New Drug-Like Molecule Enhances Mitophagy, Protects Against Neurodegeneration

Having healthy mitochondria, the organelles that produce energy in all our cells, usually portends a long healthy life whether in humans or in C. elegans, a tiny, short-lived nematode worm often used to study the aging process.

Study Links Adenovirus Infection With a Rare Blood Clotting Disorder

Platelets, or thrombocytes, are specialized cellular fragments that form blood clots when we get scrapes and traumatic injuries. Viral infections, autoimmune disease, and other conditions can cause platelet levels to drop throughout the body, termed thrombocytopenia.

How Do Humans Maintain a Healthy Blood Sugar Level After Meals?

A study of more than 55,000 people’s DNA from around the world has given insight into how humans maintain appropriate blood sugar levels after eating, with implications for the current understanding of how the process goes awry in type 2 diabetes.

New Toolbox Assists in the Understanding of Intricate Genetic Traits

Elizabeth King, Associate Professor in the Division of Biological Sciences at the University of Missouri, was inspired to spend her formative years studying science by a lifelong curiosity about the natural world and the diversity of life—and along the way, she discovered her passion for biology.

New Genes Associated With SCAD Identified

The National Institute for Health and Care Research (NIHR) Leicester Biomedical Research Centre (BRC) and Universite Paris Cite have identified new genes linked with an increased incidence of a type of heart attack that primarily affects young to middle-aged women, with support from global partners in Canada, the United States, and Australia.

Using Cellular Reprogramming to Make the Heart Function Like New Again

A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and recreate cardiac muscle, allowing the heart to function like new again.

Endothelial Deletion of Wt1 Gene During Coronary Vessel Formation Affects Embryonic Heart Development

How is the mammals' heart formed? What role do endothelial cells play? Do the same pathways and genes involved in the formation of the embryonic heart also play a role in repair processes?

Single mechanosensitive protein shown to contribute to fibrosis in multiple organs

Researchers from Kyushu University have found how a single mechanosensitive protein induces the process that thickens and scars tissue, known as fibrosis. The protein, called VGLL3, was shown to contribute to fibrosis in multiple organs.

Study suggests new strategy for treating arrhythmogenic cardiomyopathy

University of Utah Health scientists have corrected abnormal heart rhythms in mice by restoring healthy levels of a protein that heart cells need to establish connections with one another.

Scientists reveal mechanisms behind oxygen toxicity

When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs. Until now, however, scientists have mostly speculated about the mechanisms behind this phenomenon, known as oxygen toxicity, or hyperoxia.

Cell therapy trial promises long-term improvement for patients with chronic heart failure

Physician-scientists at The Texas Heart Institute announced today the results of the largest cell therapy trial to date in patients with chronic heart failure due to low ejection fraction.

Experts develop new single-cell “chromatin atlas” of the human genome

Researchers from the University of Virginia School of Medicine have developed a crucial new tool that provides a better understanding of how genes in particular cells affect the risk of developing heart disease, the world’s leading cause of death.

Cell-derived therapy may help treat ventricular arrhythmia

Vesicles secreted from human heart cells may repair damaged tissue and prevent lethal heart rhythm disorders, according to a new study from investigators in the Smidt Heart Institute at Cedars-Sinai.

Breakthrough discovery provides a desirable drug target to tackle metabolic diseases

In a breakthrough discovery, scientists from The University of Texas Health Science Center at San Antonio today reported that inhibiting a liver enzyme in obese mice decreased the rodents' appetite, increased energy expenditure in adipose (fat) tissues and resulted in weight loss.

Genetic risk score may help identify Type 2 diabetes patients with a higher risk for cardiovascular events

A risk score based on a gene map predicted the likelihood of high blood pressure leading to heart problems or stroke in people with Type 2 diabetes, according to a study published today in the American Heart Association's peer-reviewed journal Hypertension.
