A new prostate cancer "homing device" for drug delivery

A new prostate cancer "homing device" could improve detection and allow for the first targeted treatment of the disease. A team of Purdue University researchers has synthesized a molecule that finds and penetrates prostate cancer cells and has created imaging agents and therapeutic drugs that can link to the molecule and be carried with it as cargo.

Scientists shed new light on why pancreatic cancer drugs can fail

Cancer Research UK scientists led an international team of investigators who have discovered a new mechanism that may explain why pancreatic cancer patients are often resistant to a common chemotherapy treatment called gemcitabine, according to a study published in Science.

New evidence of how high glucose damages blood vessels could lead to new diabetes treatments

New evidence of how the elevated glucose levels that occur in diabetes damage blood vessels may lead to novel strategies for blocking the destruction, Medical College of Georgia researchers say.

Peregrine's PS-targeting antibodies highlighted in AACR Annual Meeting studies

Peregrine Pharmaceuticals, Inc. has reported that two preclinical studies presented during the AACR 100th Annual Meeting 2009 provided further confirmation of the immunomodulatory mechanisms contributing to the anti-tumor activity of its phosphatidylserine (PS) targeting antibodies.

New drug to target tumor cells and blood vessels

Researchers at the University of Southern California 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.

Brain metastases hijack neuron-supporting cells to resist chemotherapy

Cancer that spreads to other organs finds a particularly inviting hideout in the brain, where these metastases are usually far harder to treat than they are in other locations.

Angiogenesis inhibitors, study points to limitations, solutions

A new generation of cancer drugs designed to starve tumors of their blood supply - called "angiogenesis inhibitors"-succeeds at first, but then promotes more invasive cancer growth-sometimes with a higher incidence of metastases, according to a new study in animals.

Targeted nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light. When heated with lasers, the actively targeted hollow gold nanospheres did eight times more damage to melanoma tumors in mice than did the same nanospheres that gathered less directly in the tumors.

Mouse model mimics hyperglycemia, aids in diabetes research

UT Southwestern Medical Center researchers have genetically engineered a laboratory mouse in which pancreatic beta cells can regenerate after being induced to die.

Noninvasive screening test may detect narrowing in intracranial stents

Great advances have been made in treating blockages in the arteries of the brain using angioplasty to widen the narrowed artery and a stent to hold the artery open.

Peptide loaded gold nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research.

Cell-building discovery offers great potential for basic cell biology, drug and tissue research

Brown University biomedical engineers can now grow and assemble living microtissues into complex three-dimensional structures in a way that will advance the field of tissue engineering and may eventually reduce the need for certain kinds of animal research.

FDA grants compassionate case for use of novel wet age-related macular degeneration treatment

NeoVista, Inc., announced today that the U.S. Food and Drug Administration (FDA) had approved the company's "compassionate case" waiver to utilize its novel wet age-related macular degeneration (AMD) treatment on a patient with an advanced form of the disease who did not meet criteria for inclusion into current NeoVista investigational treatment protocols.

New evidence shows that the heart beats to its own drummer

They've uncovered some of the molecular circuitry within the cardiovascular system itself that controls the daily rise and fall of blood pressure and heart rate. The findings might also explain why commonly used diabetes drugs come with cardiovascular benefits, according to the researchers.

Reprogrammable cell type depends on a single gene to keep its identity

Scientists at St. Jude Children's Research Hospital have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade it.
