The androgen receptor (AR) function is inhibited by endocrine disrupting chemicals (EDCs) such as DDT and DDE leading to problems in embryonic development and negative health outcomes for adults. EDCs may bind in the steroid binding pocket and disrupt AR function by leading to altered receptor conformations. However, this may not be the only way EDCs interfere with the receptor. Estébanez-Perpiñá et al identified binding function 3 (BF3) as a surface bi...

In female mammals, the timing of the preovulatory LH surge depends on the combination of the positive estrogen feedback and a circadian signal which synchronizes the LH surge with the transition between the resting and active period at the end of the follicular phase, when arousal is maximal. Previous results have demonstrated that a functional biological clock, located in the suprachiasmatic nucleus (SCN), is required for optimal female fertility. In this context, we have inv...

Tributyltin (TBT) is a biocide organotin compound widely used as an antifouling in boat paints. This substance is a factor of contamination to water and food, especially marine fish. As an endocrine disruptor, TBT can interact with hormonal pathways and can induce gonadal dysfunction and glycemic dyshomeostasis; however, the effects caused by maternal exposure to TBT are scarce. Here, we investigate maternal exposure to low dose of TBT, considered safe, during pregnancy and la...

Background and Aim: A direct link between obesity and micronutrient deficiencies has been established. These nutritional dificencies are mainly caused by poor-quality diets but also due to increased demands and have been associated with a wide range of physiological and functional impairments. The aim of this study was to assess the nutritional status of obese patients and to investigate the possible association between funnctional disorders and micronutrient intake.<p cla...

Introduction: Iodine deficiency is a significant global health issue of various severity depending on the age of the deficiency. The foetal period is the most critical stage in life, negatively impacting the brain and neurodevelopment. Hence, the developing foetus is a crucial issue, and the present study focussed on iodine nutrition among pregnant women from the Faroe Islands. The need for iodine increases in pregnancy, and the recommended target for median urinary iodine con...

Tetrabromobisphenol A (TBBPA) is a brominated flame retardant and is widely used in electronic goods, plastics and furniture. TBBPA is frequently detected in water, soil, organisms and even in human breast milk. It is accessible to both the developing fetus and the nursing pups following maternal exposure. Though some regulatory agencies have asserted that consumer exposures to TBBPA are unlikely to have adverse implications for human health, the safety of TBBPA has been quest...

Background: PCBs are chemical pollutants able to promote inflammation and carcinogenesis. They can accumulate in human tissues through the food chain causing a variety of adverse health effects. The NF-E2 p45-related factor 2 (NRF2) and the aryl hydrocarbon receptor (AHR) are ligand activated transcription factors controlling pathways modulating xenobiotic metabolism. Increasing evidence indicate the involvement of AhR in regulating extracellular matrix (ECM) homeostasis. ECM ...

Background: Bisphenol A (BPA) is known to act as an endocrine disruptor in different organs. However, its impact on adrenal gland functionality is largely unknown. This also applies to its substitute substances bisphenol F (BPF) and S (BPS). Therefore, experiments addressing this subject are urgently needed.Methods: The human adrenocortical cell lines NCI-H295R and MUC-1 were treated with increasing concentrations (1 nM – 1 mM) o...
