摘要： Autophagy of ovarian granulosa cells is one of the reasons which results in follicular atresia. PHB2 regulates many fundamental biological processes and is pivotal in the mitophagy of cells; nevertheless, the autophagy in the bovine ovary and how PHB2 regulates the follicular cells are unknown. Here we report a protein complex that induces autophagy in bovine granulosa cells (BGCs) through the direct interaction of ER13 and PHB2. In this study, we aimed to elucidate the autophagy and the role of PHB2 in bovine ovaries using bovine primary ovarian granulosa cells (BGCs). The results showed that PHB2 in-duces BGCs autophagy because of the change in related genes and protein expression levels. In addition, the results of Co-IP and the distribution of the combination of PHB2 and ER13 showed that this complex is also indicated as an essential role of PHB2 in BGCs autophagy. Based on our results, it can be concluded that PHB2 combined with ER13 induces BGCs autophagy by targeting the mTOR pathway. This study pinpoints a novel regulatory mechanism of autophagy and demonstrates the existence of a protein complex that may underlie its roles in autophagy in BGCs.(c) 2022 Published by Elsevier Inc.
