Adipose tissue is an endocrine organ releasing adipokines and expressing specific markers and intracellular mediators, which regulate whole-body energy by balancing lipid accumulation and utilization through adipogenesis, the differentiation of preadipocytes into mature adipocytes associated with gradual lipid storage, and lipogenesis, the additional lipid accumulation in mature adipocytes. Adipogenesis and lipogenesis, strongly induced by insulin, occur in white adipocytes, s...

Obesity, characterized by an abnormal body fat accumulation mainly caused by a chronic imbalance between energy intake and expenditure, is a massive public health problem. Targeting excessive fat deposition in adipose tissue and ectopic fat accumulation in skeletal muscle through promoting lipid oxidation pathway may represent a promising strategy to counteract obesity. This study aims at investigating the effects of cabergoline (CAB), a dopamine agonist, on adipose and skelet...

Cushing’s disease (CD), caused by an adrenocorticotropic hormone (ACTH)-secreting pituitary tumor, is the most common form of hypercortisolism. Pituitary surgery is the first-line treatment of CD and medical treatment is an alternative second-line approach to control cortisol excess. Long-term exposure to glucocorticoids (GC) downregulates the expression of somatostatin receptor type 2 (SSTR2) but not type 5 (SSTR5) in human and mouse ACTH-secreting tumor cell cultures; t...

Cushing’s Syndrome (CS) is associated with a severe myopathy mainly affecting type 2 muscle fibres, with a higher prevalence in male subjects. The excess of glucocorticoids (GC) levels represents the most common cause of myopathy due to an alteration of protein metabolism. The non-coding post-transcriptional gene regulators muscle-specific microRNAs (miRNA) control muscle development and differentiation but when dysregulated lead to skeletal muscle (SM) disorder. The aim ...
