Inflammation-driven deterioration of structural proteins contributes to aging

Aging-related inflammation can drive the decline of a critical structural protein called lamin-B1, which contributes to diminished immune function in the thymus, according to research from Carnegie’s Sibiao Yue, Xiaobin Zheng, and Yixian Zheng published in Aging Cell. Each of our cells is undergirded by a protein-based cellular skeleton. And […]

Recovery twice as hard for survivors of childhood acute lymphoblastic leukemia

Nearly 90 per cent of children with acute lymphoblastic leukemia (ALL) survive, yet the same treatments that save their life can adversely affect their quality of life and cardiorespiratory fitness health.  In fact, the cardiorespiratory fitness of ALL survivors can be significantly worse than a sample of healthy Canadians, despite […]

Immune cells determine how fast certain tumors grow

Tumors arise when cells shake off their restraints and start to multiply out of control. But how fast a tumor grows does not depend solely on how quickly the cancer cells can divide, a new study has found. By examining brain tumors in mice, researchers at Washington University School of […]

Fish, Fruit, Healthy Fats: What Should Heart Disease Patients Eat?

Your heart procedure was a success, and cardiac rehabilitation is going strong. That, of course, is great news. But there’s more to do to keep your mind and body healthy in the long run, says Susan Ryskamp, a dietitian at the University of Michigan Frankel Cardiovascular Center. One key factor: food. […]

Self-healing DNA nanostructures

DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don’t persist long in biological environments because of enzymes called nucleases that degrade DNA. Now, researchers have designed DNA nanostructures that can heal themselves in serum. […]

Study reveals structure of a 'master switch' controlling cell division

Unregulated cell division is a hallmark of cancer, and one of the key proteins involved in controlling cell division is called FoxM1. Abnormal activation of FoxM1 is a common feature of cancer cells and is correlated with poor prognosis, metastasis, and resistance to chemotherapy. Now researchers at UC Santa Cruz […]

Interplay between mitochondria and the nucleus may have implications for changing cell’s ‘batteries’

Mitochondria, the ‘batteries’ that produce our energy, interact with the cell’s nucleus in subtle ways previously unseen in humans, according to research published in the journal Science. The study, led by scientists at the University of Cambridge, suggests that matching mitochondrial DNA to nuclear DNA could be important when selecting […]

Grünenthal Challenge: Cell-Based/Gene Therapies for Pain

Pain is an unpleasant sensation that is part of the body’s protective mechanism designed to give a warning of potential or actual tissue damage. When pain is not managed effectively, it can persist and become debilitating, resulting in an overwhelming burden of suffering and poor quality of life. Due to […]

New compounds could be used to treat autoimmune disorders

The immune system is programmed to rid the body of biological bad guys—like viruses and dangerous bacteria—but its precision isn’t guaranteed. In the tens of millions of Americans suffering from autoimmune diseases, the system mistakes normal cells for malicious invaders, prompting the body to engage in self-destructive behavior. This diverse […]

Study finds link between ambient ozone exposure, carotid wall thickness

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. It’s the first epidemiological study to provide evidence that ozone might advance subclinical arterial disease — injuries that occur to the artery walls prior to […]

Brain games? Yoga? What slows mild cognitive impairment?

As we age, many of us experience minor changes to memory, language and decision-making. These changes may represent mild cognitive impairment (MCI), an intermediate stage between age-related cognitive changes and the more serious condition of dementia. A number of behavioral interventions have shown promise to slow the advancement of MCI to dementia […]

Proteins on viral surface linked to formation of Alzheimer’s plaque

New research from Stockholm University and Karolinska Institutet shows that viruses interact with proteins in the biological fluids of their host which results in a layer of proteins on the viral surface. This coat of proteins makes the virus more infectious and facilitates the formation of plaques characteristic of neurodegenerative […]

A newly discovered mechanism reveals how Parkinson’s disease can spread

Tiny channels between nerve cells are involved in a newly discovered mechanism of how Parkinson’s disease can spread throughout the brain. Researchers from LiU demonstrate that harmful protein aggregates can “hitch a lift” with channel-forming proteins, and in this way spread to healthy cells. Neurodegenerative diseases, such as Alzheimer’s, Parkinson’s […]
