Personal Epigentic "Signatures" Found Consistent in Prostate Cancer Patient Metastases
01/25/2013 - 11:06

In a genome-wide analysis of 13 metastatic prostate cancers, scientists at the Johns Hopkins Kimmel Cancer Center found consistent epigenetic “signatures” across all metastatic tumors in each patient. The discovery of the stable, epigenetic “marks” that sit on the nuclear DNA of cancer cells and alter gene expression, defies a prevailing belief that the marks vary so much within each individual’s widespread cancers that they have little or no value as targets for therapy or as biomarkers for treatment response and predicting disease severity.

Gold Nanoparticle Prostate Cancer Treatment Found Safe in Dogs, Study Shows
10/15/2012 - 12:56

Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, scientists at the University of Missouri have proven that a new form of prostate cancer treatment that uses radioactive gold nanoparticles, and was developed at MU, is safe to use in dogs. Sandra Axiak-Bechtel, an assistant professor in oncology at the MU College of Veterinary Medicine, says that this is a big step for gold nanoparticle research.

Epigenetic causes of prostate cancer
09/04/2012 - 10:05

In about half of all prostate tumours, there are two genetic areas that are fused with one another. When this is not the case, the exact way cancer cells originate in prostate tumours was not clear until now. Scientists at the Max Planck Institute for Molecular Genetics in Berlin, in cooperation with a team of international researchers, were able to show that the genesis of this fusion-negative prostate cancer has epigenetic causes: methyl groups are distributed differently over the DNA in the cancer cells than in healthy cells.

Prostate Cancer Survival Rates Improved Since Introduction of PSA Testing
08/23/2012 - 10:54

The routine use of prostate specific antigen (PSA) testing for screening and monitoring prostate cancer has led to early and more sensitive detection of the disease.  A new study published in The Journal of Urology® reports that in the “PSA era,” survival has improved for patients with newly diagnosed prostate cancer that has spread to the bones or other parts of the body and the disparity between African American and Caucasian men has been resolved.

Pan-fried meat increases risk of prostate cancer, new study finds
08/20/2012 - 13:58

Research from USC and the Cancer Prevention Institute of California (CPIC) found that cooking red meats at high temperatures, especially pan-fried red meats, may increase the risk of advanced prostate cancer by as much as 40 percent.

Men with prostate cancer more likely to die from other causes
07/30/2012 - 14:16

Men diagnosed with prostate cancer are less likely to die from the disease than from largely preventable conditions such as heart disease, according to a new study from Harvard School of Public Health. It is the largest study to date that looks at causes of death among men with prostate cancer, and suggests that encouraging healthy lifestyle changes should play an important role in prostate cancer management.
