Title	Mechanisms of ROS-induced mitochondria-dependent apoptosis underlying liquid storage of goat spermatozoa
Description	Liquid storage of spermatozoa is important for artificial insemination and herd genetic breeding. However, the extending time of storage inducing rapid decline of spermatozoa quality limits the development of this technology. The molecular mechanisms underlying liquid storage of spermatozoa remain largely unexplored. In this study, the effects of liquid storage on functional quality of spermatozoa were assessed in goat (Capra hircus). The time-dependent decline of spermatozoa motility showed a strong correlation with the significant increase of apoptosis. Moreover, apoptosis-related ultrastructural changes were observed, especially the defect in mitochondria. Meanwhile, significant decrease of mitochondrial membrane potential and expression changes of mitochondrial apoptosis-related proteins indicated mitochondrial dysfunction and activation of mitochondrial apoptotic pathway. Notably, the abnormal high level of reactive oxygen species (ROS) caused by liquid storage resulted in the oxidative damage to mitochondria and accelerated mitochondria-dependent apoptosis, which was demonstrated by addition of ROS scavenger N-acetylcysteine. Furthermore, critical differentially expressed proteins involved in mitochondria-dependent apoptosis and antioxidant defense were identified and profiled by quantitative proteomic analysis, facilitating the understanding of molecular regulation of ROS-induced mitochondria-dependent apoptosis. These outcomes provide insights into the mechanisms underlying liquid storage of goat spermatozoa and enhance the progress of semen storage technology.
