The aim of this study was to investigate the relationship between the leptin receptor (LEPR) polymorphism/serum leptin level and preeclampsia. The prevalence of a single nucleotide polymorphism in the LEPR gene exon 14 at -656 and the serum leptin concentrations in 97 preeclamptic pregnant mothers were compared to those of 110 healthy controls. The Lys656Asn genotype and Lys656Asn + Asn656Asn f...

Only a fraction of all smokers develop chronic obstructive pulmonary disease (COPD), suggesting a large role for genetic susceptibility. The leptin receptor (LEPR) is present in human lung tissue and may play a role in COPD pathogenesis. The present study examined the association between genetic variants in the LEPR gene and lung function decline in COPD. In total, 429 European Americans were r...

The adipocyte-derived hormone leptin is required for normal pubertal maturation in mice and humans and, therefore, leptin has been recognized as a crucial metabolic cue linking energy stores and the onset of puberty. Several lines of evidence have suggested that leptin acts via kisspeptin expressing neurons of the arcuate nucleus to exert its effects. Using conditional knockout mice, we have pr...

The leptin (LEP) and its receptor (LEPR) regulate food intake and energy balance through hypothalamic signaling. However, the LEP-LEPR axis seems to be more complex and its expression regulation has not been well described. In pigs, LEP and LEPR genes have been widely studied due to their relevance. Previous studies reported significant effects of SNPs located in both genes on growth and fatnes...

OBJECTIVE The purpose of this study was to investigate the impact of the interactions among CX3CL1 (rs170364 and rs614230), LEPR (rs6700896), and IL-6 (rs2066992) polymorphisms on the risk of coronary artery disease (CAD) in Chinese Han population. METHODS 120 CAD patients and 109 healthy controls were enrolled in the study. Polymerase chain reaction (PCR) and direct sequencing methods were u...

BACKGROUND AND AIM Genetic polymorphism has been implicated as a factor for the occurrence of non-alcoholic fatty liver disease (NAFLD). This study attempted to assess whether polymorphisms in the leptin receptor (LEPR) gene and its combined effect with patatin-like phospholipase domain-containing protein 3 (PNPLA3/adiponutrin) are associated with risk of NAFLD. METHODS A total of 144 biopsy-...

BACKGROUND Colorectal cancer (CRC) is the second most commonly diagnosed cancer and the fourth leading cause of cancer-related mortality around the world. OBJECTIVES With regard to the role of obesity in colorectal cancer (CRC) and the role of leptin in obesity, we investigated whether leptin (LEP) and leptin receptor (LEPR) gene variants are associated with CRC risk. PATIENTS AND METHODS W...

BACKGROUND The Leptin receptor (LEPR) Gln223Arg gene polymorphism has been associated with an increased susceptibility to Type 2 diabetes mellitus (T2DM). Results from various studies, however, are inconsistent. OBJECTIVE AND METHODS To better elucidate the association of LEPR Gln223Arg gene polymorphism with T2DM in the Chinese population, a meta-analysis of 3,367 subjects from seven indepen...

Increased adiposity is a major risk factor for cardiovascular disease and NIDDM (1). Genetic determinants of the degree of adiposity and body fat distribution have been demonstrated by twin and adoption studies, and the heritability (h) of obesity has been estimated to be as high as 0.90 (2). However, the major genes underlying the heritable contribution to body fatness in humans have remained ...

Dermal papilla (DP) is the key mesenchymal niche cell type, that regulates cyclic regeneration of hair follicles by orchestrating paracrine signaling crosstalk with epithelial progenitors. We discovered leptin receptor (Lepr) a robust marker gene adult DP fibroblasts in mice and constitutive Cre inducible CreER genetic tools, whose activity follows expression Lepr isoform B, can efficiently tar...
