Researchers have peered inside breast cancers toolbox and identified a set of rogue genes that accelerates the spread of cancer from its primary site in the breast to a secondary location in bone marrow. The genes identified by the scientists are distinct from those that spawn the initial tumor, which invites speculation about whether different cancers bear unique “gene expression signatures” that increase the probability that a cancer will spread in a process called metastasis.
Metastasis occurs when cells from a primary tumor break off and invade another organ. It is the deadliest transformation that a cancer can undergo, and therefore researchers have been looking for specific genes that propel metastasis. If they can identify distinctive metastatic gene programs for different cancers, it may be possible to slow or halt metastases by targeting the proteins produced by those genes.
In the June 2003 issue of the journal Cancer Cell, researchers led by Howard Hughes Medical Institute investigator Joan Massagué at Memorial Sloan-Kettering Cancer Center, published a report showing that breast cancer metastasis to bone is mediated by a specific set of genes. Massagué collaborated on the studies with colleagues from the University of Texas Health Science Center.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
