FDA clears MammaPrint test for marketing

The Food and Drug Administration (FDA) has cleared for marketing a test that determines the likelihood of breast cancer returning within five to 10 years after a woman's initial cancer. It is the first cleared molecular test that profiles genetic activity.

Direct synthesis of polymer nanocapsules with a noncovalently tailorable surface

To accurately transport pharmaceutical agents to their specific target organs or cell types, you need a good carrier: nanoscopic capsules with surface elements that can "recognize" the target in question could do the trick.

Researchers identify human pancreatic cancer stem cells

Researchers at the University of Michigan Medical Center have, for the first time, identified human pancreatic cancer stem cells. Their work indicates that these cells are likely responsible for the aggressive tumor growth, progression, and metastasis that define this deadly cancer.

Peptide vaccine fights off breast tumors with help of bacteria-mimicking agents

With the help of immune system-stimulating molecules that mimic bacterial components, researchers have used a type of cancer vaccine to both delay and prevent breast tumors in mice.

Probing proteins can lead to better understanding of anti-tumor agents

There are a number of naturally occurring chemicals that are used in phototherapy of skin diseases. Hypocrellin A (HA), which can be extracted from a parasitic fungus, has been taken orally as a folk medicine for several centuries in China.

Second-generation dendrimer disintegrates upon command

Dendrimers, highly branched, spherical polymers, have demonstrated their utility as drug and imaging agent delivery vehicles for use in detecting and treating cancer, with several dendrimer-based agents nearing human clinical trials.

Design of gold nanoparticles for magnetic resonance imaging

Molecular complexes containing the element gadolinium are proven agents for increasing the diagnostic utility of magnetic resonance imaging (MRI), but their use in detecting small tumors is limited by the relatively weak signal these agents produce.

Polymer nanoparticles for immunotherapy from encapsulated tumor-associated antigens and whole tumor cells

Using a biodegradable nanoparticle as a means of delivering tumor cell debris and proteins to the immune system, investigators at Yale University have developed a promising new method for creating therapeutic anticancer vaccines.

FoxOs shown to be potential new targets for cancer drugs

In an elegant, multiple-gene knockout experiment, a team of Boston scientists has discovered that a trio of molecules, called FoxOs, are fundamentally critical in preventing some cancers, maintaining blood vessel stability, and in keeping blood-forming stem cells healthy.
