Why are cyclin-dependent kinases such hot targets for cancer therapy?

Why are cyclin-dependent kinases such hot targets for cancer therapy?

Expert Solution

Cell cycle checkpoints are the regulatory points where the events occurring in cell cycle are checked and the transition to next stage of the cell cycle is controlled. This is done with the help of special proteins called cyclins. The amount of these proteins increase and decrease in every stage. These proteins are responsible for activating enzymes called as cyclin-dependent kinase. These enzymes are responsible for phosphorylation of cell cycle control proteins and therefore control the transition to next stages of cell cycle.

Cancer cells are the cells which have the ability to divide uncontrollably. They keep on replicating even if there is any damage in the cell. This damage occurs because these cells do not respond to cyclins and cyclin dependent kinases. If there is a mutation in gene encoding for cycling and cyclin dependent kinases, then the control over cell cycle is lost and this results in the formation of cancerous cells.

Please rate high.

Suppose that a mammalian cell line is heterozygous at the sole locus encoding the cyclin dependent kinase of MPF. One allele encodes Active CdK, the other allele harbors a nonsense codon. Now, in one cell, a mutation occurs that introduces a frame shift into the active copy of this Cdk? What happens with this mutated cell? It divides on It gets stuck in G2 It gets stuck in G1 It gets stuck in S phase

You are working in the cancer therapy division of a hospital. This hospital treats cancer by hitting a tumor with high energy protons from a cyclotron. When the protons leave the cyclotron they are going at half the speed of light. You are in charge of deflecting the protons so they hit the patent's tumor. This deflection is accomplished by passing the proton beam between two flat, parallel electrodes that have a length of 10.0 feet in the entering beam...

Which of the following is not true about cyclin-dependent kinase (CDK): a. It’s present only during the M phase of the cell cycle b. When CDK is combined with cyclin, the MPF (Mitosis Promoting Factor) formed initiates mitosis c. It’s a protein that controls other proteins using phosphate groups d. It’s present at all times during the cell cycle
