A machine learning-based resource developed at St. Jude Children’s Research Hospital predicts which intrinsically disordered regions can drive the formation of biomolecular condensates and links those proteins to RNA biology.
Researchers identified that RASH3D19 creates a positive feedback loop that drives hyperactivity of RAS signaling and leads to tumor growth and treatment resistance
Reducing RASH3D19 also reduced tumor growth and sensitized cancer cells to KRAS inhibitors
Combining RASH3D19 blockers with KRAS inhibitors improved outcomes in preclinical models
The nuclear pore complex (NPC) controls what moves in and out of the cell nucleus. Scientists have long debated how its flexible components team up with transport factors to create a barrier that is both fast and highly selective. Using high-speed atomic force microscopy and synthetic nanopores, the researchers showed that transport factors continuously reorganize the NPCs central transporter to enhance its selectivity and speed. The findings overturn previous rigid or gel-like models of the nuclear pore complex, offering new insight into diseases—such as cancer and neurodegeneration—that are linked to NPC breakdown. They also provide a blueprint for designing smart, nanopore-based technologies for drug delivery and filtration.
