A nice start or refresher, although not the deepest as other courses on this platform.

 
Receptor Tyrosine Kinase Pathways are hard to explain
von Diana M. am 27. März 2025 für Receptor Tyrosine Kinase Pathways – Second Messenger Systems

Hi, good day to everyone. I really wanted to make a review for this lecture, because for me it was a great brief and concise explanation. Thank you very much for the easygoing explanation Dr. Cornwall. I have a bachelor in cellular and molecular biochemistry from a US college and never seen anybody explain and organize all this material in a best possible simple way. English is my second language, and I had to study this topic both in English and in my original language, in collage, so I could be able to fully understand how they worked. This type of receptors and cascades involved, are a challenge to explain how they work in a very simple way; while you either try to understand by readding it on a textbook or see it on a picture, Dr. Cornwall does a really good job on how overall it works. To all my fellows studying this lecture, I just wanted to encorage you to remember that she is mainly explaining the overall function of the receptors, the enzymes and proteins involved, don't jump just yet to understanding all the types of pathways that go through the cascade. A quick tip for everyone to understand better this topic with this video: you could try to use both video and script at the same time, pause or rewind if you didn't capture what Dr Cornwall said, and re-read the script, review the slides with the images and write as you understand, that will make engage your brain and fully understand the topic as you go. Thank you again for your explanation Dr. Cornwall; thank you very much everyone for reading me and have a good study session. You all got this!

 
Not a good lecture.
von Larissa K. am 21. Januar 2025 für Cell Cycle Controls

The lecturer doesn't look confident about the subject. The class seems like is incomplete because the lecturer is unable to explain the content.
