Regulation of autophagy during mitosis

Abstract

Based on observations of mitosis process, it has been implied that autophagy is repressed. Because the integrity of chromosomes and proteins are significant for cell cycle, the repression of autophagy serves as a protection. However, the mechanistic detail of whether and how autophagy is regulated during mitosis remains controversial. In this review, we aim to analyse and review the recent literature on the regulation of autophagy during mitosis. According to researches, autophagy is repressed via inhibitory phosphorylation of autophagy genes by CDK1, CUL4-RING ubiquitin ligases-mediated and WIPI2 polyubiquitination and proteasomal degradation. In addition, the recent evidence that indicates autophagy is repressed will be reviewed.
