Piperonyl butoxide was given in the diet to provide levels of 0 (control), 0.02%, 0.06%, and 0.18% from 5 weeks of age of the F0 generation to 12 weeks of age of the F1 generation in mice. Select reproductive and neurobehavioral parameters were then measured. In exploratory behavior in the F0 generation, vertical time of adult females increased significantly in a dose-related manner. In behavioral developmental parameters, cliff avoidance was delayed significantly in the high-dose group in male offspring, and this effect was significantly dose-related. In female offspring, surface righting was significantly delayed in the high-dose group, and this effect was significantly dose-related. In spontaneous behavior in the F1 generation, females showed more activities in some variables in the high-dose group. Dose levels of piperonyl butoxide used in the present study produced several adverse effects in neurobehavioral parameters in mice.

Exposure to environmental factors during fetal development may lead to epigenomic modifications in fetal germ cells, altering gene expression and promoting diseases in successive generations. In mouse, maternal exposure to Di (2-ethylhexyl) phthalate (DEHP) is known to induce defects in spermatogenesis in successive generations, but the mechanism(s) of impaired spermatogenesis are unclear. Here, we showed that maternal DEHP exposure results in DNA hypermethylation of promoters of spermatogenesis-related genes in fetal testicular germ cells in F1 mice, and hypermethylation of Hist1h2ba, Sycp1 and Taf7l, which are crucial for spermatogenesis, persisted from fetal testicular cells to adult spermatogonia, resulting in the downregulation of expression of these genes. Forced methylation of these gene promoters silenced expression of these loci in a reporter assay. Expression and methylation of those genes tended to be downregulated and increased, respectively in F2 spermatogonia following maternal DEHP exposure. These results suggested that DEHP induced hypermethylation of Hist1h2ba, Sycp1 and Taf7l in fetal germ cells results in downregulation of these genes in spermatogonia and subsequent defects in spermatogenesis, at least in the F1 generation.
