The landmark discoveries of leptin and adiponectin firmly established adipose tissue as a sophisticated and highly active endocrine organ, opening a new era of investigating adipose-mediated tissue crosstalk. Both obesity-associated hyperleptinemia and hypoadiponectinemia are important biomarkers to predict cardiovascular outcomes, suggesting a crucial role for adiponectin and leptin in obesity-associated cardiovascular disorders. Normal physiological levels of adiponectin and leptin are indeed essential to maintain proper cardiovascular function. Insufficient adiponectin and leptin signaling

This novel study aimed to assess the serum levels of leptin and adiponectin and their ratio in patients with PanNENs and to evaluate the possible relationship between them and PanNEN’s grade or stage, including the presence of metastases. The study group consisted of PanNENs (n = 83), and healthy controls (n = 39). Leptin and adiponectin measurement by an ELISA assay was undertaken in the entire cohort.

Obesity is a risk factor for breast cancer development. A recent hypothesis suggests that the adipokines, adiponectin and leptin, are involved in breast cancer development. This prompted us to investigate the role of adiponectin and leptin in mammary carcinogenesis. Adiponectin receptors (AdipoR1 and AdipoR2) and leptin receptor (Ob-Rt, representing all the isoforms of Ob-R) proteins were detected by immunohistochemistry in in situ ductal carcinoma, invasive ductal malignancy, and healthy adjacent tissue. In addition, mRNA expression of adiponectin, AdipoR1, AdipoR2, leptin, Ob-Rt, and Ob-Rl (

BACKGROUND: Metabolic syndrome (MetS), which is characterized by insulin resistance, adipocyte accumulation, and obesity, has been linked to malignancy development. Both leptin, an adipose tissue-produced cytokine-like hormone, and adiponectin, a hormone secreted by adipose tissue, play roles in the progression of MetS. However, the presence of leptin and adiponectin is also assumed to be associated with cancer proliferation. Therefore, it is necessary to investigate the profile of leptin and adiponectin levels in MetS patients with malignancy and non-malignancy.METHODS: This was a cross-secti

Objective Adverse childhood experiences (ACEs) are associated with a greater risk of obesity and cardiometabolic disease. Adipokines, including leptin and adiponectin, play vital roles in biological processes linked to obesity and cardiometabolic risk. The adiponectin/leptin ratio may represent a marker of impaired hormonal regulation of adipose tissue. Prior cross-sectional studies suggest patterns of higher plasma leptin and lower adiponectin among adults who have experienced ACEs.

Abstract The increasing prevalence of obesity brings forward its importance as a risk factor for cancer development, particularly in the gastrointestinal tract. Obesity may trigger cancer development through several mechanisms, where metabolic deregulation of adipokines can modulate multiple oncogenic molecular pathways. Leptin and adiponectin are the most well-studied adipokines, and their imbalance can trigger different tumorigenic responses. Both epidemiologic and experimental studies have associated leptin with increased cancer risk and cell responsiveness in carcinogenesis and tumor invas

However, the causal relationship between these adipokines and the risk for RA is unclear.

Different sets of adiponectin-, leptin-, and resistin-related genetic variants were used as instruments for genetically determined adipokine levels. As body mass index (BMI) is a risk factor for RA
