COVID-19 may trigger hyperglycemia by disrupting key metabolic signals to cause severe disease

COVID-19 may bring high risks of severe disease and death in many patients by disrupting key metabolic signals and thereby triggering hyperglycemia, according to a new study from researchers at Weill Cornell Medicine and NewYork-Presbyterian.

Researchers find potential new target for treating systemic inflammation in obesity

A study led by researchers at the University of Chicago and Indiana University has determined that a protein called elF5A is necessary for driving inflammation in macrophage cells in obesity.

Immune cell betrayal makes aging mice less tolerant of cold temperatures

Human evolution has provided us a level of protection from the existential threat of cold temperature with the capacity to produce heat from fat stored in the body.

Study unravels widespread tumor suppression mechanism that halts cancer metastasis

According to a study by The Wistar Institute, the tumor suppressor Parkin, whose levels are reduced in different cancer types, causes acute metabolic and oxidative stress, suppresses mitochondrial trafficking, and blocks tumor cell movement, reducing primary and metastatic tumor growth.

Stress signal from fat cells could help protect the heart from obesity’s negative consequences

A stress signal received by the heart from fat could help protect against cardiac damage induced by obesity, a new study led by UT Southwestern researchers suggests.

Study reveals how high dietary fructose increases rates of obesity and cancers

Eating fructose appears to alter cells in the digestive tract in a way that enables it to take in more nutrients, according to a preclinical study from investigators at Weill Cornell Medicine and NewYork-Presbyterian.

Insulin resistance could be due to changes in specific subtype of fat cells, study suggests

It is well known that fat cells can influence our sensitivity to insulin. Now, researchers at Karolinska Institutet in Sweden have discovered that there are three different subtypes of mature fat cells in white adipose tissue and that it is only one of these, called AdipoPLIN, that responds to insulin.

Resistance exercise regulates fat cell metabolism at a molecular level, study finds

Findings from a new University of Kentucky College of Medicine and College of Health Sciences study add to growing evidence that resistance exercise has unique benefits for fat loss.

Research reveals a microRNA network as putative mediators of myocardial reductive stress

Last year, University of Alabama at Birmingham researchers reported that reductive stress - an imbalance in the normal oxidation/reduction homeostasis - caused pathological changes associated with heart failure in a mouse model.

UCLA professor honored for contributions to the field of hematology

Dr. Elizabeta Nemeth, professor of medicine and director of the Center for Iron Disorders at the David Geffen School of Medicine at UCLA, has been awarded the 2021 William Dameshek Prize by the American Society of Hematology (ASH) for her contributions to the field of hematology.

Lowering iron content in fat cells prevented mice from gaining excess weight

Lowering iron content in fat cells prevented mice fed a high-fat diet from gaining excess weight and developing associated health problems by limiting the amount of lipids absorbed by the intestines, UT Southwestern scientists report in a new study. The findings, published online in Cell Metabolism, could eventually lead to new strategies to protect people against obesity and related diseases.

New technique can measure metabolic process at the single-cell level

Understanding cellular metabolism - how a cell uses energy- could be key to treating a wide array of diseases, including vascular diseases and cancer.

Study finds molecular switch that controls the ability of organisms to adapt to low nutrient levels

Getting energy and nutrients from the environment - that is, eating - is such an important function that it has been regulated through sophisticated mechanisms over hundreds of millions of years. Some of these mechanisms are only now beginning to be unraveled.

Repressing a protein that facilitates DNA repair to potentiate chemotherapy

Chemotherapy kills tumor cells by causing damage to them. One of the most effective ways of causing damage is to prevent the two DNA strands from separating so that the cellular machinery cannot read the instructions written in the genes.

Study elucidates how Omega-3 fatty acids poison tumor cells

So-called "good fatty acids" are essential for human health and much sought after by those who try to eat healthily. Among the Omega-3 fatty acids, DHA or docosahexaenoic acid is crucial to brain function, vision and the regulation of inflammatory phenomena.

Discovery suggests new pathways for safeguarding the immune system’s ability to fight cancer

In order for cancer to grow and spread, it has to evade detection by our immune cells, particularly specialized "killer" T cells.

ONK Therapeutics and Trinity researchers seek to improve cellular therapies for treating cancer

ONK Therapeutics Ltd, an innovative natural killer (NK) cell therapy company, today announced that it has been awarded an Innovation Partnership Programme grant by Enterprise Ireland (EI) to fund collaborative research at Trinity College Dublin, Ireland, led by Dr. David Finlay to optimize the metabolism and engineering of NK cells for improved cancer therapies.

New chip mimicking bovine endometrium could play key role in cattle’s pregnancy success

To investigate factors that can jeopardize pregnancy success in cattle, researchers at the University of São Paulo (USP) in Brazil used a kind of chip to mimic the environment of the endometrium, the tissue that lines the inside of the uterus.

Study confirms the importance of low-protein, high-carbohydrate diet

Researchers at the University of Sydney's Charles Perkins Centre conducted the largest ever study of nutrient interactions by examining the health of mice on 33 different diets containing various combinations of protein to carbs, and different sources of carbohydrate.

Study explores therapeutic potential of exploiting autophagy cascade against COVID-19

Researchers recently reviewed current knowledge on links between autophagy and coronaviruses and how this knowledge can be used to repurpose autophagy modulators as potential treatment options for COVID-19. The review is published in the journal Frontiers in Microbiology.
