New Models of Drug-Resistant Breast Cancer Point to Better Treatments
The transplanted tumors maintain the genetic errors that caused the original cancer, even though they are growing in mice. …

The research, published in the online issue of Cancer Cell, found that when the NCOA5 gene, present in both men and women, was altered in male mice to a deficient level, a spontaneous reaction occurred producing cells that can lead to hepatocellular carcinoma, a type of liver cancer found to be two-to-four times more prevalent in men than women. Findings also showed that prior to cancer development there were occurrences of glucose intolerance, a prediabetic condition that is believed to increase the risk of type 2 diabetes in humans. …
Copper is a key player in cell growth. In order to proliferate, cells require energy, which they produce and store in the form of a molecule called ATP. Like all cells, tumor cells produce energy in two different ways: respiration, which requires oxygen, and glycolysis, which does not. Of the two, respiration is the more efficient way to make ATP…
This multi-site study co-led by Bryan R. Haugen, MD, professor of medicine and pathology at the University of Colorado School of Medicine provides the first long-term look at how these patients fared, and its findings reaffirm the performance of the Afirma Gene Expression Classifier (GEC). Haugen said "Each year, tens of thousands of patients with thyroid nodules have surgery to remove all or part of their thyroids…
"Randomised clinical trials are the best method of obtaining required documentation of the effect, safety and cost-efficacy of various methods or types of treatment employed by the health services," says Kåre Birger Haugen, chair of the programme board of the Research Council of Norway’s Programme on Clinical Research (KLINISKFORSKNING), which has provided funding to the studies. Will follow up COPD patients at home At the Norwegian Centre for Integrated Care and Telemedicine in Tromsø in Northern Norway, researchers will be studying the effect of telemedicine on people suffering from chronic obstructive pulmonary disease (COPD). Telemedicine involves treatment and monitoring activities for patients independent of the location of the medical expertise. …
"In our study, we report a change in the expression of three genes that control an important signaling pathway," said Hong Chen, a U of I professor of food science and human nutrition. The cells in the lining of the human gut turn over and are completely replaced weekly, she noted. "However, in 90 percent of colon cancer patients, an important growth-promoting signal is always on, leading to uncontrolled growth and malignancies. …
The answer, says Dr. Mak in research published today in the Journal of Experimental Medicine, is found in the way estrogen rushes in to "rescue" cells whose healthy functioning has been altered by oxidative stress, a well-established factor in cancer development…

After more than a decade of work, UC Irvine chemists have created a way to clearly identify clinically usable markers for prostate cancer in urine, meaning that the disease could be detected far sooner, with greater accuracy and at dramatically lower cost. The same technology could potentially be used for bladder and multiple myeloma cancers, which also shed identifiable markers in urine. "Our goal is a device the size of a home pregnancy test priced around $10…
