PTEN and prostate cancer--the devil is in the doses

...functional PTEN genes showed the most invasive and aggressive cancers. These results, the researchers say, show that PTEN plays a "crucial dose-dependent role in prostate cancer tumor suppression" and that progressive reduction of gene function induces progressive changes in the quantity and quality of molecula...

Dose of PTEN protein found to determine progression of prostate cancer

...determines whether the tumor will become either an aggressive cancer or take a slow path towards microscopic features of growth, but remain benign. This new understanding of the natural history of the disease could allow researchers to develop novel clinical strategies to diagnose, treat, and possibly prevent p...

Exercise and healthy weight delay cancer even among women with highest genetic risk

...can decrease cancer risk. Women may participate in aggressive monitoring programs that try to detect any cancer as soon as possible. A number of medications to prevent cancer (such as tamoxifen) are being evaluated in high-risk women. Surgery to remove the ovaries can reduce the risk of both breast and ovarian ...

Ki-67 biomarker a strong predictor of outcome for prostate cancer patients

...rtion of prostate tumor cells with Ki-67, the more aggressive the cancer. Prior studies involved small patient numbers and did not definitively establish the usefulness of the Ki-67 biomarker. "Our study conclusively shows that Ki-67 was the most significant determinant of distant metastasis and death in prost...

At the point when the disease spreads to additional tissue types and organs, TGF-beta appears to switch from a tumor suppressor to a pro-oncogenic factor. These data have important implications for understanding epithelial ...

Sick Kids researchers link maternal folic acid intake to decrease in deadly childhood cancer

...ommonly diagnosed malignant tumour of infancy. The aggressive nature of this tumour also makes it the most common cause of cancer-related death among children one to four years old.

Unique two-part macroemulsion offers new approach to cleaning up contaminated aquifers

...in field testing the technique. "There is not an aggressive attitude toward cleaning up these spills," he said. "It's an uphill battle, and there are still a lot of old dry cleaner sites out there. But the contamination is not going to disappear by itself." Pennell sees the technique offering an efficient a...

Sick Kids researchers identify cancer stem cell for brain tumours

...ancer stem cells from different tumour types, from aggressive malignant tumours to more slow-growing benign ones, share similar properties to each other as well as to normal brain stem cells. This suggests that mutations that lead to cancer formation may have originated in the brain's own small numbers of stem ...

Fruit fly pheromone receptor first ever discovered linked to specific sexual behavior
