Genetic markers in surrounding tissues linked to breast cancer tumor grade, presence of metastases

05-15-2007 · EurekAlert!

Researchers have identified genetic markers on several chromosomes in the tissue surrounding tumor cells that are associated with breast cancer tumor grade and the presence of lymph node metastases, according to a study in the May 16 issue of JAMA.

New genetic test predicts risk of metastasis in patients with deadly eye cancer
11-15-2006 · EurekAlert!
Doctors at UCLA's Jules Stein Eye Institute have pioneered the first technique to biopsy tumor tissue from the living eye and test it for a genetic marker linked to aggressive metastasis. The new test is life-changing, because ocular melanoma doesn't just cause blindness -- it can kill you in as quickly as a year.

UT Health Science Center researchers decoding saliva to detect breast cancer
01-10-2008 · EurekAlert!
Researchers at The University of Texas Health Science Center at Houston can identify and quantify specific protein markers in human saliva to provide an early, non-invasive diagnosis of breast cancer, according to a study appearing today in the journal Cancer Investigation. The study is being applied to "lab-on-a-chip" technology that may bring this type of diagnostic test -- capable of detecting the presence of cancer before a tumor forms -- into everyday use.

New genetic marker characterizes aggressiveness of cancer cells
06-25-2007 · EurekAlert!
Levels of a small noncoding RNA molecule appear to define different stages of cancer better than some of the "classical" markers for tumor progression. By suppressing genes that are active in the developing embryo, silenced just before birth, and re-activated years later in many advanced cancers, the let-7 family of microRNAs appears to prevent human cancer cells from reasserting their prenatal capacity to divide rapidly, travel and spread.

Newly created cancer stem cells could aid breast cancer research
08-13-2007 · EurekAlert!
Scientists have created breast cancer stem cells in culture by isolating and transforming a particular population of cells from normal human breast tissue. After being injected with just 100 of these transformed cells, mice develop tumors that metastasize. When scientists performed the same transformation process on a slightly different population of cells from the identical human breast tissue, the resulting cancer cells were 10,000 times less potent as tumor initiators and could not move to other tissues.

Unique estrogen receptor linked to metastatic breast cancer
11-01-2006 · EurekAlert!
Breast cancer awareness month may have passed, but researchers remain focused on the disease with a new study showing that a unique estrogen receptor found in breast cancer tumors is a predictor of tumor size and metastases. The study, led by researchers at Rhode Island Hospital and Brown Medical School, is published in the Nov. 1 issue of Clinical Cancer Research.

Breast cancer cells have to learn to walk before they can run
12-31-2007 · EurekAlert!
Early-stage breast cancer that has not yet invaded the surrounding tissues may already contain highly motile cells, bringing the tumor one step closer to metastasis, report researchers at the Salk Institute for Biological Studies.

A genetic 'gang of 4' drives spread of breast cancer
04-11-2007 · EurekAlert!
Studies of human tumor cells implanted in mice have shown that the abnormal activation of four genes drives the spread of breast cancer to the lungs. The new studies by Howard Hughes Medical Institute researchers reveal that the aberrant genes work together to promote the growth of primary breast tumors. Cooperation among the four genes also enables cancerous cells to escape into the bloodstream and penetrate through blood vessels into lung tissues.

Almac Diagnostics announces pioneering genetic research on ductal carcinoma in situ
08-08-2007 · EurekAlert!
Today Almac Diagnostics announced a major study analyzing ductal carcinoma in situ tissue samples using its novel Breast Cancer DSA microarray. DSA research tools focus on the transcriptome of an individual disease, in this case breast cancer, and contain significant additional data relevant to the disease of interest that is not available on other generic microarrays.

Fat kills cancer
07-03-2007 · EurekAlert!
Researchers in Slovakia have been able to derive mesenchymal stem cells from human adipose, or fat, tissue and engineer them into "suicide genes" that seek out and destroy tumors like tiny homing missiles. This gene therapy approach is a novel way to attack small tumor metastases that evade current detection techniques and treatments, the researchers conclude in the July 1 issue of Cancer Research, a journal of the American Association for Cancer Research.

Jefferson pharmacologist says biomarker discovery bodes well for better cancer diagnostics
05-01-2007 · EurekAlert!
A pharmacologist at the Kimmel Cancer Center at Jefferson says that new findings suggesting a genetic marker can help distinguish between chronic pancreatitis and pancreatic cancer and gauge who will do well with cancer treatment have important implications for improved cancer diagnostics and tumor profiling. In an editorial he co-authored May 2 in JAMA, Scott Waldman, M.D., Ph.D., says that researchers at Ohio State University have identified "a new level of biological regulation."
