Uev1A and APC/C degrade CycA to counteract oncogenic Ras, thereby protecting against cell death in polyploid Drosophila nurse cells and suppressing overgrowth in diploid germline and human colorectal tumor cells.
Independent experimental approaches demonstrate changes in TFAM binding to UVC-irradiated DNA, providing a potential mechanism for DNA damage sensing in the mitochondria.
A DNA origami nanospring introduces a force-sensing technology that enables measurement of motor protein stall forces without optical trapping, detecting force changes in kinesin KIF1A and its disease-related mutants.

TIRF imaging of CRISPR-edited human cells shows dynein–dynactin complexes move processively with motility parameters consistent with the presence of multi-dynein assemblies (>one dynein heavy chain dimer per dynactin) in cells.

HIM-5 emerges as a central scaffold that coordinates SPO-11 accessory complexes to control different aspects of meiotic DNA double-strand breaks, ensuring robust crossover formation on autosomes and the X chromosome.
