Caspase 3 and caspase 7 promote cytoprotective autophagy and the DNA damage response during non-lethal stress conditions in human breast cancer cells
Caspase enzymes are traditionally known for their roles in late stages of apoptosis, but growing evidence supports their function in non-apoptotic cellular processes. This study shows that caspase-3 and caspase-7 promote cytoprotective autophagy in response to non-lethal stress by modulating PARP1 activity in breast cancer cells.

SEC14-like condensate phase transitions at plasma membranes regulate root growth in Arabidopsis
The mechanisms that drive protein phase transitions are unclear. This study in plants shows that an intracellular liquid condensate formed by the lipid transferase SFH8 associates with membranes; when a short fragment of SFH8 is removed by the caspase-like protease ESP, it transforms into a solid filament that can modulate root development.
