Designer nano luggage to carry drugs to diseased cells
Scientists have succeeded in growing empty particles derived from a plant virus and have made them carry useful chemicals. The external surface of these nano containers could be decorated with molecules that guide them to where they are needed in the body, before the chemical load is discharged to exert its effect on diseased cells. The containers are particles of the Cowpea mosaic virus, which is ideally suited for designing biomaterial at the nanoscale.

Brain tumor's 'grow-or-go' switch discovered
High energy levels cause glioblastoma cells to proliferate; low levels cause them to grow less and to migrate. This study discovered that a molecule called miR-451 coordinates this grow-or-go behavior, which is closely linked to the cells' ability to invade and spread. Thus, the molecule might be a biomarker for predicting survival in patients with glioblastoma multiforme and may serve as a target to develop drugs to fight these tumors.

Exploiting the architecture of cancers may lead to their destruction
To grow larger, solid tumors require a network of blood vessels to nourish them. Chemotherapy exploits these vessels to deliver toxic drugs, but is inefficient if the drugs cannot pass quickly enough from the bloodstream into the tumor. A new study describes a way of transiently making the tumor blood vessels leakier, allowing more efficient drug uptake. This work may ultimately enhance delivery of chemotherapies into tumor tissue.

Discovery Of Opposing Functions Of A Key Molecule In The Development Of Organisms Could Benefit Cancer Research
Scientists headed by ICREA researcher Marco Milan, at the Institute for Research in Biomedicine (IRB Barcelona), reveal a surprising new function of Notch protein that contrasts with the one known to date. Found in the cell membrane, this protein activates a signalling pathway that regulates the expression of genes that make the cell divide, grow, migrate, specialise or die...

Nanoparticles Provide A Targeted Version Of Photothermal Therapy For Cancer
In a lecture he delivered in 1906, the German physician Paul Ehrlich coined the term Zuberkugel, or "magic bullet," as shorthand for a highly targeted medical treatment. Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today...
