Body parameters, such as body mass index and waist circumference, were measured. Fat distribution was evaluated using a computerized tomography scanner. The levels of serum estrogen, leptin, visfatin, and adiponectin were measured using an enzyme-linked immunosorbent assay. The expression of circulating ERs was evaluated by Western blot analysis.Results: Perimenopausal women and childbearing women with obesity exhibited lower levels of estrogen and adiponectin, in addition to a distribution of visceral fat with higher levels of leptin and visfatin. These findings reflect the current data of menopausal women, which confirms the reliability of this experimental system. However, the expression of ERα in peripheral blood was significantly enhanced in women with obesity of both childbearing and perimenopausal age. This result is contrary to the common understanding of adipose tissue, namely that ERα is protective. The expression of ERβ in the women without obesity of both childbearing and perimenopausal age was higher than in women with obesity, which coincides with the results of a previous study on adipose tissue.Conclusion: Our data fundamentally contradicts the utility of circulating ERα and ERα/ERβ evaluations in obesity studies. Because estrogen exerts pleiotropic effects on multiple tissues in the body through differential regulation of ERs, although the expression of ERβ coincides with the results of a previous study on adipose tissue, the expression levels of ERs in blood cannot be used as a diagnostic of informative tool for obesity in women.Keywords: estrogen receptors, obesity, estrogen, fat distribution, adipokines, perimenopauseFan HChen SGao BDing SZhao QLi CAsakawa TDove Medical Pressarticleestrogen receptorsObesityestrogenfat distributionadipokinesperimenopauseSpecialties of internal medicineRC581-951ENDiabetes, Metabolic Syndrome and Obesity: Targets and Therapy, Vol Volume 12, Pp 1287-1295 (2019)
