Absolute Gene-ius – Détails, épisodes et analyse

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. 

Meet Parker Wilson, MD, PhD. Parker is a faculty member Perelman School of Medicine at the University of Pennsylvania, focused on using modern molecular tools to investigate chronic kidney disease. He explains his work phenomenally, both from the general aspects, all the way down to the molecular methods, which include digital PCR. We learn about chronic kidney disease and the interesting genetic mutations associated with it, which Parker and his team are finding, include chromosomal loss. For this application, we hear how dPCR is adept at quantifying chromosome ratios within tissues, and is able to help them spot variations of only a single percent or two. 

Our career corner portion uncovers an academic and career path with uncertainty and challenges one might not expect. Parker helps normalize these challenges and underscores the value of mentors in helping navigate them successfully. In the end, you have a phenomenally intelligent physician scientists sharing his exciting work and his insightful career development advice.

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.

Dr. Clarence Lee, Senior Product Manger at Thermo Fisher Scientific, tells how the QuantStudio™ Absolute Q™ AutoRun dPCR suite helps make the benefits of digital PCR available in an easy-to-use high-throughput system. The conversation covers how automation benefits are provided by MAP16 plates, system software, and the AutoRun plate hotel and loading robot. Clarence also talks about customer applications where he sees automation like this being applied to innovate and drive science forward. 

In the career corner portion, we learn about Clarence’s journey from chemist and biophysicist, to roles in industry and his current role as a product manager. He shares what he loves most about his job and what he’s most proud of over his career that has spanned several diverse roles.

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. 

Our guests for this episode are a couple, and we mean a literal married couple, of reproductive biology experts. Dr. Pavla Brachova and Dr. Nehemiah Alvarez, both working in the Eastern Virginia Medical School’s Department of Physiological Sciences. In their collaborative work they aim to better understand and characterize the role of RNA and cellular events that impact ovarian function in women. We learn about their work with oocytes, which are single cells that grow and mature within the ovary and once fertilized provide the foundations of an embryo capable of maturing to a new individual. They outline how they use digital PCR (dPCR) and other methods to monitor RNA regulation in single cells and how progressing this work and lead to potential RNA-based therapies. 

In Cassie’s career corner we hear childhood stories from each guest and learn about their respective career paths, which eventually collided and merged. They share insights on the importance of having mentors experienced in your field, the challenges of shared job searching, and the joys of collaborating as a couple with shared scientific interests.

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. 

Dave Bauer, PhD, is an Application Scientist at Thermo Fisher Scientific that specializes in real time PCR (qPCR) and digital PCR (dPCR).  He has an educational background in physics, mathematics, and biology, but what’s more important is that Dave loves to help others learn and to break down a topic’s complexities to make it more understandable and approachable.  In this episode we hear Dave explain the difference between qPCR and dPCR, the importance of Poisson statistics to dPCR, dead volume, reaction chamber volume consistency, and more.  We learn how qPCR and dPCR complement each other and how they relate to sequencing methods for applications like single nucleotide polymorphism (SNP) detection.  

As you’ve come to expect from Absolute Gene-ius, you also get a good sense of who Dave is and how he got to his current role. We learn about how he knew right away that academia wasn’t for him, how he ended up unexpectedly working in forensics after his PhD, and how he eventually landed in his current Application Scientist role. Dave shares some great insights and advice, including how students should care less about their degree’s name and more about what techniques they’re learning and using in their studies.

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.  

Our guest for this episode is Nikhil Ram Mohan, Staff Scientist at the Stanford University School of Medicine. He describes bioinformatics as the bridge to understanding biology. We learn about his international studies and path that brought him to this current role and field of study, and then dive into some of his recent work. Here he and his team analyze biobank samples using digital PCR (dPCR) and quantitative PCR (qPCR) and compare results from the two while correlating results with additional data available for each sample to determine if SARS-CoV-2 RNA detection and quantification in blood can serve to help predict potential for patient coinfection. Their work found that dPCR was able to detect SARS-CoV-2 in samples that were negative when evaluated by qPCR and that a series of biomarkers can help predict coinfection.   

We also get to hear a bit of Nikhil’s interesting personal story, which includes his undergraduate engineering studies in India and leaving his native country for the first time when he moved to the U.S. for graduate school.  We learn how he managed changes in culture, what he loves about teaching, and about him being a new father.

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.  

We’re joined in this episode by Dr. Brandi Kiel Reese and Lydia Hayes-Guastella from the Dauphin Island Sea Lab at the University of South Alabama. They are both geomicrobiologists that study microbial life in extreme environments like the Mariana Trench and Antarctica.  They do an excellent job of painting a picture of how extreme conditions are in these environments and how they manage to collect and preserve samples from such harsh conditions. We learn about the various methods they use to analyze the microbial samples they collect, including the use of digital PCR (dPCR) to detect and quantify transcripts that would otherwise not be detectable given how few cells they’re able to collect.   

Brandi and Lydia also share their unpredictable career path journeys, while sharing some insights and learnings from their respective experiences. We learn what they each love about their work and what qualities is takes to be successful at what they do. Once again, we’re reminded of what a small world it is, especially when you’re in a specialty field such as geomicrobiology of extreme environments.

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.  

In this episode of Absolute Gene-ius Jordan and Cassie talk with Dr. Ray Ketchum form Agrinos about the microbial consortia he and his team cultivate and produce to improve plan health and increase crop yields. We learn about the challenges of fermenting mixtures of more than 20 diverse microorganisms to reproducibly make products that improve plant health and mobilize nutrients in a completely organic way. As you might expect, digital PCR plays in important role in Ray’s R&D and quality control process.  Here, they use dPCR to titer each of the species within their consortia for quality and regulatory purposes, a task that cannot be done by cell culture methods given the range of bacteria involved. 

Cassie’s career corner gets Ray sharing his full career development story from undergraduate, through grad school and postdoc positions, and into his professional career. Ray is generous in sharing his early misconceptions about miscalculations while providing advice to help other avoid similar missteps.
