Giant cell tumors are rare, benign but aggressive and locally invasive tumors that usually affect the long bones in the limbs, typically presenting during the 3rd or 4th decade of life. Giant cell tumors of the skull are exceedingly rare, and less than 150 cases have been reported to date, of which less than 10 were described in the pediatric population. Here, we present the case of a 14 year old female that progressively developed severe headaches, blurr...

Background: Hypocaloric diets reduce the risk for type 2 diabetes (T2D) in obese subjects. However, there is a large inter-subject variability in the response to these interventions. The factors affecting this variability remain poorly understood. We and others reported that high plasma apoB-lipoproteins predict risk factors for, and incidence of, T2D in obese subjects independent of adiposity or fat distribution.Objective: To test the hypothesis that pl...

The hypoxia, associated to intra-uterine growth restriction, is related to high concentrations of IGFBP1 and unchanged concentrations of IGF1 in animals. Nevertheless, during threatening life events, low IGFI concentrations and high IGFBP1 concentrations was reported. Furthermore, severe hypoxia increased the IGF1R expression of the neuronal growth cones in the ovine fetal brain. No information is available regarding the regulation of the IGF system by the acute hypoxia in hum...

Maternal obesity during pregnancy is associated with several metabolic impairments in offspring, some of them evidenced from early infancy. Some reports have demonstrated that offspring of obese rats, whose obesity was induced by high fat diet consumption, have an increase sympathetic tone and increased norepinephrine (NE) content in kidney, liver and ovary. We recently reported that maternal administration of metformin prevents the increase in ovarian NE in offspring when the...

Kinases represent a main therapeutic targets in cancer treatment as their impairing is related to tumor growth and progression. Despite the increasing evidence that tumor microenvironment (TME) signaling influences the behavior of surrounding cancer epithelial cells, still little is known about what changes in stromal cells influence tumor cells’ behavior. TNBC patients are still lacking an effective therapy, as not much is known about the biology of this BC tumor subtype...

With congenital hypopituitarism, the clinical manifestations of pituitary hormone deficiencies usually appear during infancy or early childhood. Typically, one or more anterior pituitary hormones are deficient, and the most severe manifestations include neonatal hypoglycemia, electrolyte imbalances and failure to thrive. We present the case of a 43 year old male, with cardiovascular and metabolic comorbidities (arterial hypertension, type 2 diabetes mellitus), with no prior ho...

Pineal germinomas account for the majority of intracranial germ cell tumors. Surgery and radiation are usual management options, and secondary hypopituitarism can ensue after both. Diabetes insipidus is particularly common after surgical removal of pineal tumors, but improvement in polyuria and polydipsia years after surgery is exceedingly rare. Here, we present the case of a 49-year-old male, who was diagnosed with a pineal germinoma at the age of 20, which was surgically rem...

Introduction: Broncho-Pulmonary Neoplasms (BP-NENs) are rare neoplasms arising from neuroendocrine cells of the respiratory epithelium. Since previous studies in our lab have demonstrated the efficacy ofEverolimus, approved for BP-NENs treatment, and Dinaciclib, a Cyclins and CdKs inhibitor, on monolayer system we have investigated if a more complex tumour system could generate a change in drugs effects and cell resistance. Therefore, through the use of 3D culture model, we ha...

Purpose: Skeletal muscle has been recognized as a thyroid hormones (THs) target for contractile function, regeneration, metabolism and glucose disposal. Despite a role in regulating muscle development has been described, little is known about the role of THs in regulating muscle homeostasis in a pathological state such as food deprivation induced atrophy. The purpose of this study is to evaluate whether thyroid hormones may hamper the fasting induced skeletal muscle atrophy an...

Background: Skeletal muscle is known to be a target of THs, regulating oxygen consumption, fiber composition, calcium mobilization and glucose uptake. However, a possible role for THs in muscle homeostasis and cellular metabolism under pathological has never been investigated. Food deprivation induces skeletal muscle atrophy, causing metabolic changes, and forcing the tissue to utilize fatty acid as the main oxidation substrate. Aim of this project was to understand whether T3...
