absolute gene-ius by Jordan Ruggieri, Christina Bouwens

In this episode, Michael Stump and Matteo Franco from ProtaGene explore the growing importance of integration site analysis (ISA) in cell and gene therapy. As viral vectors like lentivirus and AAV become more widely used, understanding where and how they integrate into the genome is essential for assessing genotoxicity and long-term safety. The discussion dives into how sequencing reveals integration locations, clonal expansion risks, and potential activation of oncogenes. They also highlight how tools like digital PCR complement sequencing as orthogonal methods that help enable precise quantification, validation, and new applications like vector integrity and copy number analysis. Beyond the science, the conversation explores the CRO role in supporting both early-phase discovery and late-stage regulatory needs, balancing innovation with regulatory expectations, and adapting to emerging modalities like LNPs.

PCR may be decades old, but it is still one of the most versatile tools in modern molecular biology.

Dr. Robert Philibert joins the show to unpack the fascinating world of epigenetics, where environmental factors like smoking, alcohol, and lifestyle reshape how genes are expressed. He explains how methylation, histone modifications, and chromatin structure act as regulatory layers on top of DNA, influencing disease risk far more than previously thought. The conversation dives into how technologies like bisulfite conversion and digital PCR enable precise measurement of these changes, transforming epigenetic signals into actionable data. Dr. Philibert also highlights real-world applications, from detecting behavioral risk factors to enabling early disease biomarkers, emphasizing how epigenetics can’t be “gamed” like traditional reporting methods, making it a powerful tool for precision health interventions.

Multiplexing is reshaping how scientists think about PCR experiments, turning single-target workflows into powerful, multi-dimensional analyses.

In this episode, Fiona Connolly, former Platform Innovation and Automation Scientist at bit.bio, explains how deterministic programming replaces the traditional “pinball machine” model of stem cell differentiation with precise genetic instructions. By identifying the exact transcription factor combinations, the “cheat codes” that define specific cell fates, Fiona’s team engineers induced pluripotent stem cells (iPSCs) to reliably become neurons, oligodendrocyte-like cells, and other specialized types. She discusses how digital PCR enables accurate transgene copy number validation and multiplexed screening of hundreds of clones, while RNA-seq and qPCR confirm expression fingerprints. The result? Consistent, scalable, high-quality human cell models that accelerate disease research, particularly in areas like neurodegeneration and multiple sclerosis while reducing reliance on animal models.

Science doesn’t just advance through breakthroughs, it advances through mistakes. This Science Snapshot episode embraces a universal truth of research: if you haven’t messed something up in the lab, you probably haven’t been there very long. From chemical reactions gone wrong to experiments derailed by one small oversight, these stories are as relatable as they are unforgettable. 

Viruses are not always something to fear; they can also be tools to heal. This episode looks into this positive side of viral biology.

In this episode of Absolute Gene-ius, the hosts dive into the evolving world of precision oncology, where detecting rare molecular signals can make all the difference.

PCR inhibitors are everywhere and they can definitely mess with your data. From muddy lake water to complex viral vector preparations, inhibition is a reality that can’t be ignored.

What do vineyards, airborne spores, and digital PCR have in common? Turns out – quite a lot. This episode kicks off Season 4 by going green with plant pathology and molecular diagnostics. 

We’re back and better than ever. Season 4 of Absolute Gene-ius is officially here, and this teaser gives you a front-row seat to what’s coming. From scientific puns to sneak peeks of the upcoming guest lineup, co-hosts Jordan Ruggieri and new addition Lisa Crawford set the tone for another season of engaging, educational, and entertaining molecular biology content.

HIV, superbugs, and standards—oh my! In this episode of Absolute Gene-ius, we explore the frontier of infectious disease research with Dr. Jesús Mingorance, researcher at Hospital Universitario La Paz in Madrid. His research is translational and uses digital PCR, qPCR, sequencing, and more.

