In this lesson, we are going to be taking a look at cancer cells and identifying which option is the most plausible way of causing cancer cells to undergo apoptosis.
00:17
There can be multiple correct answers, so let's go through them.
00:22
First, let's start with defining what cancer really is.
00:27
Cancer is categorized by uncontrolled cell division.
00:31
Where the cells bypass the normal regulatory mechanisms of the cell cycle.
00:36
Apoptosis, or programmed cell death, is a critical process that eliminates damaged or unnecessary cells.
00:43
And inducing apoptosis in cancer cells is a key therapeutic strategy.
00:49
So let's examine the options.
01:05
Option 1.
01:07
Targeting the g2 checkpoint by using drug therapy to activate checkpoint proteins.
01:12
This would be plausible.
01:19
The g2 checkpoint verifies that dna replication in s phase has been completed correctly before the cell enters mitosis.
01:28
Activating checkpoint proteins could halt the cell cycle if errors are detected, potentially leading to apoptosis if the damage is irreparable.
01:37
Option 2.
01:46
Targeting the s -checkpoint by using chemotherapy to cause organelle replication to stop.
01:53
This would be less plausible.
01:57
While chemotherapy can target rapidly dividing cells and interfere with dna replication, the s -phase checkpoint primarily monitors dna damage rather than organelles, the organelle replications.
02:11
Chemotherapy that damages dna to activate the checkpoint might be a more accurate description.
02:23
Option 3.
02:25
Targeting the metaphase checkpoint by using drug therapy to activate spindle fiber proteins.
02:32
This would be plausible...
