Combination breast cancer therapy targets both tumor cells and the blood vessels that supply them, MU researchers find

Each day, normal human cell tissues express a protein known as p53 that wages war against potential malignancies. However, between 30 and 40 percent of human breast cancers express a defective (mutant) form of p53 that helps cancer cells proliferate and grow. Now, researchers at the University of Missouri have found that […]

‘Molecular scissors’ could be key to cutting off diseases including HIV infection

One way to fight diseases including HIV infection and autoimmune disorders could involve changing how a naturally occurring enzyme called SAMHD1 works to influence the immune system, new research suggests. The study, led by researchers from The Ohio State University, details how the enzyme influences proteins that stimulate the immune […]

Monitor detects dangerously low white blood cell levels

One of the major side effects of chemotherapy is a sharp drop in white blood cells, which leaves patients vulnerable to dangerous infections. MIT researchers have now developed a portable device that could be used to monitor patients’ white blood cell levels at home, without taking blood samples. Such a device could […]

Even DNA that Doesn’t Encode Genes Can Drive Cancer

Most of the human genome — 98 percent — is made up of DNA but doesn’t actually encode genes, the recipes cells use to build proteins. The vast majority of genetic mutations associated with cancer occur in these non-coding regions of the genome, yet it’s unclear how they might influence […]

Better understanding ALS by looking at how cells change

It took eight long years of research, but now an international team led by neuroscientists at Université de Montréal has discovered a basic molecular mechanism that better helps understand how Lou Gehrig's disease, or amyotrophic lateral sclerosis (ALS), works. And that basic science could someday lead to new therapy for […]

Three-month course of chemotherapy as effective as six months following surgery for bowel cancer

Many patients receiving chemotherapy following surgery for bowel cancer may only need three months treatment rather than the six months currently given, new research published in Lancet Oncology has shown. An international clinical trial, funded by an NIHR and MRC partnership, has evaluated the effectiveness of a three-month course of adjuvant […]

A pill that staves off aging? It's on the horizon

Scientists have long known that restricting calories can fend off physiological signs of aging, with studies in fruit flies, roundworms, rodents and even people showing that chronically slashing intake by about a third can reap myriad health benefits and, in some cases, extend lifespan. From a public health perspective, that […]

Unraveling how stem cells from gum tissue accelerate wound healing

Ever notice how a cut inside the mouth heals much faster than a cut to the skin? Gum tissue repairs itself roughly twice as fast as skin and with reduced scar formation. One reason might be because of the characteristics of gingival mesenchymal stem cells, or GMSCs, which can give […]

Once-Mysterious ‘Atacama Skeleton’ Illuminates Genetics of Bone Disease

The skeleton, discovered in a leather pouch behind an abandoned church, was pristine: a tiny figure, just six inches long, with a cone-shaped head, 10 pairs of ribs, and bones that looked like those of an 8-year-old child. Found in the Atacama Desert of Chile and later affectionately nicknamed “Ata,” […]

Bones in All the Wrong Places

By the time he died in 1973, Harry Eastlack had two skeletons; the one he was born with, and the one that grew around it, gradually encasing him in a prison of his own bone. Forty-five years later, UConn researchers have shown in the journal Nature Communications that a certain type of […]

A combination of cancer immunotherapies could save more lives

Scientists at the University of Southampton have discovered a new combination of cancer immunotherapy treatment that could improve patients’ survival rates. The pre-clinical study, published in Clinical Cancer Research, by Dr Sarah Buchan and colleagues, combined antibodies targeting PD-1/PD-L1, a type of immunotherapy known as checkpoint blockade that overcomes the resistance […]

Stem Cells Treat Macular Degeneration

In July 2015, 86-year-old Douglas Waters developed severe age-related macular degeneration (AMD). He struggled to see things clearly, even when up close. A few months later, he became part of a clinical trial that used stem cell-derived ocular cells developed in part by researchers at UC Santa Barbara. His retinal […]

NIH-supported international team confirms new genetic mutation link to ALS

Kinesin family member 5A (KIF5A), a gene previously linked to two rare neurodegenerative disorders, has been definitively connected to amyotrophic lateral sclerosis (ALS) by an international team from several of the world’s top ALS research labs. The findings identify how mutations in KIF5A disrupt transport of key proteins up and […]

Memory Control

Harvard Medical School researchers based at Massachusetts General Hospital and the Harvard Stem Cell Institute have identified a neural circuit mechanism involved in preserving the specificity of memories. They also identified a genetic “switch” that can slow down memory generalization, the loss of specific details over time that occurs in both age-related […]

Rewinding the Clock

We are as old as our arteries, the adage goes, so could reversing the aging of blood vessels hold the key to restoring youthful vitality? The answer appears to be yes, at least in mice, according to a new study led by investigators at Harvard Medical School. The research, published […]

Immune cells in the retina can spontaneously regenerate

Immune cells called microglia can completely repopulate themselves in the retina after being nearly eliminated, according to a new study in mice from scientists at the National Eye Institute (NEI). The cells also re-establish their normal organization and function. The findings point to potential therapies for controlling inflammation and slowing […]

Hidden Variation

New research led by Harvard Medical School and Brigham and Women’s Hospital has unmasked hundreds of cancer-driving genes and revealed that different tissue types have shockingly variable sensitivities to those genes. The findings, published online in Cell promise to improve scientists’ understanding of normal and malignant cell proliferation. They also help explain […]

Expanding rings vital for viable embryos

Scientists have discovered a process during mammalian embryonic development that is critical for early embryos to develop into healthy blastocysts. Using advanced microscopy techniques and live mouse embryos, the researchers observed rings of actin – a main component of a cell’s cytoskeleton – forming on the surface of the embryo. […]
