The results apply to celecoxib, an analgesic, anti-inflammatory substance that works by inhibiting the effect of the inflammatory enzyme, Cox-2. In a study presented in Clinical Cancer Research, the research group has shown that celecoxib is also active against neuroblastoma, a type of tumour that depends on Cox-2 for its growth and proliferation.
The scientists have shown that celecoxib has an inhibitory and preventative effect on tumour development in rats. The substance also proved able to reinforce the effect of different cytostatics currently in use in the treatment of neuroblastoma.
“The painkiller can check the rapid division and growth of the cancer cells and block the blood vessels that supply the tumour with oxygen and nutrients,” says John Inge Johnsen, researcher in child cancer at Karolinska Institutet.
The researchers conclude that celecoxib is a potential anti-neuroblastoma drug, possibly in combination with other drugs.
”But it’s a matter of finding the right combination, as celecoxib can also counteract the tumouricidal effects of certain cytostatics,” says Per Kogner, Professor at Karolinska Institutet and paediatrician at the Astrid Lindgren Children’s Hospital in Stockholm.
The results from cell cultures and animals were obtained at concentrations that the scientists had previously measured in children receiving the medicine. They now plan to proceed to clinical trials, which will determine the way in which celecoxib can be used to treat neuroblastoma in children.
The research was conducted with the support of the Children’s Cancer Foundation and the Swedish Cancer Society.Publication:

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
