The aim of the study was to evaluate the diagnostic and prognostic significance of leptin receptor isoforms in adrenal tumors. In a single-center study, 96 patients (19 with adrenal cortical carcinoma and 77 with benign tumors) underwent an adrenalectomy. A total of 14 unaffected adrenal gland tissues from kidney donors were used as controls. Fasting blood samples were collected for laboratory tests, and mRNA expressions of leptin receptor isoforms were assessed by RT-qPCR. The study analyzed correlations between mRNA expressions and clinical data and measured NCI-H295R cell proliferation via a real-time cell analyzer. All adrenal lesions expressed leptin receptor isoforms. Significantly lower LepR1 expression was observed in carcinoma tissues than in adenomas and controls ( = 0.016). Expressions of LepR3&LepR6 were correlated with overall survival ( = 0.036), while LepR2&LepR4 and LepR5 expressions were inversely related to morning serum cortisol levels ( = 0.041). Leptin reduced NCI-H295R cell proliferation ( < 0.0001). The study highlights the diagnostic and prognostic significance of leptin receptor isoforms in adrenal tumors. Specifically, LepR1 may serve as a diagnostic marker for carcinomas, while LepR3&LepR6 have potential use as prognostic markers.

Obesity is a multifactorial disease characterized by excessive accumulation of adipose tissue, resulting from an imbalance between energy intake and expenditure. Mouse models have emerged as invaluable tools for elucidating the complex genetic, environmental, and physiological mechanisms driving to obesity. This chapter provides an overview of the methodologies employed to establish and study obesity in mice, highlighting their relevance to human disease.

Hypocretin, also known as orexin, is a hypothalamic neuropeptide that regulates essential physiological processes including arousal, energy metabolism, feeding behavior, and emotional states. Through widespread projections and two G-protein-coupled receptors-HCRT-1R and HCRT-2R-the hypocretin system exerts diverse modulatory effects across the central nervous system. The role of hypocretin in maintaining wakefulness is well established, particularly in narcolepsy type 1 (NT1), where loss of hypocretin neurons leads to excessive daytime sleepiness and cataplexy.

Background: Leptin is a proinflammatory adipokine asthmatic biomarker and macrophage necroptosis are previously reported to be involved in asthmatic airway inflammation. However, whether leptin worsen airway inflammation via mediating macrophage necroptosis remains elusive. We investigated the role of the leptin on regulating macrophage necroptosis in the development of asthma.

Background & Objective: The melanocortin-4 receptor agonist setmelanotide compensates for upstream gene defects in the brain leptin-melanocortin pathway and reduces hyperphagia and obesity in selected monogenic obesity forms and Bardet-Biedl syndrome (BBS). We aimed to evaluate the short-term impact of setmelanotide treatment in BBS presenting original real-world data focusing on metabolic dysfunction-associated steatotic liver disease (MASLD) and kidney function.
Methods: This monocentric, prospective observational cohort study was performed between June and December 2023 and included patients above the age of 6 years with genetically confirmed BBS, obesity and/or hyperphagia and planned setmelanotide therapy.

Endometrial cancer (EC) is the most common gynaecological malignancy in developed countries. Early detection remains challenging, with no established plasma-based biomarkers for clinical use. This study aimed to evaluate plasma adipokines and their receptor expression as diagnostic biomarkers for EC.
