Drugs that target cholesterol pathway may enhance cancer-killing potential of chemotherapy drugs

Johns Hopkins investigators are testing a way to use drugs that target a cholesterol pathway to enhance the cancer-killing potential of standard chemotherapy drugs. Their tests, in mouse models of pancreatic cancer, may yield new and more effective combinations of current and possibly new anti-cancer drugs.

Altered activity at different sites within brain network may be related to different features of depression

Depressed individuals with a tendency to ruminate on negative thoughts, i.e. to repeatedly think about particular negative thoughts or memories, show different patterns of brain network activation compared to healthy individuals, report scientists of a new study in Biological Psychiatry.

Impact of Personal Genomics Study to launch data collection phase

As genetic risk information plays an increasingly important role in the diagnosis and treatment of many diseases, private companies have made personal genomic testing for these risk factors widely available to the public. However, very little data has been gathered to understand the motivations and expectations of consumers of personal genomic services, the psychological and behavioral impact of these services, and the associated ethical, legal and social issues—until now.

Study: Functional link between two major causes of treatment failure in breast cancer

Research from The Cancer Institute of New Jersey (CINJ) shows a functional link between two major causes of treatment failure in breast cancer, showing the protein behind one of these causes plays a role in increasing the drug resistance properties of the other.

Researchers identify how neural cells build up resistance to opioid pain drugs within hours

Researchers at the University of Montreal's Sainte-Justine Hospital have identified how neural cells are able to build up resistance to opioid pain drugs within hours. "A better understanding of these mechanisms will enable us to design drugs that avoid body resistance to these drugs and produce longer therapeutic responses, including prolonged opioid analgesia", lead author Dr. Graciela Pineyro said.

Multimarker molecular stool test for colon cancer unaffected by medication, lifestyle factors

Research on an investigational DNA methylation test for colorectal cancer demonstrated that the only clinical variable that influenced test results was age, according to results presented at the AACR Annual Meeting 2012, held here March 31 - April 4.

Positive preclinical results from Cancer Therapeutics' CTX-0294945 plus Avastin study

Cancer Therapeutics, a company focused on translating cancer biology research into novel treatments for cancer, today announced positive preclinical results for CTX-0294945 as an adjuvant therapy to the cancer drug Avastin (bevacizumab - Genentech/Roche). The data is presented today in a late breaking poster at the American Association for Cancer Research (AACR) Annual Meeting 2012 in Chicago, USA.

Scientists discover why rapamycin causes diabetic-like symptoms in patients

Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing.

Novel method creates 3-D clusters of pancreatic beta-cells

Three-dimensional clusters of pancreatic beta-cells that live much longer and secrete more insulin than single cells grown in the laboratory are valuable new tools for studying pancreatic diseases such as diabetes and for testing novel therapies.

Brains of people with anorexia and obesity are wired differently

The brains of people with anorexia and obesity are wired differently, according to new research. Neuroscientists for the first time have found that how our brains respond to food differs across a spectrum of eating behaviors - from extreme overeating to food deprivation.

Gamma-linoleic acid can inhibit growth of pancreatic cancer cells

The dietary supplement gamma-linoleic acid can inhibit the growth of a subset of pancreatic cancer cells and selectively promote cancer cell death in mice, a Mayo Clinic study has found.

Stress-induced tolerance can prevent glaucoma

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness.

Removing SR-BI receptor may help protect against breast cancer

Removing a lipoprotein receptor known as SR-BI may help protect against breast cancer, as suggested by new findings presented at the American Association for Cancer Research Annual Meeting 2012 by Jefferson's Kimmel Cancer Center researchers.

Researchers discover two optimal gene targets for new colorectal cancer test

A study presented today by Mayo Clinic researchers at the American Association for Cancer Research (AACR) Annual Meeting 2012 in Chicago identified two genes that are optimal targets to be analyzed in a new noninvasive test for colorectal cancer developed by Mayo Clinic, in collaboration with Exact Sciences Corporation.

High fat diets cause damage to blood vessels earlier than previously thought

High fat diets cause damage to blood vessels earlier than previously thought, and these structural and mechanical changes may be the first step in the development of high blood pressure.

Researchers figure out how rapamycin causes diabetes

The drug known as rapamycin is widely used by cancer and transplant patients, and there are hints that it might even help us put off old age and live longer. But, it also comes with a downside: rapamycin leads to diabetes in as many as 15 percent of the people who take it.

Hepatitis B-infected patients with longer telomeres more likely to develop HCC

Hepatitis B-infected patients with significantly longer telomeres—the caps on the end of chromosomes that protect our genetic data— were found to have an increased risk of getting liver cancer compared to those with shorter ones, according to findings presented by researchers at Jefferson's Kimmel Cancer Center at the American Association for Cancer Research (AACR) Annual Meeting 2012.
