For Whom the Cell Tolls: Cancer Biology

This episode covers the basics of how a cancer begins. Genetic mutations can often knock out genes responsible for keeping an eye on how many cell divisions are allowed. Once these are out of the way, aggressive growth genes can overcome them and cause initial tumor populations to form. After further successive survival advantages are gained, tumors eventually break free from their original organ/tissue and wreak havoc. Learning how to address the initial and final stages of cancer are key towards better clinical outcomes for all patients.

Chimeric Antigen Receptor T-cells (CAR-T) represent one of the most profound and exciting advances in modern medicine and science. Many lymphoma patients fail therapy after therapy with little recourse. CAR-T aimed to stop that. Taking immune T-cells from the patient, engineering them to target cancer cells, and re-releasing them into the patient would’ve sounded crazy 20 years ago. Thanks to modern technology, science, and clinical practice we’ve created something powerful. The CAR-T enter patients and attack the tumor, but a massive immune reaction can induce massive side effects. This episode explores some of the exciting news, future possibilities, and ethical challenges of CAR-T use for lymphoma treatments. I hope you enjoy!

We live in an age where social media provides a platform for everything - good and bad. I wanted to summarize how ideas can be spread, weaponized, and distorted, much like a disease. We also briefly go over the differences between ideas and beliefs. The episode takes a look at how stem cell clinics offer hope through social media without a solid foundation of biology with which to apply their therapies (that nobody knows how to control or stop from hurting people). Cancer can be an unfortunate consequence of visiting one of these clinics. We can reflect on how easy it would be for trusted health professionals to turn to social media to market "Miracle Cancer Cures", taking advantage of anyone looking for hope. The same hope that cancer patients need to fight their disease is poisoned by willfully ignorant endeavors like these. Learning how to harness science, logic, ideas, and human emotion is a key to overcoming the aggressive advance of non-well-meaning products. Emotion trumps logic in the courts of social media, and health professionals need to be ready to confront these challenges from the same perspective (or a dual one) instead of relying on scientific findings alone. Facts can convince you, but emotion can make you believe.

This is an exciting and quick episode that mainly covers the findings of a recent Daniel D. Carvalho paper in Nature Reviews called “Epigenetic therapy in immune oncology” where the authors elaborate on new mechanisms of cancer treatments. Essentially, the epigenetic Cancer therapies that cause genes to reprogram the “on/off” state also awaken ancient relic viruses that lie dormant in our DNA, which subsequently leads to a massive immune response against the tumor. These mechanisms may play a role in treating aggressive forms of the disease that usually evade the immune system. Enjoy!

Domestication is a very interesting process and was first performed millions of years ago. The relationships between humans and dogs is of particular interest, as are the genetic and developmental changes that make them possible. We also delve into controversy and how the process of tameness selection brings along more than what’s expected. Enjoy, and go hug your dog or cat!

Today’s episode is the first one that is primarily driven by literature and philosophy, namely borrowing themes explored in Frankenstein and Paradise Lost. Victor Frankenstein’s fraught relationship with his creature is a devastatingly emotional purview into what life is. The influence from Paradise Lost and our subsequent relationship with a creator initiates a powerful dialogue worth exploring. General aspects of being creative are also introduced, and human control of life and healthcare conclude the episode. Either way you look at it, advances are mounting without as much central appreciation or critique. It’s a discussion I’d encourage you examine. Enjoy!
