Brain microenvironment makes HER2-positive breast cancer metastases resistant to treatment

In the case of breast cancer driven by overexpression of the HER2 gene, up to 50 percent of patients treated with targeted therapies eventually develop brain metastases, which are inevitably fatal. Now a Massachusetts General Hospital-based research team has identified a novel mechanism behind the resistance to HER2- or PI3K-targeted therapies and a treatment strategy that may overcome this resistance. 

Protective, antioxidant responses appear weaker in neural stem cells from patients with Huntington disease

A multi-institutional team based at Massachusetts General Hospital has discovered how a potential treatment strategy for Huntington disease (HD) produces its effects, verified its action in human cells and identified a previously unknown deficit in neural stem cells from patients with HD.

Chronic anabolic steroid use may damage heart

Long-term anabolic steroid use may reduce the heart’s ability to pump blood and relax between beats and cause coronary artery disease, according to new research. Anabolic-androgenic steroids mimic naturally occurring testosterone, a muscle-building hormone that promotes male sexual characteristics. Since illicit use of these steroids became widespread in the American general population in the 1980s, adverse long-term effects are becoming evident.

Costs for generic hepatitis C drugs available in India would be paid back in 5 to 10 years

A research team led by a Massachusetts General Hospital investigator has found that use of the generic versions of directly-acting antiviral drugs that are available in India to treat hepatitis C virus infection is not only cost effective but actually saves lifetime treatment costs for patients in that country.

Intestinal microbial population may predict response to biologic therapy for inflammatory bowel disease

Researchers from Massachusetts General Hospital and the Broad Institute of MIT and Harvard have found that analysis of a patient's gut microbiome—the microbial population of the gastrointestinal tract—may predict the likelihood of successful treatment for inflammatory bowel disease with biologic drugs that target immune system activity.

Study shows that more than half of eligible U.S. travelers are not receiving measles immunization

A study led by Massachusetts General Hospital investigators found that 53 percent of individuals seeking pre-travel consultations at clinics across the country who were eligible to receive the measles, mumps, rubella vaccine were not vaccinated during the clinic visit.

Research staff appreciation day

Despite dreary weather, hundreds of Massachusetts General Hospital's research staff members enjoyed the annual Research Staff Appreciation Day lunch and ice cream celebration.

Study helps smokers quit and never look back

Like so many previous monumental moments in her life, Ellen Czahar, assistant and surgical coordinator in the MGH Orthopædics Department, wanted to document it with a snapshot. The empty pack of cigarettes marked the last pack she would smoke as she embarked on a happier, healthier way of life.

Molecular imaging reveals mechanism for resistance to immune checkpoint blockade

Massachusetts General Hospital investigators have identified a surprising mechanism for resistance to immune checkpoint blockade, finding in mouse models of cancer that an antibody-based drug designed to block the immunosuppressive molecule PD-1 is removed from its target T cells by macrophages within minutes of administration.

Anti-hypertension DASH diet may reduce the risk of gout

A study led by Massachusetts General Hospital investigators suggests that following a diet known to reduce the risk of hypertension and cardiovascular disease may also reduce the risk of gout.

Hypoxia reverses mitochondrial disease in mouse model

The next stage of a Massachusetts General Hospital team's investigation into the therapeutic potential of the hypoxia response—the body's reaction to reduced levels of oxygen in the blood—to treat mitochondrial disease has produced findings that are promising but also reveal some limitations.

Dietary gluten is not linked to heart risk in non-celiacs

A study led by researchers at Columbia University Medical Center and Massachusetts General Hospital revealed that dietary gluten is not associated with heart disease risk in people without celiac disease.

Silent seizures recorded in the hippocampus of two patients with Alzheimer's disease

Massachusetts General Hospital investigators have identified silent, seizure-like activity in the hippocampus—a brain structure significantly affected in Alzheimer's disease—in two patients with Alzheimer's disease and no known history of seizures.

New study shows care management program reduced health care costs in Partners Accountable Care Organization

Researchers at Partners HealthCare published a study showing that Partners Pioneer ACO not only reduces spending growth, but does this by reducing avoidable hospitalizations for patients with elevated but modifiable risks.

New imaging method may predict immunotherapy response early

A noninvasive PET imaging method that measures granzyme B, a protein released by immune cells to kill cancer cells, was able to distinguish mouse and human tumors that responded to immune checkpoint inhibitors from those that did not respond early in the course of treatment.

Standing up for science

"Science is the scaffolding, the power, the engine that drives society forward. It represents progress and knowledge and answers," said Peter L. Slavin, MD, Massachusetts General Hospital president, at an April 22 rally.

Warren Triennial honors pioneer in cancer immunology

The 2017 Warren Triennial Prize—the most prestigious research prize awarded by Massachusetts General Hospital—was presented on April 5 to James P. Allison, PhD, professor and chairman of Immunology at the University of Texas MD Anderson Cancer Center.

Nanodiamond-enhanced MRI: a new platform for a range of diagnostic and therapeutic applications

A team of investigators based at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital has devised a means of tracking nanodiamonds noninvasively with magnetic resonance imaging (MRI), opening up a host of new applications.

Enzyme treatment reduces alcohol-induced liver damage in mouse models

Massachusetts General Hospital investigators report that an intestinal enzyme previously shown to keep bacterial toxins from passing from the gastrointestinal system into the bloodstream may be able to reduce or prevent the liver damage caused by excess alcohol consumption.

Effects of alcoholism on the brain's reward system appear to be different in women than in men

A collaborative study between researchers at Massachusetts General Hospital and Boston University School of Medicine has found evidence implying that alcoholism may have different effects on the reward system in the brains of women than it does in men.
