SOCS1 molecule prevents cancer-causing activity of cytokines, discover researchers

Canadian researchers have discovered a novel molecular mechanism that prevents cancer. In the December 11 edition of the prestigious journal Molecular Cell, scientists from the Universit- de Montr-al and the Universit- de Sherbrooke explain how they found that the SOCS1 molecule prevents the cancer-causing activity of cytokines, hormones that are culprits in cancer-prone chronic inflammation diseases such as Crohns, in smokers and people exposed to asbestos.

Rice, TMC team wins stimulus funds for nanoparticle standardization

One of the promises of nanomedicine is the design of tiny particles that can home in on diseased cells and get inside them. Nanoparticles can carry drugs into cells and tag cells for MRI and other diagnostic tests; and they may eventually even enter a cell's nucleus to repair damaged genes. Unfortunately, designing them involves as much luck as engineering.
