To identify the direct effect of PE on the expression of musclin, A7r5 cells were treated with PE.
Because occupational exposure to PEs is generally higher than environmental exposure, the workplace provides an appropriate setting to study the effects of PEs on reproductive function (Kumar 2004).
Jonsson et al. (2005) examined the relationships between various urinary PEs and gonadal hormones among Swedish males, but they did not observe any significant effects of PEs on serum fT. In a study of 19 adolescents exposed to DEHP as neonates under extra-corporeal membrane oxygenation support, levels of FSH, LH, fT, and E2 were within the normal range (Rais-Bahrami et al. 2004).

To observe the effect of PE on [Ca2+]i independently of beating and of Ca2+ influx through CaV1.2, we pre-incubated and imaged the cells in media containing the CaV1.2-blocker verapamil.
Though the weak positive effect of PE on channel activity is consistent with the effects of its small surface charge, it is possible that PE also affects the channels via its ability to introduce changes in the curvature stress and lateral pressure profile of the bilayer.
To further evaluate the effect of PEs on reproductive function, other potentially important biomarkers such as other PEs (e.g., monoethyl phthalate), inhibin B, and gonadotropin-releasing hormone could be assessed in addition to measuring sperm levels.
In future studies, analysis of the effects of PE exposure on gonadotropin and steroid hormone levels should form part of an overall risk assessment for PEs.
