An increased production of ribosomes may underlie cell migration and relate to cancer metastasis, according to a new study.

A study published in Nature Communications reports that cells that increase the production of ribosomes when the cell-cycle is paused go through the epithelial-to-mesenchymal transition, allowing them to begin to migrate through the body. The authors suggest that this phenomenon is linked with cancer progression and how cancerous cells become metastatic.
