Using high-throughput light-sheet microscopy, Dent et al. study 3D cancer cell morphogenesis. Environmental cues modulate the opposing roles of non-muscle myosin II (myosin) and microtubules, with varied impacts on RhoGEFs FARP1 and TIAM2. The study underscores the critical interplay between cytoskeletal regulators and the microenvironment, enhancing our understanding of cell behavior in diverse settings.

The soil microbiome modulates the sorghum root metabolome and cellular traits with a concomitant reduction of Striga infection
The soil microbiome protects sorghum, and likely other crops, from infection with the root parasite Striga hermonthica. Kawa et al. show that soil-borne bacteria modify sorghum root development and root exudate content, likely preventing Striga from penetrating sorghum. This study provides […]
The nociceptive activity of peripheral sensory neurons is modulated by the neuronal membrane proteasome
Proteasomes are critical for sensory neuron function. Villalón Landeros et al. uncover a specialized proteasome in somatosensory neurons called the neuronal membrane proteasome (NMP). The NMP mediates crosstalk between somatosensory neurons to modulate sensitivity to stimulation. Inhibition of the NMP reduces […]
Neospora caninum, a Protozoan Killing Dogs, “Might Be Key” to “Total Regression of Tumors”
Neosporosis, caused by the intracellular parasite Neospora caninum, presents a significant challenge in veterinary medicine, leading to serious and life-threatening neurological issues in dogs, and costing the industrial cattle industry billions each year. N. caninum does not infect humans, making […]
