Absolute Gene-ius

Cancer research is moving fast, and molecular tools are helping scientists see more, measure more, and ask better questions.

In this Science Snapshot episode of Absolute Gene-ius, Jordan Ruggieri and Lisa Crawford revisit memorable oncology-related clips from past conversations. Dr. Raquel Munoz explains how CAR-T cells are engineered to recognize and kill cancer cells, and how PCR-based methods can help confirm successful modification and track CAR-T expansion. Dr. Dustin Rubinstein shares how CRISPR and genome editing are being used to create pig models, including “onco-pig,” that may better reflect aspects of human cancer biology than traditional models. The episode also connects cell-free DNA research from Dr. Lee Ann Baxter-Lowe to oncology applications, before turning to Dr. Kathie Sollweck’s discussion of circulating tumor DNA and the sensitivity needed to detect low mutational burden in liquid biopsy research. Finally, Valeria Rangel offers practical perspective on multiplex PCR assay design.

And because it is Absolute Gene-ius, the science comes with some laughs, a few pig jokes, and a reminder that even complex oncology methods can be surprisingly fun to talk about.

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.

The career corner brings a mix of honesty and humor, from chaotic CRO workdays to broken PCR capillaries and runaway lab mice, paired with thoughtful advice on navigating industry paths, building GMP expertise, and finding the right fit between academia and industry.

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

In this crossover episode, Absolute Gene-ius welcomes Steve Lewis, host of Speaking of Mol Bio and Director of Product Management at Thermo Fisher Scientific. Steve discusses why PCR remains so broadly relevant across research and applied science, from human identification and food testing to gene synthesis and molecular characterization. He also explores emerging trends shaping molecular biology workflows, including multiplexing, assay design, customization, miniaturization, and the ongoing need for high-quality PCR plastics. The conversation also digs into sustainability in the lab, including why single-use plastics remain essential for reducing contamination risk and how more sustainable material sourcing can help reduce carbon impact without compromising performance.

In Career Corner, Steve shares a winding path that started in communications, moved through startups and home brewing, and eventually led to bioprocessing, biosecurity, synthetic biology, and product management. His advice? Cultivate curiosity, surround yourself with good people, and try not to drop your E. coli flask.

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.

From spilled drink mishaps to science fiction inspiration, the career corner brings humor and humanity. Dr. Philibert reflects on mentorship, passion, and the joy of seeing students turn ideas into impactful innovations, proving that science is as much about people as it is about discovery.

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

In this Science Snapshot, we revisit standout moments from past episodes to explore how multiplexing is applied across research areas, from measuring interferon-related genes in lupus to analyzing complex microbial communities and detecting low-level donor-derived DNA. 

Guests highlight both the opportunities and challenges, including assay design, probe optimization, and troubleshooting strategies. The episode also showcases how multiplexing enables entirely new applications, such as comparing chromosome ratios, assessing molecular integrity, and distinguishing functional mRNA from truncated byproducts. Whether using qPCR or digital PCR, multiplexing allows researchers to extract more information per sample, improve precision through multiple data points, and better reflect biological complexity. As platforms and chemistries continue to evolve, multiplexing is becoming more accessible, helping scientists move faster, conserve material, and focus more on interpreting results rather than optimizing reactions.
