Activation of a single type of neuron appears to trigger hot-flash-like symptoms in mice.  In the issue of Cell Reports, researchers show that so-called Kiss1 neurons in the hypothalamus may be the link between sex hormone fluctuations and the hot flashes that affect many menopausal women. These cells project to a brain region controlling […]

The study, led by Imperial College London and researchers from the Universities of Bristol and Cambridge, also suggest pregnant women who develop high blood pressure (pre-eclampsia), or fetal growth restriction (where a baby's growth slows or stops before birth), may have differences in their blood circulation. The team tracked the […]

One of biology’s great mysteries is how a single fertilised egg can generate millions of cells that together make up a human body, while simultaneously restricting growth to prevent lethal diseases such as cancer. This process is strictly regulated by our DNA, the genetic cookbook carried by each single cell […]

Through x-ray crystallography and kinase-inhibitor specificity profiling, University of California San Diego School of Medicine researchers, in collaboration with researchers at Peking University and Zhejiang University, reveal that curcumin, a natural occurring chemical compound found in the spice turmeric, binds to the kinase enzyme dual-specificity tyrosine-regulated kinase 2 (DYRK2) at […]

A very low carbohydrate, high-fat diet called the ketogenic diet may improve the effectiveness of an emerging class of cancer drugs, according to a study in mice by investigators at Weill Cornell Medicine, Columbia University Irving Medical Center and NewYork-Presbyterian.

Growing miniature tumors from a patient’s cells in the laboratory may help scientists personalize treatments for those with a rare form of prostate cancer, according a study by Weill Cornell Medicine and NewYork-Presbyterian scientists. Patients with prostate cancer often receive therapies that reduce levels of testosterone. Many of their tumors […]

Young women with high body fat have a decreased chance of developing breast cancer before menopause, according to scientists at the National Institutes of Health and their collaborators.

A small-molecule drug is one of the first to preserve hearing in a mouse model of an inherited form of progressive human deafness, report investigators at the University of Iowa, Iowa City, and the National Institutes of Health’s National Institute on Deafness and Other Communication Disorders (NIDCD). The study, which […]

Gene therapy has gained momentum in the past year, following the federal government’s approval of the first such treatments for inherited retinal diseases and hard-to-treat leukemia. Now, research led by Washington University School of Medicine in St. Louis has shown, in mice, that genetic material can be delivered to damaged […]

UCLA-led team created a model to predict effectiveness of potential treatments to help the immune system. A research team led by a UCLA bioengineer has developed a model to predict the extent to which new laboratory-designed antibodies will be able to combat specific human diseases. This is the first time […]

Experiments using parasitic worms in the mouse gut have revealed a surprising new form of wound repair, a finding that could help scientists develop ways to enhance the body’s natural healing abilities. Researchers have long believed that adult stem cells contribute to wound healing in tissues like the gut and […]

Recent leaps in gene editing technology have brought ideas that just a decade ago seemed like science fiction to the cusp of reality. The already famous CRISPR system allows scientists to edit faulty genes by cutting and replacing sections of DNA, but new and improved CRISPR techniques have expanded CRISPR’s […]

Medicine is rapidly approaching a great advance that will augment or replace drugs with human cells for treating a range of intractable conditions, an expert in cell therapy told the Wisconsin Technology Council. Jacques Galipeau, assistant dean for therapeutics discovery at the University of Wisconsin School of Medicine and Public […]

This migration of cells can lead to metastatic disease, which causes about 90 percent of cancer deaths from solid tumors — masses of cells that grow in organs such as the breast, prostate or colon. Understanding the drivers of metastasis could lead to new treatments aimed at blocking the process […]

Eisai Co., Ltd. and Biogen Inc. (NASDAQ: BIIB) announced positive topline results from the Phase II study with BAN2401, an anti-amyloid beta protofibril antibody, in 856 patients with early Alzheimer's disease. The study achieved statistical significance on key predefined endpoints evaluating efficacy at 18 months on slowing progression in Alzheimer's […]

University of Adelaide research shows that the results of the most widely used test for prostate cancer may be affected by obesity. With increasing prevalence of obesity in high-income countries, this study published by the Society for Endocrinology, has important implications for detecting and monitoring the most common form of cancer […]

A device under development at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University could help bring back lost brain function by measuring how the brain responds to therapies that stimulate it with electric current. The approach could open new avenues for treating brain disorders and selectively switching […]

“By bringing together novel packaging and microelectronic technologies, and in close collaborations with ophthalmologists, we were able to design a miniaturized, fully wireless, and highly-sensitive sensor,” says Azita Emami, Caltech's Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering and a Heritage Medical Research Institute Investigator, and paper co-author.

Researchers at UW Medicine in Seattle have successfully used human stem cells to restore heart function in monkeys with heart failure. The findings suggest that the technique will be effective in patients with heart failure, the leading cause of death in the world. “The cells form new muscle that integrates […]

Can we use nanotechnology to transform our own immune cells into cancer serial killers? Dr. Carston R. Wagner, professor and endowed chair of the Department of Medicinal Chemistry in the College of Pharmacy and Masonic Cancer Center member, has proven so by his team’s development of techniques that activate immune cells, specifically T-cells, to […]

While out mowing his carefully kept lawn during the summer and fall of 2012, a 75-year-old retiree noticed his lower back and side didn’t feel quite right. But it didn’t seem like the normal muscle tweak and spasms. So, when he went in for his annual physical that fall, he […]

James McNew’s and Michael Stern’s biochemical hunt for the root cause of a rare, paralyzing genetic disorder is a 10-year quest that’s taken an unexpected turn toward everyday killers such as Alzheimer’s disease, cancer and aging.
