Events Including This Stressor
Interference with thyroid serum binding protein transthyretin and subsequent adverse human neurodevelopmental toxicity
Some phthalates have been found to competitively bind to TTR (Ishihara et al 2003; Weiss et al 2015) and have been implicated as thyroid toxicants (Boas et al 2012; Gore et al 2015; Miller et al 2009). While both animal and human data is scarce, there is some evidence for dose-dependent biochemical and morphological changes in animals (Howarth et al 2001; Liu et al 2015; O'Connor et al 2002) as well as in humans (Huang et al 2007; Meeker et al 2007).
