The tumor microenvironment can comprise more than 50% of the tumor mass and includes resident and infiltrative non-tumor cells, as well as extracellular matrix proteins, signaling molecules, and blood and lymph vessels (Balkwill et al., 2012). In recent years, the tumor microenvironment has begun to be considered both a prognostic tool and a therapeutic target (Hui and Chen, 2015). While the existence of the tumor microenvironment is well accepted and described in numerous can...

Introduction: Although the metabolic impact of Cushing’s syndrome and hypercortisolemia are well known, the metabolic impact of ACTH is less established.Objective: To identify differences in the glucidic, lipid and bone metabolism in ACTH-dependent versus ACTH-independent Cushing’s syndrome.Methods: Retrospective, cross-sectional study of 99 patients with Cushing’s syndrome (54 with ACTH-dependent Cushing’s synd...

Background: X-linked adrenoleukodystrophy (ALD) is a peroxisomal disorder of beta-oxidation that results in accumulation of very long chain fatty acids (VLCFAs) in various tissues. The clinical phenotype of X-ALD in adults is variable and involves adrenal, gonadal and nervous system dysfunction (adrenomyeloneuropathy, AMN). Patients with AMN typically develop spastic paraparesis due to progressive degeneration of the cerebral white matter.Objective: To r...

Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor derived from the thyroid C cells producing calcitonin, ac-counts for 0.6% of all thyroid cancers. It occurs either sporadically or in a hereditary form (RET mutation). MTC can be cured only by complete resection of the thyroid tumor and any loco-regional metastases. Calcitonin (CT) measurement is crucial to the early diagnosis and the follow-up of MTC. If the evaluation of stimulated CT levels is required, a prov...

Introduction: Zinc homeostasis is involved in numerous physiological and pathological conditions, ranging from type 1 and type 2 diabetes to memory impairment and cancer, and is determined by at least 28 genes, including 24 SLC (Solute Carrier) family members and 4 MTs (Metallothioneins). To explore the potential role of zinc homeostasis in MetS (metabolic syndrome) and IR (insulin resistance), we investigated 28...

Introduction: Pituitary Neuroendocrine tumours (PitNETs) present heterogenic characteristics based on their hormonal expression and secretion. While most PitNETs have a slow progression rate, a subset of them exhibit an aggressive behaviour with recurrence properties despite current surgery, radio- and chemotherapy. To explore new clinical strategies based on immunotherapy we initiated a systemic cartography of the pituitary tumour immune microenvironment (PiTME).<p class=...

Background: Tumour microenvironment (TME) can comprise >50% of the tumour mass and includes non-tumour cells like immune cells and fibroblasts, as well as extracellular matrix, signaling molecules, and blood and lymph vessels. In recent years, TME has begun to be considered both a prognostic tool and a therapeutic target. While the existence of TME is well accepted and described in numerous cancers, little is known about the TME of pituitary neuroendocrine tumours (PitNETs...

Context: Somatostatin receptor ligands (SRLs) are the cornerstone medical treatment of acromegaly, however many patients remain uncontrolled under SRLs. Well-established predictive markers of response are needed.Objective: We aimed to explore the relationship between responsiveness to SRLs, on one hand, and somatostatin (SST)2A and 5 receptor expression, adenoma granulation, and T2-weighted MRI signal intensity (T2WSI), on the other hand.<p class="ab...
