Lysosomal dysfunction disturbs porcine oocyte maturation and developmental capacity by disorganizing chromosome/cytoskeleton and activating autophagy/apoptosis

Lysosome, an important organelle in eukaryotes, can sequester macromolecules submitted by the endocytosis and autophagy pathways for degradation and recycling. Massive macromolecular turnover is also vital to the growth and development of mammalian oocytes. However, the functional role of lysosomes in the meiotic maturation of mammalian oocytes remains largely unexplored. Here, by treating in vitro matured porcine cumulus-oocyte complexes (COCs)...
