tumor cells

(Purdue University) Tiny nanoprobes have shown to be effective in delivering cancer drugs more directly to tumor cells -- mitigating the damage to nearby healthy cells -- and Purdue University research has shown that the nanoprobes are getting the drugs to right cellular compartments.

(Duke University Medical Center) Duke University Medical Center researchers have figured out how stem cells in the malignant brain cancer glioma may be better able to resist radiation therapy.

And using a drug to block a particular signaling pathway in these cancer stem cells, they were able to kill many more glioma cells with radiation in a laboratory experiment.

(Technische Universitaet Muenchen) Researchers at TUM, the Technische Universitaet Muenchen, have developed a new test process -- using lab-on-a-chip technology -- for establishing whether or not a cancer patient's tumor cells will respond to a particular drug.

Such sensor biochips could potentially be used in the future to aid in rapid identification of the most effective medication for individual patients.

The development of cancer involves the uncontrolled growth of normal cells of the body. Our immune system can sense the growth of the tumor cells and can usually eliminate them using direct killing mechanisms, mediated by natural killer cells and cytotoxic T lymphocytes.

However, the tumor has an arsenal of strategies to counteract the immune response that seeks to eliminate it.

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells.

Researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

A subset of tumor cells that remain after a woman with breast cancer undergoes treatment with either anti-cancer or anti-hormone therapy shows a "gene signature" that could be used to define targets for developing new drugs against the disease.

Researchers have developed the basis for a four-in-one agent that can detect, target, and disable tumor cells while also making them macroscopically and microscopically visible.

A team of cancer researchers is focusing on a new model of the disease: the permissive microenvironment, or the metastatic niche, that forms in particular tissues located far from the primary tumor, well before full metastasis takes hold.

Researchers have identified a new drug compound that appears to target tumor cells and surrounding blood vessels without the negative side effects typically associated with Cox-2 inhibitors.

If cancer cells lack a certain protein, it could be much easier for them to penetrate healthy body tissue, the first step towards forming metastases.

Scientists have discovered the previously unknown cell signal factor SCAI (suppressor of cancer cell invasion).
