Cancer cells typically lose cell cycle entry control. Explain how the following mutations, which are found in some cancer cells, lead to a bypass of these controls: (a) overexpression of cyclin D, (b) loss of Rb function, (c) loss of p16 function, (d) hyperactive E2F.
nges to this answer. Question 36 Which of the following is not a common characteristic of cancer cells? O loss of control of the cell cycle O presence of chromosomal rearrangements (translocations, inversion, deletions) O loss of contact inhibition O ability to initiate apoptosis (cell death) appropriately
Briefly Explain why cell injury due to genetic causes are alarmingly increasing each year
My question is two fold. What are some diseases that cause and/or are caused by apoptosis? Also if apoptosis is the most common form of programmed cell death in animals, what other forms of programmed cell death are there? Thank you.
(b) What is the role of microtubules in mitosis? How does vincristine contribute to the cell cycle arrest of cancer cells? Explain. Microtubules
Briefly describe the cell cycle, its checkpoints, and the general proteins required to move past each checkpoint. For each cell cycle checkpoint, be sure to describe what the cell is "checking for" and how this "check" occurs, along with the result if the checkpoint cannot be passed. Your answer should also include a description of the structure of MPF, its regulation, and its general targets or functions. Be sure to include any accessory molecules or proteins involved in regulation of MPF, while also describing the process by which MPF is formed and activated. In this answer, you should also choose two proteins involved in the cell cycle, which, if mutated, will cause cancer. Describe these proteins and their normal functions, and then show how a mutation in these proteins will result in cancer.

Artificially induced apoptosis (controlled cellular death) is found to be an effective treat- ment for some forms of cancer. Which of the following describes the most likely mechanism by which apoptosis might be induced? A B с D by causing ribosomes to increase the rate of protein synthesis by triggering the division of mitochondria in the cell to increase ATP production by increasing the expression of membrane-bound glucose protein channels by causing lysosomes to release digestive enzymes into the cytosol
Which statements are true? Explain why or why not.1 Since there are about 1013 cells in an adult human,and about 1010 cells die and are replaced each day, webecome new people every three years.2 In order for proliferating cells to maintain a rela-tively constant size, the length of the cell cycle must matchthe time it takes for the cell to double in size.3 While other proteins come and go during thecell cycle, the proteins of the origin recognition complexremain bound to the DNA throughout.4 Chromosomes are positioned on the metaphaseplate by equal and opposite forces that pull them towardthe two poles of the spindle.5 Meiosis segregates the paternal homologs intosperm and the maternal homologs into eggs.6 If we could turn on telomerase activity in all ourcells, we could prevent aging.
The expression patterns as well as activation of different types of CDKs happen at different stages of the cell cycle. Explain why.
Changes in the activity of a variety of Cdks are essential for accurate progression through the cell cycle, and yet the levels of Cdk expression are fairly constant during the cell cycle. Briefly describe three mechanisms by which the activity of Cdks is regulated.
