A systematic review of exposure to endocrine disruptors and energy expenditure in mice
Abstract
Exposure to endocrine disruptors (EDs) is associated with increased susceptibility to obesity and metabolic dysfunction in epidemiological and preclinical studies. Accumulating evidence supports that various EDs promote energy intake and fat storage, but little is known about how they affect energy expenditure (EE). This systematic review examined the effect of EDs on EE in murine models and on mitochondrial bioenergetics in cell-based studies. We included 12 in vivo studies, which assessed the effect of phytoestrogens, DDT, tolylfluanid, benzene, bisphenol A, bisphenol S, butyl-phthalate, deltamethrin, and the mixtures of 23 chemicals and of organophosphate flame retardants. DDT, tolylfluanid, benzene, and the mixtures of 23 chemicals and of flame retardants decreased; bisphenol A, bisphenol S, and butyl-phthalate had a neutral effect; and phytoestrogens and deltamethrin increased EE. The effects of some EDs were sexually dimorphic, dose-dependent, and interacted with diet. Nine cell-based studies were included and indicated that mitochondrial bioenergetics was impaired by tolylfluanid, bisphenol A, and DDT in muscle cells; by bisphenol AF, BDE-99, DDT, DDE, and the mixture of DDE, trans-nonachlor, and oxychlordane in adipocytes; by bisphenol A in hepatocytes; and by tributyltin in pluripotent cells. Our findings indicate that EDs affect EE in mice in a sexually dimorphic pattern and impair mitochondrial bioenergetics in cellular models which are representative of key…
How strong is the evidence?
Evidence Hub reads this as a systematic review, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
