Experimental cancer drug shows promise for Parkinson’s

A drug originally developed for prostate cancer may have exciting potential for treating Parkinson’s. The study, funded by Parkinson’s UK, suggests that the drug, tasquinimod, which is not yet on the market, works by controlling genes that may cause Parkinson’s. This happens when the drug interacts with a protein inside […]

New tools illuminate mechanisms behind overlooked cellular components’ critical roles

In two papers published in the journal Cell, researchers from multiple Princeton departments report on the conditions that lead to the formation of membraneless organelles and the impact that the formation has on cellular DNA. Clifford Brangwynne, associate professor of chemical and biological engineering and leader of the research teams, said the […]

The long and short of CDK12

Mutations in the BRCA1 and BRCA2 genes pose a serious risk for breast and ovarian cancer because they endanger the genomic stability of a cell by interfering with homologous recombination repair (HR), a key mechanism for accurately repairing harmful double-stranded breaks in DNA. Without the ability to use HR to […]

New drug combination could be more effective against melanoma

A class of cancer drugs called protein kinase inhibitors is one of the most effective treatments for melanoma. However, in many cases, tumors eventually become resistant to the drugs and cause a relapse in the patient. A new study from MIT suggests that combining kinase inhibitors with experimental drugs known […]

Study: Immunotherapy Better than Chemotherapy for Subtype of Head and Neck Cancer

A randomized clinical trial involving 97 medical centers in 20 countries, including Moores Cancer Center at UC San Diego Health, found that treating patients who have chemotherapy-resistant head and neck cancer with the immunotherapy drug pembrolizumab is more effective and less toxic than standard chemotherapy, reports an international team of […]

First Jellyfish Genome Reveals Ancient Beginnings of Complex Body Plan

Jellyfish undergo an amazing metamorphosis, from tiny polyps growing on the seafloor to swimming medusae with stinging tentacles. This shape-shifting has served them well, shepherding jellyfish through more than 500 million years of mass extinctions on Earth. “Whatever they’re doing has really worked for them,” said David Gold, an assistant professor […]

Study reveals new role for methotrexate in fighting cancer

A study of the dual pathways that process the essential vitamin folate by Weill Cornell Medicine investigators unexpectedly revealed a new way the cancer drug methotrexate works and may suggest strategies to boost its cancer-killing effects. For the study, published in Cell, the investigators used genome editing and biochemical experiments […]

Microglia: Teasing Out Diversity

Immune cells known as microglia have been found to protect the brain from injury and infection and are critical during brain development, helping circuits wire properly. They also seem to play a role in disease—showing up, for example, around brain plaques in people with Alzheimer’s. In an ambitious study, perhaps […]

Plant’s recycling system important in sickness and in health

Reduce, reuse, recycle. Or just stick with recycle. A plant relies on cellular machinery to recycle materials during times of stress, but that same machinery has a remarkable influence on the plant’s metabolism even under healthy growing conditions, according to new research from Washington University in St. Louis. Autophagy is […]

Smoking could be linked to schizophrenia and psychosis

You know that smoking is not good for you, but do you know exactly how? Most smokers do not really care to hear about the damaging effects of smoking, although they definitely should remember them. It is not just about an increased risk of lung cancer, yellow teeth, bad smell, […]

FDA Approves New Targeted Drug for Leukemia Tested at University of Pennsylvania

The U.S. Food and Drug Administration (FDA) has approved the first ever inhibitor drug specifically approved for treating patients with relapsed or refractory acute myeloid leukemia (AML) with a mutation in the Fms-like tyrosine kinase 3 (FLT3) gene. Patients with these mutations who have relapsed or refractory AML have very […]

It’s not a shock: Better bandage promotes powerful healing

A new, low-cost wound dressing developed by University of Wisconsin–Madison engineers could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient’s own body motions to apply gentle electrical pulses at the site of an injury. In rodent tests, the dressings reduced healing times […]

Five questions with Su-Chun Zhang, forger of brain cells

Su-Chun Zhang, a Waisman Center researcher and UW School of Medicine and Public Health professor of neurology and neuroscience, was the first in the world to craft human brain cells from human embryonic stem (ES) cells, and later from the related induced pluripotent (iPS) cells. In light of the 20th […]

Princeton and Microsoft collaborate to tackle fundamental challenges in microbiology

In this project, Microsoft is helping Princeton to better understand the mechanisms of biofilm formation by providing advanced technology that will greatly extend the type of research analysis capable today. Biofilms — surface-associated communities of bacteria — are the leading cause of microbial infection worldwide and kill as many people […]

Turning stem cells into bone with nanoclay-reinforced hydrogel

More than 50% of women and 20% of men over the age of 50 will experience a bone fracture during their lifetime. One way to prevent these fractures—particularly in the most sensitive parts of the skeleton—is delivery of stem cells by means of an injectable carrier, which safeguards the cells […]

Silent seizures: seeds of Alzheimer’s disease?

It can be frightening to watch a person experiencing an epileptic seizure. But some seizures can’t be seen, and these play a role in a different form of devastation—Alzheimer’s disease (AD)—according to work led by University of Minnesota researcher Keith Vossel. With colleagues at the University of California San Francisco […]

Enlarged heart linked to a higher risk of dementia

Left ventricular hypertrophy (LVH), also known as an enlarged heart, is associated with a nearly two times higher risk of dementia according to a recent University of Minnesota School of Public Health study published in the American Heart Journal. LVH is a condition in which the muscle wall of the heart's left pumping […]

UI study shows neighborhood conditions affect mortality, health outcomes

Does  where you live affect your health? Research has shown that neighborhoods with high socioeconomic deprivation also have higher mortality rates. But, those studies were a snapshot in time and did not consider how changes in socioeconomic deprivation—either positive or negative—corresponded to changes in health. Most research also didn’t track subjects over […]

‘Mini-placentas’ could provide a model for early pregnancy

Researchers say that new ‘mini-placentas’ – a cellular model of the early stages of the placenta – could provide a window into early pregnancy and help transform our understanding of reproductive disorders. Details of this new research were published in the journal Nature. Many pregnancies fail because the embryo does […]

Potential arthritis treatment prevents cartilage breakdown

Osteoarthritis, a disease that causes severe joint pain, affects more than 20 million people in the United States. Some drug treatments can help alleviate the pain, but there are no treatments that can reverse or slow the cartilage breakdown associated with the disease. In an advance that could improve the […]

A Lung Cancer Diagnosis and Treatment Revolution

Over the past 30 years, interventional cardiology has transformed heart care — replacing many interventions that used to require open-heart surgery with less invasive procedures. Today, that same revolution has arrived for pulmonary medicine with interventional pulmonology, or IP. The subspecialty offers a variety of minimally invasive procedures to diagnose […]
