PCR-RFLP was used to analyze the polymorphisms of MC4R, LEP, H-FABP genes in a swine breed composite (DIV2) and 4 swine breeds (Yorkshire, Landrace, Meishan, Bamei). The association study of these polymorphisms with several economic traits was carried out on a DIV2 population. The results obtained showed that MC4R/TaqI genotype had an effect for average backfat thickness (P < 0.05) and lean meat percentage (P < 0.05). At locus LEP/HinfI animals of AA genotype had lower test daily gain than that of BB (P < 0.01) or AB genotype (P < 0.05). At the H-FABP/HaeIII locus lean meat percentage of the individuals with genotype DD were higher than that with genotype dd (P < 0.05). Linkage disequilibrium analysis among MC4R, LEP and H-FABP revealed that these genes were independent. This represented two or more genes that could be combined together within one genotype in order to facilitate breeding for objective traits. In addition, a method allowing simultaneous detection of fragments of MC4R and LEP gene was developed.

Background: Cholelithiasis is the most prevalent inflammatory condition of the gallbladder. The regulation of biological processes, including energy homeostasis, and control of body weight are key mechanisms that the leptin and melanocortin pathways play a role in. Cholelithiasis is the most prevalent inflammatory condition of the gallbladder.

Background: The diagnosis of monogenic obesity is burdened by frequent variants of uncertain significance (VUS). We describe our real-life approach of variant reassessment over time and we assess whether inconclusive variants are decreasing in monogenic obesity.
Methods: We tested for monogenic obesity (genes: LEPR, POMC, ADCY3, PCSK1, CARTPT, SIM1, MRAP2, LEP, NTRK2, BDNF, KSR2, MAGEL2, SH2B1, MC4R, MC3R) in 101 children/adolescents (11.

Obesity, a significant public health concern with high prevalence in both adults and children, is a complex disorder arising from the interaction of multiple genes and environmental factors. Advances in genome-wide association studies (GWAS) and sequencing technologies have identified numerous polygenic causes of obesity, particularly genes involved in hunger, satiety signals, adipocyte differentiation, and energy expenditure. This study investigates the relationship between six obesity-related genes () and their impact on BMI, WC, HC, WHR, and emotional eating behavior in 220 Romanian adults.

Obesity, a chronic, preventable disease, has significant comorbidities that are associated with a great human and financial cost for society. The aim of the present work is to reconstruct the interactomes of non-hereditary obesity to highlight recent advances of its pathogenesis, and discover potential therapeutic targets. Obesity and biological-clock-related genes and/or gene products were extracted from the biomedical literature databases PubMed, GeneCards and OMIM.

Patients with monogenic obesity display numerous medical features on top of hyperphagic obesity, but no study to date has provided an exhaustive description of their semiology. Two reviewers independently conducted a systematic review of MEDLINE, Embase, and Web of Science Core Collection databases from inception to January 2022 to identify studies that described symptoms of patients carrying pathogenic mutations in at least one of eight monogenic obesity genes (ADCY3, LEP, LEPR, MC3R, MC4R, MRAP2, PCSK1, and POMC). Of 5207 identified references, 269 were deemed eligible after title and abstract screening, full-text reading, and risk of bias and quality assessment.
