Abstract (original English)
The mechanisms underlying the association between prenatal arsenic exposure and the development of metabolic diseases remain unclear. Aberrant adipogenesis and adipokine production are associated with increased risk for the development of metabolic diseases in susceptible populations. Generation of mature adipocytes is tightly regulated by the expression of genes encoding: peroxisome proliferator-activated receptor γ (PPARG), fatty acid-binding protein (FABP4), and glucose transporter-4 (SLC2A4), and adipokines such as leptin (LEP) and adiponectin (ADIPOQ). This study aimed to investigate the expression of these genes, which are associated with the pathogenesis of metabolic diseases in newborns and children exposed to arsenic in utero. A high arsenic exposed group showed significantly decreased PPARG and FABP4 expression in cord blood samples from newborns and in saliva samples from children. By contrast, the expression of the SLC2A4 and ADIPOQ mRNA was significantly decreased in high-arsenic exposed children. Furthermore, the levels of toenail arsenic were negatively correlated with the salivary mRNA expression levels of PPARG (r = -0.412, p < 0.01), aP2 (r = -0.329, p < 0.05), and SLC2A4 (r = -0.528, p < 0.01). In vitro studies utilizing umbilical cord derived mesenchymal stem cells (UC-MSCs) as a surrogate for fetal MSCs showed that arsenite treatment (0.5 μM and 1 μM) signi
