Welcome to a special episode where I'm joined by 11 of my Minnesota State students as we close out our Cancer Biology lecture! We weave through discussions surrounding generational causes of cancer, potential next-generation hallmarks, treatment & financial ethics, and what the future hold for this disease as a whole.

All said, this one is super fun because there are contributions from pre-med, pre-dental, and pre-STEM students in the room. These 11 wanted to be here, and their enthusiasm shows. I'm grateful for this group and the opportunity to teach.

The basic answer is no. When faced with R-CHOP resistance, DLBCL patients now have the option to utilize genetically modified Chimeric Antigen Receptor T-cells (CAR-T) designed to hunt tumors. This episode investigates the recent controversy into if these super-cells can transition into a villainous tumor themselves. We cover a paper by Garcia et. al. that showcases how much power we are adding to CAR-T, even activating oncogenes to do it. Next, we transition to a large analysis from Stanford where 724 patients are examined, with 1 developing a T-cell tumor. Sequencing this case reveals that no synthetic vector DNA integrations or activity is within the tumor. It ends up revealing a great surprise about shared evolutionary pathways between B & T-cell progenitor stem cells. Enjoy the episode!

Welcome back! It's been a while. I'm excited to get going again with an episode on the emerging science of "ecotyping" the cells around tumors - the microenvironment. Ecology and Evolution of lymphoma tumors is only half the story. We needed to know more about the state of cells around the tumor. How do they affect the surrounding immune cells? Do they support the tumor? We examine the worst possible scenario: when very little remains except for tumor and support cells. What are the consequences for immune-specific therapies like CAR-T cells? Hopefully this episode provides a good intro to our new tools to measure the TME and how it can further advance precision cancer medicine. I hope that you enjoy!

What do you think? Would the immensely powerful amount of data be a game-changer for medicine? Or does DNA sequencing miss too much of the picture to be worth the cost? This question is an example why we need leaders that understand Biology as genomics becomes hyper-accessible. I do my best to discuss the primary Pros and Cons of each side, along with possible modifications to the proposal. Enjoy!

This episode covers how gene therapy may emerge as a critical tool for medicine as we seek to treat the previously untreatable. Can we ADD genes to specific cells to help humans overcome fated genetic ailments? Why has this process challenged us in the past? And lastly, who is going to pay for all these expensive viral delivery systems? Join to take a first look at how medicine and genetics can change the future.
