It’s about time. Nobel Prize honors pioneers in circadian clock biology

By Kevin Moore

Like gravity, some phenomena are so integral to our existence that we’re barely conscious of them. Maybe that’s why the research community was largely taken by surprise when it was announced that this year’s Nobel Prize in Physiology or Medicine was awarded to three American scientists for their seminal work on circadian clocks ¹. But consider the synergies with next gen sequencing (NGS) and gene editing technologies, and it becomes clear that the implications of their work are far-reaching.

The choice is clear: saliva vs. blood diagnostics for hormone testing

By Magali Fischer

Diagnostic testing has a long, bloody (i.e., blood-based) history, and when a physician orders a test, the usual response is to strap on a tourniquet, pull out a syringe, and extract a venous blood sample. For some tests, though, and, especially to measure levels of steroid hormones such as estrogen, testosterone, or cortisol, a blood sample might not be the best choice.

Diagnostic saliva hormone testing

By Magali Fischer

Steroid analysis using a saliva sample first appeared in the scientific literature more than 40 years ago.1 Now, as then, saliva sampling presents an attractive alternative to blood testing because it is non-invasive, easily repeatable, can be performed in settings that may not be conducive to blood sampling, and is less stressful and more convenient for patients.

The gold standard ELISA for measuring HMGB1

By Oliver Schmidt

HMGB1 is a key mediator in the immune response and increased levels can be important indicators of disease. In this, the last in our series on HMGB1, we will look at the performance of the IBL HMGB1 ELISA Kit, which has been used to demonstrate the value of total HMGB1 as a clinical biomarker in a wide range of sample types and diseases. This kit is regarded by key opinion leaders as the gold standard in the field and has been used in more than 800 publications.

How to measure alarmin HMGB1

By Oliver Schmidt

In the first article in this series, we looked at how HMGB1 has taken an increasingly important position as a key mediator in the immune response and as such plays a major role in a large number of diseases – from sepsis to cancer. As Professor Helena Erlandsson Harris, a pioneer in HMGB1 research, says, “I am convinced that the next step will be even better data to demonstrate the usefulness of HMGB1 as a prognostic/diagnostic biomarker. This has been hampered by the need to understand the isoforms that control different functions and also the methods for measuring HMGB1. It would be even better if HMGB1 detection were included in larger biomarker panels.” HMGB1 has indeed been included as a necessary biomarker in consensus guidelines for the detection of immunogenic cell death. The question is how to measure it. In this article, we will look at the development of increasingly sensitive, reliable and easy-to-use assays for clinical research and routine use and how this has been complicated by the need to resolve the isoforms, and also overcome interference caused by auto-antibodies and other proteins that naturally interact with HMGB1 to modulate its function.

What the alarmin HMGB1 teaches us about cellular stress response

By Oliver Schmidt

As a nuclear protein present in most cell types, HMGB1 (high mobility group box 1) is a key mediator of the immune system in health and disease. Interest in HMGB1 has increased dramatically as the protein has been shown to be critical to the cell’s response to stress and plays a major role in many disease states, including infectious diseases, ischemia, immune disorders, neurodegenerative diseases, metabolic disorders, and, not least, cancer. Highly conserved in mammals, HMGB1 (also known as HMG-1 and amphoterin) is primarily located in the chromatin where it stabilizes chromosome structure and plays a key role in controlling gene expression.

The heart of the matter: finding the 99th percentile for high-sensitivity troponin assays

By Alexandra Sommer

Cardiovascular diseases claim more lives than all forms of cancer combined, accounting for 17.3 million deaths per year. Heart attacks are a primary symptom. The longer it takes to diagnose and treat a heart attack, the greater the damage. But progress in identifying relevant cardiac enzymes and other biomarkers has increased the likelihood of rapid and accurate diagnosis to ensure effective treatment and improve long-term survival. Several cardiac markers have been developed for the rapid diagnosis of patients with chest pain and suspected acute coronary syndrome. One of these markers, cardiac troponin, stands out and the ability to better define troponin levels is expected to help diagnose heart attacks more effectively, and even predict them.

Oncology prognostics: Why analyzing circulating cell free tumor DNA matters

By Nicholas Smith

We may well be on the threshold of a new hope for oncology. Shorthanded to ctDNA, circulating cell free tumor DNA is sloughed off from tumors. It can be detected in liquid biopsies of just a few milliliters of blood. This could revolutionize what oncology can achieve by diagnosing cancers earlier and more efficiently.
