Researchers have discovered a protein which is critical for steering melanoma cancer cells as they spread throughout the body. The malignant cells become dependent on this protein to migrate, pointing to new strategies for impeding metastasis.

The protein eIF2A is generally thought to spring into action when a cell is under stress, helping ribosomes launch protein synthesis. But according to a study published in the journal Science Advances, eIF2A has a completely different role in melanoma, helping cancerous cells control movement.

“Malignant cells that metastasize need to make their way through tissues in order to invade proximal or distant organs. Targeting eIF2A could be a new strategy to impede melanoma breaking free and seeding tumors elsewhere,” says Dr. Fátima Gebauer, corresponding author of the study and researcher at the Center for Genomic Regulation (CRG) in Barcelona.

A group of Australian scientists has uncovered a new way to fight some of the toughest cancers by targeting an overlooked cellular process called minor splicing. This tiny but vital mechanism turns out to be essential for the growth of certain tumors, especially those driven by KRAS mutations — a common but hard-to-treat culprit in cancer. By blocking minor splicing, researchers triggered DNA damage and activated the body’s own cancer-defense system, killing cancer cells while sparing healthy ones. The results in animal and human cell models are so promising that drug development is now underway, potentially paving the way for more effective and less toxic treatments across multiple cancer types.
