Cell Cycle Regulation 2
Storyboard Text
- These cancer cells will then spread to the rest of your body.
- What usually causes cancer is control over the cell cycle has broken down.
- Exactly. A mutation in DNA that regulate cell growth and division causes cancer.
- There are several ways that mutations could occur, first when a cell is dividing or when chemicals, smoke and all that is entering your body, or they can also be caused by the cell's own biological activities.
- oh...
- They can also occur from genes that make cancer more likely to appear.
- When a cell grows too quickly, it is more likely to acquire mutations and less likely to repair damaged genes.
- Is there a treatment or cure for all this?!!
- Yes, of course. I will get into that in a bit. We try to limit apoptosis because it allows cancer cells to live longer. Also allows more time for mutations to develop.
- which can accelerate tumour severity, and conflict with division during tumour growth. We don't want that.
- Yes of course, we wouldn't like that.
- Oh, cyclins are what control the cell cycle. Which leads us to internal regulators, which help the cell cycle to make sure no mistakes occur.
- Another thing is external regulators, which make cells either speed or slow down the cell cycle. Sometimes the cell might not respond to these regulators.
- Thats good to hear, that there is a treatment. Let us talk to Isabelle's father and give you a response by tonight. Thanks so much, bye!
- Thank you guys!!
- Or chemotherapy to kill cancer cells or slow their growth. Depending on Isabelle's case, and whichever you prefer.
- So some treatments include, surgery to remove the tumor, or radiation which would destroy cancer cell DNA...
