Glucocorticoid receptor (NR3C1) gene polymorphisms are associated with age and blood parameters in Polish Caucasian nonagenarians and centenarians.

Introduction: Polymorphism of the glucocorticoid receptor gene (NR3C1) may modify protein abundance or function and therefore disturb human homeostasis.

Methods: Variant frequencies of the three NR3C1 polymorphisms, rs2963154, rs10515522 and rs2918418, selected in silico as associated with longevity, was analyzed in 552 DNA samples from 95 to 106-year-old individuals and in 284 samples of cord blood DNA from newborns.

Results: Frequencies of the TT genotypes of rs2963154 and rs10515522, and of the rs291841 CC genotype, were higher in the long-lived study subjects (p = 0.

High-fat, cholesterol-rich diet affects leptin expression in the aortic layers.

Leptin is stated to be an important mediator between obesity and cardiovascular disease. However, whether leptin location in the aorta is dependent on diet and its atherogenic character is still unknown. This study examined the relationship between a high-fat diet with or without cholesterol and the expression of leptin in aortic layers.
