Episode Summary:  Millions of people die every year from chronic diseases. Traditional drug discovery has failed in identifying solutions to many of these persistent health challenges. Functional genomics is offering a way forward by identifying gene networks and enabling the development of drugs with very specific targets. But, rather than just relying on gene targets within humans, Linda and her company, Fauna Bio, are casting a wider net across the animal kingdom. Extreme adaptation is common across many mammals, giving us an incredible pool of potential targets to go after. Whereas a ..read more

Episode Summary The expression of genes in our genome to produce proteins and non-coding RNAs, the building blocks of life, is critical to enable life and human biology. So, the ability to predict how much of a gene is expressed based on that gene’s regulatory DNA, or promoter sequence, would help us both understand gene expression, regulation, and evolution, and would also help us design new, synthetic genes for better cell therapies, gene therapies, and other genomic medicines in bioengineering. However, the process by which gene transcription is regulated is incredibly complex; thus, predic ..read more

Episode Summary:   In this very special episode of Translation, Seth is joined by Ash Trotman-Grant to demystify spinning out from academia. Much of this knowledge has so far only been available to select groups of academics and PhD founders are at a disadvantage – some potentially breakthrough technologies  never saw the light of day and didn’t get a chance to have a real impact. We want to bring the power of the tech transfer process back to entrepreneurial scientists. Enter the Spinout Playbook – your complete guide to spinning out of academia. In this episode, we chat about the P ..read more

Episode Summary Chimeric antigen receptors, or CARs, repurpose the build-in targeting and homing signals of our immune system to direct T cells to find and eliminate cancers. Although CAR-T cells have transformed the care of liquid tumors in the circulating blood, like B cell leukemia and lymphoma, CAR-T therapy has shown limited efficacy against solid tumors. To unlock the full potential of CAR-T therapies, better receptor designs are needed. Unfortunately, the space of potential designs is too large to check one by one. To design better CARs, Dan and his co-author Camillia Azimi developed CA ..read more

Episode Summary:  DNA is an ideal molecule for storing information in our genomes because it’s stable, programmable, and well understood. The same qualities make DNA a great building block or construction material for nanoscale biomolecular structures that have nothing to do with our genome, like molecular scaffolds created by folding DNA into 2D and 3D shapes. This technology is known as DNA origami. However, the practical applications of DNA origami are limited by spontaneous growth and poor reaction yields. Anastasia developed a method that uses crisscross DNA polymerization of single ..read more

Episode Summary:  Evolution is happening even at the cellular scale. Whether it's a virus, a bacterial pathogen, or a cancer cell, disease-causing agents are responding to the therapies we throw at them, updating their genes and molecular pathways to resist death. As a trained microbiologist, Nick Goldner and his co-founder Chris Bulow spent their years in grad school using -omics data to overcome antibiotic resistance in bacteria which led to their first company Viosera. As they struggled with the harsh realities of the antibiotics market, they stumbled upon the connection between bacter ..read more

Episode Summary:  When COVID-19 hit and society decided to use mRNA vaccines for the first time, many questions remained about whether RNA itself was ready for the challenge. But three scientists at Stanford University who had barely worked with each other before the pandemic realized that RNA’s limitations were merely a design challenge and not an issue with the substrate itself. Through emails and zooms, Kathrin, Gun, and Hannah built a tool to massively test RNA designs. With it, they screened for RNA with better functionality, increasing the stability and expression of the protein the ..read more

Episode Summary: COVID-19 tests have become synonymous with jamming a swab up our nose to find out whether we have an active infection. But as we progress through this pandemic, a test that tells us whether people have antibodies against the virus will be massively important to creating public health initiatives and deciding who to vaccinate next. Unfortunately, these serology tests are exceedingly tedious to perform, inhibiting their widespread use. Realizing this problem, Susanna talks us through how she utilized protein engineering to create a novel serology test that is massively easier an ..read more

Episode Summary: Brain machine interfaces untangle the complex web of neurons firing in our brains and relay the underlying meaning to a computer. These devices are being adapted to help patients regain motor control, monitor our mental well being, and may one day even make us more empathetic. State of the art methods to do this have massive trade-offs, either being high resolution yet requiring devices to be embedded in our heads or low resolution but non-invasive. Finding a key middle ground, Sumner uses advances in ultrasound to monitor the brain activity of monkeys performing specific tas ..read more

Episode Summary: Enzymes that break down other proteins, or proteases, could be used as a powerful therapeutic if they could specifically chew-up disease causing entities. However many proteases are non-specific, breaking any protein in their path, while the specific ones target proteins that would provide no therapeutic benefit. Travis and his colleagues developed a riff on the method known as PANCE that utilizes bacteria and bacterial viruses known as phages to evolve proteins toward a specific goal. With it, he retrains the sequence-specific protease, botulinum neurotoxin, toward new target ..read more