Can you detect Alzheimer’s with a spit sample? That’s the question driving Arianna Arbona’s exciting research at Universidad Pablo de Olavide in Sevilla, Spain. In this episode of Absolute Gene-ius, she shares how she’s isolating microvesicles from saliva and blood to identify early biomarkers for neurodegenerative diseases like Alzheimer’s—an effort that could one day lead to minimally invasive diagnostic tools.

This episode of Absolute Gene-ius slithers into the surprising science of invasive species monitoring with Dr. Brian Bahder. A childhood love of bugs led Brian to a dynamic career in entomology and plant pathology—and eventually to tracking large reptiles in the swamps of Florida.

Ever thought about why medications work differently for different people? In this episode of Absolute Gene-ius, we explore the exciting field of pharmacogenomics with Wendy Wang, pharmacogenetic laboratory supervisor at Children's Mercy Hospital in Kansas City. Wendy shares how genetics can influence drug metabolism, offering a glimpse into how precision medicine can revolutionize healthcare by tailoring treatments based on an individual's unique genetic makeup.

Scientific discovery happens in the lab—but it starts with curiosity and determination. In this episode of Absolute Gene-ius, we welcome Valeria Rangel, a PhD candidate at the University of California Irvine, who shares her research on acute lymphoblastic leukemia and the innovative ways digital PCR is helping uncover genetic patterns linked to cancer in Hispanic populations.

In this episode of Absolute Gene-ius, Dr. C. Dustin Rubinstein takes us inside the world of advanced genome editing, where cutting-edge tools like CRISPR and digital PCR are helping shape the future of biomedical research.

Season 2 of Absolute Gene-ius comes to a close with a look back at the topics and inspiring conversations that have defined the series. From exploring innovative uses of digital PCR to uncovering its synergy with other molecular tools, this season was packed with insights for scientists at all levels.

The statistics of Poisson distributions can seem complex at first but are simpler than you think, which is important to know given their relevance to digital PCR. In short, they dictate the confidence you can have in the absolute quantification provided by dPCR. 

Same may think of the pathologist’s toolbox as only the microscope and their eyes, but in reality today’s pathologists are using more and more molecular methods like NGS and PCR in additional to their traditional tools. 

Modern science, especially in the genetic and molecular biology spaces, generate vast amounts of data, and require vast amounts of data to be generated for thorough analysis. For example, finding a rare gene mutation such as BCR-ABL as a biomarker for chronic myeloid leukemia is like searching for a needle in a haystack. For a situation like this, dPCR is an ideal method, but high-throughput automation is also needed.

The potential of mRNA medicines was postulated for years, but it took the COVID pandemic and emergency use authorizations for that potential to be demonstrated. By now, most of us have received at least one mRNA based vaccine and the platform has been mostly derisked. However, if you’re not one of the major players in this space, generating high-purity mRNA, let alone a GMP-grade mRNA-based drug product, can still be quite challenging. 

Viral vectors are a cornerstone of gene therapy and many employ experts in the viral vector services space to help design and produce their specialty vectors. These service providers are experts at making sure you get the vector you want with a titer and purity you need for your application. 

When you have a good thing going you often want it to last forever, but we know that can never happen. Life and the world around us are fluid, dynamic, and we’re always finding the balance of fighting or harnessing entropy and inevitable change.

The fields of Cell and gene therapy are booming and poised to change the treatment and prevention of disease. These research areas require the transfer of genetic material to cells, and viral vectors are commonly used here. Specifically, adeno-associated virus (AAV) and lentiviral vectors (LVV) are vectors of choice. 

Organ transplantation is a modern marvel, with more than 157,000 solid organ, and more than 9,000 marrow and blood transplants occurring worldwide in 2022. Organ donor and recipient matching and compatibility screening has progressed significantly in recent decades as molecular methods have progressed rapidly to support this and other fields. Specifically, typing of human leukocyte antigens (HLAs) has expanded to consider ethnic population variation and cell free DNA (cfDNA) monitoring is now being used to monitor recipients for biomarkers that indicate organ rejection.  

