Lesson on the Wnt/β-Catenin signaling pathway (also known as simply the Wnt signaling pathway), including an introduction to the pathway, Wnt growth stimulatory factors, β-Catenin regulation and role of the pathway in growth, proliferation and development. Wnt proteins act as The Wnt signaling pathway is critically important in embryonic development, particularly in the development of the heart. As such the Wnt/β-Catenin signaling pathway is highly conserved. However, if mutations occur in proteins in the pathway, such as mutations in the adenomatous polyposis coli (APC) gene, this can lead to inappropriate activation of the Wnt/β-Catenin signaling pathway.
NOTE: In the video, I misspoke and said that Beta catenin enters the "mitochondria" - I meant to say it enters the nucleus. Sorry about the confusion everyone. Hope you find the video helpful :)
Hey everyone, here is another biomedical lesson, and this one is on the canonical Wnt signaling pathway. In this lesson, you will be introduced to the Wnt signaling pathway, and the purpose of the Wnt pathway. You will also learn the signaling pathway in a step-by-step fashion, starting with how the Wnt/β-Catenin signaling pathway is regulated during inactivation, how cellular beta catenin levels are regulated by the destruction complex, and how the pathway can become activated by the extracellular signaling Wnt proteins, which are growth stimulatory factors. Finally, you will learn what happens when the APC protein in the destruction complex is mutated, leading to inappropriate activation of the Wnt signaling pathway.

Hey everyone! At 4:12 in the video, I misspoke and said that beta catenin "translocates into the mitochondria". I'm not sure why I said that, but I meant to say "translocates into the NUCLEUS". Sorry for the confusion. I hope you all found this video helpful though! :)

Great video, May I ask this Q: in invasive lobular carcinoma we lack E-cadherin and as Beta-catenin binds to E-cadherin is pathogenesis has to do smt with WNT pathway or just cell-cell adhesion?

This video is very good as a description of the canonical Wnt pathway and how Wnt binding at Fz leads to increased transcription of certain genes. However, there are some issues with the description of Wnt family and the depiction of the destruction complex disassembly is shown incorrectly.

HEY! THANKS A LOT. I'm an electrical engineering student in a struggle to undestand this pathway, and your video was awesome. Because, it was SHORT, and COMPLETE. Thanks really. Some advice tho, please share your references and books for further reading. And please keep doing this kind of videos, specially for people who are not studying health related majors :3
