Genetic polymorphisms in obesity‐related genes and endometrial cancer risk
AssociationN=2,960Xiaoli Chen et al.(2012)· Cancer

This case-control study of 1,028 endometrial cancer cases and 1,932 controls from Shanghai evaluated 87 SNPs in five obesity-related genes (ADIPOQ, ADIPOR1, ADIPOR2, LEP, LEPR). Three ADIPOQ SNPs (rs3774262 OR=0.68, rs1063539 OR=0.66, rs12629945) and one LEP SNP (rs2071045 OR=0.70) were significantly associated with reduced endometrial cancer risk. The ADIPOQ variants were also associated with lower body weight, waist circumference, and BMI in controls, suggesting a potential mechanism through obesity.

About LEP

This gene encodes a protein that is secreted by white adipocytes into the circulation and plays a major role in the regulation of energy homeostasis. Circulating leptin binds to the leptin receptor in the brain, which activates downstream signaling pathways that inhibit feeding and promote energy expenditure. This protein also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis, reproduction, bone formation and wound healing. Mutations in this gene and its regulatory regions cause severe obesity and morbid obesity with hypogonadism in human patients. A mutation in this gene has also been linked to type 2 diabetes mellitus development. [provided by RefSeq, Aug 2017]