Before the 1990s, small bits of RNA were considered junk by most, but the 1993 discovery of microRNA (miRNAs) began to reveal that bits of only 19-24 nucleotides of RNA can have an important gene regulation function in cells. Since their discovery, there has been a flurry of work to catalog known miRNAs and understand their functions, which include being tied to specific disease states such as leukemia. 

Designing a successful PCR assay is all about selecting the right primers to deliver the sensitivity and selectivity for which PCR is known for. But anyone that’s designed an assay themselves will know that doing so successfully is a lot harder it sounds. 

Blood is a symbol of life, which makes sense given that it plays such an important role in so many body functions, including our immune system. Blood makes up approximately 8% of your normal body weight and unfortunately, cancers of the blood, including lymphoma and leukemia, account for ~10% of all diagnosed cancers in the U.S. each year.  

We are all the product of a reproductive process, yet reproductive biology, or the study of the processes and mechanisms involved in reproduction, is not well understood. Deepening our understanding of reproductive biology is crucial to advancing assistive reproductive technologies (ART) and advancing our collective comprehension of inheritance and evolution. 

Welcome back Gene-iuses!  Jordan and Cassie kick us off with a fun teaser of what’s to come in Season 2 of the Absolute Gene-ius series.  

It’s not every day that you discover a new podcast series you like, and it’s not every day that you start hosting a podcast series either!  To bookend this inaugural season of Absolute Gene-ius, Jordan and Cassie interview each other to provide a retrospective look at the season and to learn more about each other and their respective career paths.

Polymerase chain reaction (PCR) was discovered in 1983 by Kary Mullis and Michael Smith, who were jointly awarded the Nobel Prize in Chemistry in 1993. Since then, PCR has been a cornerstone method that has been a pillar of discovery and applied science. The various types of PCR are sometimes confusing, and the relative pros and cons of each method are not always clear, which is why it’s so great to have this episode's guest explain them all in a simple and clear-cut way. 

Bioinformatics is a relatively new field of science that is very interdisciplinary in nature. Its practitioners use a mixture of biology, chemistry, physics, statistics, and computer science to develop methods and software aimed at helping integrate and understand biological and other data.  

There are very few remaining locations on Earth that are untouched by humans, and those that do remain are in very extreme environments that are difficult to access.  However, accessing and studying life in these extreme environments can provide unique insights to the biology of life. Understanding how simple organisms adapt and survive in seemingly unlivable conditions is a unique field of study with the potential to inform and affect the human condition.  

This mid-season message from Cassie includes the announcement of the arrival of Jordan’s first baby, which will mean a short delay in production of the second half of the season.  We will be back soon though with more great conversations with the Gene-iuses using dPCR to progress their science.  In the meantime, we hope you’ll constructive feedback via absolute.geneius@thermofisher.com or in a review on whatever service you stream us through.  We also hope you’re tell a friend about us so that they can catch up on back episodes during the break. Stay curious!

Microbial consortia are groups of diverse microorganisms that have the ability to act together in a community. Such consortia are common in nature and are known to play important roles in many ecosystems but are not always well understood. Soil management and nutrient mobilization are one area where complex communities of microbes are known to be important, whether it be a naturally occurring consortium, or a man-made consortium.  

The use of model organisms in science dates to ancient Greece and represents an important way humans have progressed our collective understanding of biology and disease. We’ve probably all heard of using mice, rats, or even Drosophila melanogaster (i.e., fruit flies) in the lab, but zebrafish have surged in their use as a model organism. Zebrafish are small, more cost effective to maintain, have a fast generational lifecycle, and have clear embryos that enable direct observation of their development. As is the case with any model system used across the globe, standards matter and help make results transferrable to other studies.  This is where our guests come into the picture.  

Parasites may bet a bad rap overall, but they play a vital role in healthy ecosystems. In this episode, we focus on the role parasites play in freshwater ecosystems. Specifically, we’re talking about the role of avian schistosomes, a very interesting parasite that infects waterfowl, but that also uses snails as a host in its larval stage. Larvae also infect humans to cause what’s know as swimmer’s itch.
