Abstract

Propagation of a species requires periodic cell renewal to avoid clonal senescence. Liu et al. (2010) now describe a new mechanism of cell renewal in budding yeast, in which damaged protein aggregates are transported out of the daughter buds along actin cables to preserve youthfulness.

摘要

物种的繁殖需要周期性的细胞更新以避免克隆性衰老。刘等人（2010）现在描述了出芽酵母中细胞更新的一种新机制，其中受损的蛋白质聚集体沿着肌动蛋白电缆被运出子芽，以保持年轻。
