Hyperpolarized MRI enables real-time view on metabolic processes
Hyperpolarized MRI is a recent development and its research and application potential has yet to be fully explored. Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have now unveiled a new technique for observing metabolic processes in the body. Their singlet-contrast MRI method employs easily-produced parahydrogen to track biochemical processes in…

Hyperpolarised MRI boosts cancer diagnosis
Tumour metabolism can be imaged with MRI as a technique to help determine cancer aggressiveness and response to therapy. The work by a UK-based group, on probing cancer metabolism non-invasively with clinical hyperpolarised carbon-13 MRI, can detect metabolic changes in the tumour. As metabolic changes occur much earlier than change in tumour size, this could have implications for quicker…

Food for thought: How our brain keeps its supply up
Our brains are non-stop consumers. A labyrinth of blood vessels, stacked end-to-end comparable in length to the distance from San Diego to Berkeley, ensures a continuous flow of oxygen and sugar to keep our brains functioning at peak levels. But how does this intricate system ensure that more active parts of the brain receive enough nourishment versus less demanding areas? That’s a century-old…

Mutations help bacteria resist antibiotic treatment
Bacteria have many ways to evade the antibiotics that we use against them. Each year, at least 2.8 million people in the United States develop an antibiotic-resistant infection, and more than 35,000 people die from such infections, according to the U.S. Centers for Disease Control. Most of the mutations known to confer resistance occur in the genes targeted by a particular antibiotic. Other…

A new technique to understand metabolic pathways
Mass spectrometry-based metabolomics has emerged as a powerful tool to help study chemical ecology. Recent advances in the technique make it possible to study microbial interactions from complex communities. Laia Castaño-Espriu outlined the role and benefits of MS in this context in her presentation ‘Analysis of microbial ecology by mass spectrometry-based metabolomics techniques’, at the…

Sugar consumption: a driving factor in onset of pancreatic cancer
A diet high in sugar increases the likelihood of developing pancreatic cancer in some people and can also drive the aggressive growth of tumours, a new study finds. During this study, researchers from the University of Surrey, VIB-KU Leuven, Belgium and the Babraham Institute in Cambridge, sought to understand the impact of diet on the development and progression of pancreatic cancer. This rare…

Disrupting cellular pH balance blocks pancreatic cancer
Scientists at Sanford Burnham Prebys have found a new way to kill pancreatic cancer cells by disrupting their pH equilibrium. The study, published in Cancer Discovery, reports how depleting an ion transport protein lowers the pH to a point that compromises pancreatic cancer cell growth. Pancreatic cancer cells—like all cancer cells—have a constant need for energy to support their growth and…

The uncanny influence of our gut flora
Scientists from the German Cancer Research Center (DKFZ) and the Hebrew University in Jerusalem demonstrated in mice that intestinal bacteria reprogram DNA activity in cells of the gut mucosa and thus have a considerable impact on the development of the healthy gut.

Celiac disease: 'Reprogramming' the immune system to tolerate gluten
Celiac disease affects 0.3-2.4% of people in most countries world-wide, and approx. 2% in Finland. Celiac patients suffer from a variety of symptoms, typically intestinal complaints, such as diarrhea, but are often symptom-free. Immunologist Tobias Freitag co-developed and tested nanoparticles containing gliadin for the immunomodulatory treatment of celiac disease in Professor Seppo Meri’s…

Gut flora could hold the key for new diabetes treatments
An organic compound produced by the gut flora – the metabolite 4-Cresol – is considered to have protective effects against both type 1 and 2 diabetes, notably by stimulating the growth of the insulin-producing pancreatic beta cells. This is according to a new study led by Inserm researcher Dominique Gauguier at the Environmental Toxicology, Therapeutic Targets, Cell Signaling and Biomarkers…

Ferroptosis could be key for new anticancer approach
A team of researchers lead by Helmholtz Zentrum München and the University of Würzburg identified an enzyme as a novel and strong inhibitor of ferroptosis, the iron dependent form of cell death: ferroptosis suppressor protein-1, short FSP1. This protein is expressed in a variety of cancer cell lines and therefore represents an attractive drug target for cancer treatment.

Why fatty livers are more susceptible to cancer
Fatty liver disease is contributing to an increase in liver cancer and basic scientists at The University of Texas Health Science at Houston (UTHealth) have new insight as to why. In the journal Cancer Research, the investigators report that in mouse models, excess fat impairs the ability of a tumor-suppressing protein named HNF4α to do its job. “This study provides potential mechanisms for…

Red and processed meat: not so bad for our health, but...
Most people can continue to eat red and processed meat as they do now. A major study led by researchers at McMaster and Dalhousie universities has found cutting back has little impact on health. A panel of international scientists systematically reviewed the evidence and have recommended that most adults should continue to eat their current levels of red and processed meat. The researchers…

A recent study led by Assistant Professor Feng Lei from the National University of Singapore (NUS) Yong Loo Lin School of Medicine’s Department of Psychological Medicine revealed that regular tea drinkers have better organised brain regions – and this is associated with healthy cognitive function – compared to non-tea drinkers. The research team made this discovery after examining…

Multiple Sclerosis: Do zinc and iron play a role?
Some studies have suggested that minerals such as zinc and iron may play a role in how multiple sclerosis (MS) progresses, once people have been diagnosed with it. But little was known about whether zinc, iron and other minerals play a role in the development of the disease. A new study shows no link between dietary intake of several minerals and whether people later develop MS. The study is…
