Effects of Vitamin E on the Epithelial-Mesenchymal Transition in Testicular Development Exposed to Valproic Acid

SUMMARY: In testicular differentiation, somatic cells must adopt a specific destiny towards sustentacular, peritubular and interstitial cells, being fundamental for the morphogenesis of seminiferous tubules, mediated by morphogens such as Desert Hedgehog (DHH), insulin-like growth factor-1 (IGF-1) a...

The objective of the study was to evaluate the epithelial-mesenchymal transition (EMT) in the testicular development of mice exposed to VPA and VE. 12 groups of pregnant female mice were formed that were separated by days post-coital (dpc) at 12.5 dpc, 17.5 dpc and 6 weeks postnatal, each one subdivided into 4 groups of 5 pregnant women each. Subgroups received different treatments from the beginning to the end of gestation orally: 600 mg/kg of VPA, 600 mg/kg of VPA and 200 IU of VE, 200 IU of VE and the control group 0.3 mL of 0.9% physiological solution.
