In vivo cell biology: following the zebrafish trend.

abstract：:Recent work has revealed that mitochondria and chloroplasts are subject to direct control by the ubiquitin-proteasome system (UPS). Ubiquitin E3 ligases are present at the outer membrane of both organelles where they mediate ubiquitination and turnover of other organellar proteins. Both organelles exhibit remarkable s...

abstract：:DNA double-strand breaks (DSBs) are major threats to the genomic integrity of cells. If not taken care of properly, they can cause chromosome fragmentation, loss and translocation, possibly resulting in carcinogenesis. Upon DSB formation, cell-cycle checkpoints are triggered and multiple DSB repair pathways can be act...
