytical pitfalls worsen its accuracy. Procalcitonin (proCT), a CT precursor, has been suggested as a valuable complementary test in MTC diagnosis, given its stability and the reproducibility between different assay kits.Material and Methods: basal CT (bCT) and proCT (bproCT) and stimulated CT (bCT) and proCT (sproCT) (2&#821...

RET genotypes comprising specific haplotypes of polymorphic variants are associated with sporadic medullary thyroid cancer

Fugazzola Laura , Muzza Marina , Mian Caterina , Cordella Daniela , Barollo Susi , Cirello Valentina , Elisa Girelli Maria , Opocher Giuseppe , Beck-Peccoz Paolo , Persani Luca

Many single nucleotide polymorphisms (SNPs) of the RET gene have been described both in the general population and in patients with sporadic medullary thyroid cancer (sMTC), MEN2 or Hirschsprung disease. Some association studies reported a higher prevalence of these variants in the affected patients, suggesting a possible role in modifying the risk of occurrence of the disease. However, data from different cohorts of sMTC are discrepant and the aim of the present study ...

Iodine status during pregnancy in the veneto region: impact on maternal and newborn thyroid function and analysis of the nutritional and socio-economic determinants

Censi Simona , Mondin Alberto , Messina Giulia , Pedron Mariachiara , Manso Jacopo , Faggian Diego , Basso Daniela , Bertazza Loris , Barollo Susi , Marin Loris , Camilot Marta , Andrisani Alessandra , Mian Caterina

Objectives: The aim was to evaluate the iodine nutritional status in pregnant women residing in Veneto region and its associations with diet, iodine supplements and social status (nationality and education).Methods: 292 consecutive pregnant women at the third trimester of pregnancy were enrolled (≥18 years old, and resident in Veneto). Exclusion criteria were a personal history of thyroid disease and the refusal of the informed consent. Every woman...

The clinical and molecular evaluation of the GIP/GIPR axis in Medullary Thyroid Cancer (MTC)

Occhi Gianluca , Bertazza Loris , Barollo Susi , Galletta Eva , Mondin Alberto , Zovato Stefania , Iacobone Maurizio , Zilio Eleonora , Avallone Serena , Lefkimmiatis Konstantions , Di Benedetto Giulietta , Mian Caterina , Scaroni Carla , Regazzo Daniela

The glucose-dependent insulinotropic polypeptide receptor (GIPR) is a 7-transmembrane class B G-protein coupled receptor that mediates the incretin response after nutrient stimulation. Although mostly involved in metabolic disorders, in the last years an improper activation of the GIP/GIPR axis has been increasingly recognized in endocrine tumors, with a potential diagnostic and prognostic value. In Medullary Thyroid Cancer (MTC), a neuroendocrine tumor of the parafollicular C...

Prognostic significance of TERT promoter and BRAF mutations in cytologically suspicious or malignant thyroid nodules: a monocentric case series at a tertiary-level endocrinology unit

Background: Follicular-derived thyroid cancers (FDTC) generally have a good prognosis. Nonetheless, a minority of them have an aggressive behavior and develop distant metastases, with increased mortality rates. Pre-surgically available prognostic markers, able to identify this group of patients are still lacking.Materials and methods: The study involved 436 FNA samples with a malignant/suspicious cytology obtained from thyroid nodules in 436 consecutive ...
