Obesity is associated with increased and dysfunctional white adipose mass. In the past, pharmacological approaches have not yielded significant results in terms of stable weight loss. Glucagon-like peptide 1 receptor (GLP-1R) agonists (GLP-1RA) used for the treatment of type 2 diabetes have more recently been proposed as anti-obesity drugs due to their relevant effects on weight loss. Furthermore, dual agonists engaging both GLP-1R and glucagon receptor (GCGR) are under invest...

Adrenocortical carcinoma (ACC) is a rare, heterogeneous malignancy with aggressive behavior and poor prognosis, particularly when metastatic at diagnosis. To date, radical surgery, possibly associated to mitotane adjuvant therapy, is considered the best option for ACC treatment. However, the mean 5-year survival rate diminishes dramatically in metastatic ACC and chemo-resistance often develops. Thus, more specific and effective drugs for ACC treatment are urgently required. Th...

Adrenocortical carcinoma (ACC) is a rare, heterogeneous malignancy with a poor prognosis, particularly when metastatic at diagnosis. To date, radical surgery, possibly associated to mitotane adjuvant therapy, is the only available treatment. However, the mean 5-year survival rate drops under 10% in metastatic ACC and chemo-resistance often develops. Thus, more specific and effective drugs for ACC treatment are urgently required. The antidiabetic drug metformin, used in type 2 ...

Obesity is associated with increased and dysfunctional white adipose tissue (WAT). Pharmacological approaches of obesity are still far from obtaining a stable weight loss. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been proposed as anti-obesity drugs due to their effects on weight loss. Furthermore, dual agonists engaging both GLP-1 and glucagon are currently under investigation for their marked effects on weight loss, although their mechanisms of action is stil...

The metabolic interplay occurring between the tumor microenvironment and cancer cells may represent a potential target for novel anti-cancer approaches. Among stromal components, adipocytes and adipose precursors have been shown to actively participate in tumor progression in several solid malignancies. In adrenocortical carcinoma (ACC), a rare endocrine neoplasia with a poor prognosis, cancer cells often infiltrate the fat mass surrounding the adrenal organ, enabling a possib...

Adrenocortical carcinoma (ACC) is a rare and aggressive tumour with a poor prognosis, characterized by radio/chemotherapy resistance. The lack of an effective medical treatment is due to the poor knowledge of the mechanisms underlying malignant tumour transformation and aggressiveness. In vitro studies on the ACC H295R cell model have demonstrated that RGZ, an antidiabetic drug belonging to the thiazolidinedione ligands of PPARgamma, blocks cell proliferation/migration ...

Fascin-1(FSCN1) is an actin-bundling protein expressed in several solid carcinomas and often associated to an invasive and aggressive phenotype as it is involved in cytoskeleton rearrangement and filopodia formation. Adrenocortical carcinoma (ACC) is a rare endocrine malignancy characterized by a poor prognosis, particularly when metastatic at diagnosis. Complete surgical resection of the tumor mass is the main therapy for ACC patients in addition to the adjuvant administratio...

Adrenocortical cancer (ACC) is a rare aggressive malignancy, with poor prognosis when metastaic at diagnosis. Recent ACC pan-genomics analysis contributed to redefine the risk groups on molecular bases, including tumor micro RNA (miR), which can be detectable not only in the primary lesion but also in the bloodstream.We develop a quantitative real-time assay for the measurement of absolute levels in plasma samples of miR483 and its mature miR483-5p form....

Besides their well-known anti-diabetic effects, the peroxisome proliferator-activated receptor γ (PPARγ) thiazolidinedione ligands (TZD) have been suggested to also display anti-inflammatory properties. The receptor role in mediating such effects is far from being elucidated. Here, we demonstrate that PPARγ is necessary for TZD to interfere with TNFα and IFNγ inflammatory activity in human endothelial cells. Different PPARγ ligands similarly inhib...

Microvascular endothelium is one of the main character and target involved in the inflammatory response. Upon specific activation, endothelial cells massively recruit Th1 IFNgamma secreting lymphocytes at the inflammatory site. In the present study, we investigate the intracellular signalling mediating TNFalpha (T) and IFNgamma (I) inflammatory response in a human endothelial cell line (HMEC-1) in vitro and the interfering effects of rosiglitazone (RGZ), a peroxisome pr...
