Researchers examine mechanisms that help cancer cells proliferate

DALLAS — Sept. 1, 2009 — A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.

PET/CT Scans May Help Detect Recurring Prostate Cancer Earlier

ScienceDaily (Sep. 1, 2009) — A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed.

Markers Can Predict More Aggressive Pancreatic Tumors
Study finds impaired blood flow and high metabolism predict poor survival

MONDAY, Aug. 31 (HealthDay News) -- Blood flow is impaired and metabolism is enhanced in pancreatic tumors, and a high ratio of metabolism to blood flow predicts poor survival, according to a study published online Aug. 25 in Clinical Cancer Research.

Tumors Feel The Deadly Sting Of Nanobees

ScienceDaily (Aug. 31, 2009) — When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Delivery Of Cancer-fighting Molecules Improved

ScienceDaily (Aug. 27, 2009) — Small interfering RNA (siRNA), a type of genetic material, can block potentially harmful activity in cells, such as tumor cell growth. But delivering siRNA successfully to specific cells without adversely affecting other cells has been challenging.
