Spermatozoa must undergo a complex maturation process within the female genital tract known as capacitation. This process entails the phosphorylation or dephosphorylation of various proteins, and multiple signaling pathways are recognized to play a role. The present study aims to identify alterations in the expression of proteins related to the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT) signaling pathway and assess sperm functions during capacitation.

Article Synopsis
  • - The study investigates how perfluorooctanoic acid (PFOA), an environmental contaminant, negatively impacts sperm functions like motility and capacitation in boar sperm by examining specific proteins called Rab proteins.
  • - Findings show that exposure to PFOA significantly reduces sperm motility and is linked to changes in Rab proteins, particularly Rab14, Rab25, and Rab34, which are crucial for sperm development and the acrosome reaction.
  • - The research suggests that the alterations in Rab protein activity could serve as biomarkers for measuring the reproductive toxicity of environmental toxins like PFOA, potentially leading to lower pregnancy rates.
