Origin story: Rewriting human history through our DNA

For most of our evolutionary history — for most of the time anatomically modern humans have been on Earth — we’ve shared the planet with other species of humans. It’s only been in the last 30,000 years, the mere blink of an evolutionary eye, that modern humans have occupied the […]

When cells cycle fast, cancer gets a jumpstart

The progression of cancer has been studied extensively, and the key steps in this journey have been well mapped, at least in some solid tumors: Lesions to genes that confer risk of cancer accumulate and alter normal cell behaviors, giving rise, scientists believe, to early-stage cancer cells that eventually swamp […]

Skin Cancer Mystery Revealed in Yin and Yang Protein

It starts off small, just a skin blemish. The most common moles stay just that way — harmless clusters of skin cells called melanocytes, which give us pigment. In rare cases, what begins as a mole can turn into melanoma, the most serious type of human skin cancer because it […]

Blue mushroom dye used to develop new fluorescent tool for cell biologists

Reactive oxygen species (ROS), such as free radicals and peroxides, are produced in cells under oxidative stress. Whilst present in healthy cells in small amounts, excessive ROS in cells is damaging and can lead to cancer and neurodegenerative diseases such as Alzheimer’s Disease. The scientists at Bath, collaborating with researchers […]

Hydrogels control inflammation to help healing

Hydrogels for healing, synthesized from the molecules up by Rice University bioengineers, are a few steps closer to the clinic. Rice researchers and collaborators at Texas Heart Institute (THI) have established a baseline set of injectable hydrogels that promise to help heal wounds, deliver drugs and treat cancer. Critically, they’ve analyzed […]

‘Conductor’ Gene Found in Plant Root Stem Cell ‘Orchestra’

In a new paper, researchers at North Carolina State University lift the veil on the “conductor” plant root stem cell gene that helps orchestrate and coordinate stem cell division of different root stem cell types, ensuring the harmonic communication necessary for plant growth and maintenance. Ross Sozzani, an NC State associate […]

Treatment successfully delivers drug across the blood-brain barrier directly to brain tumor in mice

One of most potent drugs for treatment of glioblastoma, the most deadly type of brain tumor, can’t be used in patients because of two problems. First, it can’t reach its target because it’s blocked by the blood-brain barrier, a microscopic structure that protects the brain from toxins in the blood. […]

Stroke Drug Boosts Stem Cell Therapy for Spinal Cord Injury in Rats

Four months after treating them, Yasuhiro Shiga, MD, PhD, checked on his rats. Walking into the lab, he carried minimal expectations. Treating spinal cord injuries with stem cells had been tried by many people, many times before, with modest success at best. The endpoint he was specifically there to measure […]

Math Equation Predicts and Detects Liver Cancer

By combining RNA sequencing, bioinformatics and mathematical modeling, University of California San Diego School of Medicine and Moores Cancer Center researchers identified a sudden transcriptomic switch that turns healthy liver tissue cancerous. The finding was used to develop a quantitative analytical tool that assesses cancer risk in patients with chronic […]

Low genetic risk for ADHD may protect against negative life experiences

A recent study shows that people at low genetic risk for attention deficit hyperactivity disorder (ADHD) are not only less likely to have the disorder, they also have better than expected economic, health and behavioral outcomes in later life. The results, published in the journal Psychological Medicine, “capture far more than just […]

Turning to genetics to treat little hearts

A team of researchers at CHU Sainte-Justine and Université de Montréal has discovered a new mechanism involved in a common congenital disease of the aortic valve. The findings of the study, conducted in collaboration with the Hadassa Hebrew University Medical Center, were published in the prestigious journal Nature Genetics. Valve disease […]

Many psychiatric disorders originate from shared genes

The largest study of its kind so far shows that the eight most common psychiatric disorders have a common genetic structure. Researchers from iPSYCH and the Psychiatric Genomics Consortium are behind the new results, which could help to develop more precise diagnoses and improved treatment. Over the course of a […]

New model explains how our immune system sometimes helps cancer spread

Mathematicians at the University of Alberta have developed a model that explains how the immune system interacts with cancer—and in some cases, may help cancer spread to other areas of the body. “Past research has shown that sometimes, the immune system has the opposite effect of what we might expect,” […]

Asthma severity linked to microbiome of upper airway

A new study led by Washington University School of Medicine in St. Louis suggests there is a link between bacteria that live in the upper airway and the severity of asthma symptoms among children with mild to moderate asthma. The study raises the possibility that the airway’s microbiome could have […]

NIH launches first U.S. clinical trial of patient-derived stem cell therapy to replace dying cells in retina

Researchers at the National Eye Institute (NEI) are launching a clinical trial to test the safety of a novel patient-specific stem cell-based therapy to treat geographic atrophy, the advanced “dry” form of age-related macular degeneration (AMD), a leading cause of vision loss among people age 65 and older. The geographic […]

Researchers discover critical link to controlling inflammation in Crohn’s disease

Investigators at the Case Western Reserve University School of Medicine discovered that blocking interleukin-1α (IL1α), a protein that controls inflammation in the gut markedly decreases the severity of intestinal inflammation in a mouse model of Crohn’s disease (CD). The anti-inflammatory effects of the biological therapies used to neutralize IL1α were […]
