Raising Frogs Takes a Village: Accelerating Amphibian Research at the Marine Biological Laboratory

Sally Seraphin’s life in the research lab started with rats and roseate terns. Chimpanzees and rhesus macaques came next, then humans (and a brief foray into voles). When she pivoted to red-eyed tree frogs, Sally once again had to learn all kinds of new techniques. Suddenly, in addition to new sample prep and analysis techniques, she needed to get up to speed on amphibian care and husbandry. That led her to the Marine Biological Laboratory (MBL) in Woods Hole, MA.

“It’s a seaside resort atmosphere with experts in every technology you can imagine,” Sally says. “It’s a place to incubate and birth new approaches to answering questions.”

Sally spent the past two summers at MBL learning everything she needed to know about breeding and caring for amphibians. During that time, she also worked closely with Applications Scientists from Promega who helped her start extracting RNA from frog samples.

“The hands-on support from industry scientists is definitely unique to Promega and MBL,” she says. “It’s rare to have a specialist on hand who can help you learn, troubleshoot and optimize in such a finite amount of time.”

Adopting a New Model Organism

Sally studies how early stress impacts brain and behavior development. She hopes to deepen our understanding of how adverse childhood experiences connect to mental illness and bodily disease later in life. In the past, she studied how factors such as parental absence affected the neurotransmission of dopamine in primates. Recently, she changed her focus to developmental timing.  

“Girls who are exposed to early trauma like sexual or physical abuse will sometimes reach puberty earlier than girls who aren’t,” Sally explains. “And I noticed that there are many species that will alter their developmental timing in response to predators or social and ecological threats.”

The Power of Pyruvate, A Pivotal Player in Cellular Energy Metabolism

Today’s blog written by guest author Kendra Hanslik.

In the intricate dance of cellular processes that sustain life, pyruvate emerges as a central figure. It plays a crucial role in the energy production saga. This small molecule is the linchpin between glycolysis and the citric acid cycle, linking the breakdown of glucose to the production of adenosine triphosphate (ATP). In this article, we explore pyruvate’s origins, multifaceted roles, and its association with various diseases.

Transforming Forensic Science with DNA from Dust

In the evolving field of forensic science, a study by Fantinato et al. has opened new avenues in using DNA extraction and analysis to recover important information from crime scenes. Their work, “The Invisible Witness: Air and Dust as DNA Evidence of Human Occupancy in Indoor Premises,” focuses on extracting DNA from air and dust. This novel approach could revolutionize how crime scenes are investigated, especially in scenarios where traditional evidence—like fingerprints or bodily fluids—is scarce, degraded or has been removed from surfaces.

Macrophages: The Unsung Heroes of Immune Response and Biologic Drug Development 

When we think about the immune system, B cells and T cells are often the focus of attention. B cells are known for producing antibodies, and T cells are celebrated for their cytotoxic capabilities. More recently, however, macrophages are being brought into the spotlight and recognized for their integral role in immune defense and the field of biologic drug development.

Transformative Gene Therapies Greenlit for Sickle Cell Disease

In sickle cell anemia, red bloods cells elongate into an abnormal “sickled” shape

Sickle cell disease is a debilitating blood disorder that causes recurrent pain crises and severe health effects, and can drastically impact quality of life. Recently, Vertex Pharmaceuticals and CRISPR Therapeutics introduced Casgevy, or exa-cel, a novel form of gene therapy that could radically change the management of sickle cell disease. On the heels of exa-cel’s approval in Britain, this groundbreaking therapy was also recently approved in the U.S.

Coral, Ferrets and a Lot of Elephant Poop: 5 Years of the Revive & Restore Catalyst Science Fund

“We are expanding the toolkit available for conservation,” says Bridget Baumgartner, Director of Research and Development at Revive & Restore. “We’re a technology-focused organization with a network of technology experts – we’re here to help make researchers in this space as successful as possible.”

Bridget manages the Catalyst Science Fund for the non-profit Revive & Restore. This program has awarded more than 70 grants to researchers applying biotechnology tools in a unique way to support genetic rescue of endangered or extinct species. The fund was launched in 2018 with a $3 million pledge from Promega, and this year celebrated its fifth anniversary. In that time, projects supported by the Catalyst Science Fund have cloned a black footed ferret, developed methods for analyzing population genetics of isolated elephant herds, and much more.

“The donation from Promega enabled us to demonstrate that this long-term ‘Go Big or Go Home’ approach can create new capabilities that are going to be high-impact for wildlife conservation,” Bridget says.

Uniting Diverse Minds, Vibrant Ideas, and Collaborative Spirit at the 2023 Biologics Symposium

Biologics Symposium

On Thursday November 9th, 2023, Promega held its 7th Biologics Symposium at the Babraham Research Campus in Cambridge. For the first time, participants had the option to attend the event either in person or experience it via live stream, creating an inclusive and dynamic environment where the latest breakthroughs and ideas could be showcased. Moreover, the event was organized into a morning and afternoon session, enabling ample time for networking and the exchange of ideas beyond formal presentations.

Designing Science: A Behind-the-Scenes Look at Our Recent Journal Cover Art

A 3D illustration showing RAF inhibitor LXH254 engages BRAF or CRAF protomers (orange), but spares ARAF (red). Unoccupied ARAF is competent to trigger downstream mitogenic signaling, which is demonstrated with lightning bolts. Red cells in the background are fluorescently labeled RAS proteins, expressed in live cells. The Cell Chemical Biology cover type superimposes the image.

We made the cover! Of Cell Chemical Biology, that is.

This July, Cell Chemical Biology editors accepted a study from Promega scientists and invited the research team to submit cover art for the issue. The study in question details a BRET-based method to quantify drug-target occupancy within RAF-KRAS complexes in live cells. Promega scientists Matt Robers and Jim Vasta collaborated with one of our talented designers, Michael Stormberg, to craft an image that accurately represents the science in a dynamic and engaging way.

You can check out the paper and cover art in the November 16 issue of Cell Chemical Biology.

I spoke with Michael Stormberg to learn more about the creative process that went into creating this cover art and how he worked with the research team and other collaborators.

Myths, Misconceptions and Debated Theories in Biology

Research studies and novel discoveries continually reshape our understanding of the natural world, often refining—and sometimes contesting—prevailing scientific theories. While this influx of new information is important for expanding knowledge, it can also give rise to myths and misconceptions stemming from biases, media misrepresentations and overgeneralizations. In this blog, we’ll explore misconceptions that blur the lines between fact and fiction, some scientific myths that just won’t go die and theories that scientists can’t stop debating.

Humans Only Use 10% of Their Brain 

This myth, frequently perpetuated through movies like Lucy with Scarlett Johansson and Limitless with Bradely Cooper, has ambiguous roots. Some attribute this pseudoscience to Albert Einstein, despite no recorded record of such a claim, while others associate it with a misinterpretation of William James and his “Reserve Energy Theory” (8).
