Gerber-Ferder et al. show that non-metastatic breast tumours remotely reprogram the bone marrow stroma and instruct the myeloid differentiation of long-term haematopoietic stem cells.
Dai et al. show that the transcription factor ATFS-1 interferes with mitochondrial pre-initiation transcription complex assembly and promotes mitochondrial DNA repair, thereby reducing age-dependent mitochondrial DNA damage in Caenorhabditiselegans.
Chung et al. identify the protein spartin, linked to Troyer syndrome, as a lipophagy receptor for lipid droplet clearance in vitro and in vivo. The data suggest that impaired lipid droplet turnover may contribute to Troyer syndrome development.
Systematic infection of a human multi-organoid system shows that deficiency in the host factor CIART impairs SARS-CoV-2 infection through downregulation of the RXR pathway and subsequent impairment of fatty-acid synthesis.
