A Live-Cell NanoBRET Assay Shines Light on Toxic RNA–Protein Interactions in Myotonic Dystrophy

Posted on by Johanna Lee
How NanoBRET works image.

RNA doesn’t just carry genetic instructions—it also interacts with proteins to regulate nearly every aspect of gene expression, from splicing to translation. When those interactions go awry, the consequences can be devastating. In myotonic dystrophy type 1 (DM1), the most common adult-onset muscular dystrophy, a toxic RNA repeat expansion hijacks a critical protein called MBNL1, trapping it in nuclear clumps called foci. This leads to widespread splicing defects and progressive muscle wasting. But studying these toxic interactions inside living cells—and finding small molecules that can disrupt them—has been a significant challenge.

A recent study led by the Scripps Institute may have a solution. The study introduces a NanoBRET™ assay that can monitor the interaction between the expanded CUG RNA repeats and MBNL1 protein in real time, in live cells. Their findings demonstrate how this platform can be used not only to detect disease-driving RNA–protein complexes but also to identify small molecules that break them apart.

From Gum Disease to Breast Cancer: An Oral Bacterium’s Unexpected Journey

Posted on by Sara Millevolte

You’re sitting in the dentist’s chair, nodding along to the familiar flossing lecture you’ve been politely ignoring for most of your adult life. Fair enough. It’s hard to get excited about gum health. But it turns out your dentist may have been underselling the pitch.

A study published in January 2026 in Cell Communication and Signaling shows that a common gum disease bacterium can promote breast cancer growth and spread in mice, and the findings hint at a particularly troubling link for people carrying BRCA1 mutations (1). “Floss to help prevent cancer” probably wasn’t on your 2026 bingo card, yet here we are.

Life on Mars? Proteomic Secrets of Bacterial Survival in Martian Brines

Posted on by Sara Millevolte

Could bacteria survive on Mars? While images of the red planet might spark thoughts of barren landscapes and lifeless deserts, Mars holds a fascinating possibility: under suitable conditions, pockets of salty, perchlorate-rich brines could temporarily form on or near its surface. These brines are formed by salts that naturally absorb water from their surroundings. By lowering the temperature at which water freezes, these salts can stabilize liquid water, raising intriguing questions about the potential for microbial life. But what exactly would it take for bacteria to survive there? New research from Kloss et al. published in Scientific Reports sheds light on this cosmic question.

Promega Fc Effector Assays: Measure Every Mechanism

Posted on by Promega

This post is written by Kai Hillman, PhD, Promega Corporation.

Every day, scientists push the boundaries of what’s possible with monoclonal antibodies (mAbs)—from targeting cancer cells to calming autoimmune-driven inflammation. These therapies rely not only on binding but on engineering the desired immune response. The suite of Promega Fc Effector Assays helps you understand these interactions from receptor binding and function, through bridging studies. With consistency, sensitivity, and scalability, these assays support teams from early discovery through lot release.

This article draws on real-world publications and product insights to show how Promega assays are powering next-generation immunotherapies—and redefining how we measure immune engagement.

What Shelter Dogs Can Tell Us About Emerging Zoonotic Diseases

Posted on by Michele Arduengo, PhD

Why Are Zoonotic Diseases Becoming a Bigger Risk?

As of September 9, 2025, the Worldometer listed the human global population as 8.3 billion people (1). This population growth means that humans will be living and working in previously uninhabited or minimally disturbed environments, increasing interactions between humans, domestic animals, wildlife, and their pathogens. This intensifying human-animal interface heightens the risk of zoonotic disease transmission, where pathogens cross species barriers (from wildlife to domestic livestock or from wildlife to humans), potentially leading to outbreaks and even pandemics.

How Do Urbanization and Climate Change Amplify Zoonotic Threats?

Urbanization, habitat disruption, and climate change further exacerbate these risks by altering ecosystems and facilitating the spread and emergence of vector-borne and zoonotic diseases. Understanding and addressing these threats requires robust surveillance, effective diagnostics, and proactive strategies to prevent and mitigate disease emergence and spread.

In urban areas, public health officials are already using wastewater to monitor known pathogens and identify “hot spots” of activity to predict increases in illness within local populations (2). Animal shelters are another place where there is an opportunity to monitor for emerging infectious diseases that could affect domestic pet animals.

Polyserine Targeting: A New Strategy Against Neurodegeneration

Posted on by Johanna Lee

Neurodegenerative diseases like Alzheimer’s are marked by the accumulation of misfolded proteins that wreak havoc on neurons. One of the most notorious culprits is tau, a structural protein that, in its diseased form, clumps together into aggregates that spread throughout the brain. These aggregates interfere with normal cellular processes, leading to memory loss, behavioral changes, and other devastating symptoms. Preventing tau aggregation is therefore a key strategy for slowing the progression of these symptoms.

What if we could recruit molecular “helpers” to stop tau from accumulating?

Developing an Experimental Model System to Understand the Tumor Microenvironment of Melanoma Brain Metastases

Posted on by Michele Arduengo, PhD

Cancer’s greatest threat is its ability to spread to other tissues—a process known as metastasis. Melanoma, a form of skin cancer, exemplifies this devastating progression. Although treatable when caught early—with surgical removal resulting in over 99% survival at five years—once melanoma metastasizes, five-year survival rates plummet dramatically to around 27%. Even more concerning, melanoma exhibits a particularly high tendency to invade the central nervous system, causing melanoma brain metastases (MBMs) that are incurable and reduce median survival to just 13 months.

To understand metastasis, we need reliable and realistic experimental models. Traditional cell cultures on plastic dishes are limited, failing to replicate the intricate spatial organization and biochemical interactions within living tissues. Animal models are informative but expensive, ethically complex, and not always accurate for human diseases. Addressing this critical gap, Reed-McBain and colleagues (2025) introduced an innovative microphysiological system (MPS) designed to simulate the tumor microenvironment in the brain affected by metastatic melanoma.

How Computational Design Can Predict the Next Viral Variant—and Help Us Prepare

Posted on by Johanna Lee

As SARS-CoV-2 continues to evolve, one lesson is painfully clear: immunity today may not guarantee protection tomorrow. Viruses are experts at mutating into countless variants to evade detection or neutralization by the immune system. In the race to keep up with this “immune escape”, researchers have largely focused on reactive strategies—testing vaccines against variants that already exist. But what if we could flip the script and anticipate where the virus is going next?

That’s precisely the aim of a new study published in Immunity. This study introduces EVE-Vax, a computational design platform that builds synthetic spike proteins capable of mimicking immune escape mutations—before they naturally arise.

IL-6/STAT3-Regulated Long Non-Coding RNA Is Involved in Colorectal Cancer Progression

Posted on by Michele Arduengo, PhD

Researchers from Wenzhou Medical University in China have identified a mechanism involving long non-coding RNAs (lncRNA) that contributes to colorectal cancer (CRC) progression. CRC is the third most common cancer worldwide and is one of the most lethal cancers across the globe. Understanding the molecular mechanisms that underlie the development and progression of CRC is critical to developing biomarkers to detect it and new therapeutics to treat it.

What’s Hiding in Your Mussels?

Fresh mussels might be a delicacy in many parts of the world, but a new study from Italy suggests they could also be carriers of something much less appetizing: infectious viruses and antibiotic resistance genes (ARGs). Published in Food and Environmental Virology, Venuti et al. (2025) investigated 60 mussel batches originating from the Campania (Southern Italy), Lazio and Puglia regions—and what they found raises important questions about food safety and environmental monitoring.
