Q

Normal vs Cancer Cells

Can easily detach from each other?

A

17
Q

Normal vs Cancer Cells

Stay bound together

A

Normal

18
Q

Normal vs Cancer Cells

Controlled cell division

A

Normal

19
Q

Which of the following is FALSE?

Cancer cells display a loss of contact inhibition

Cancer cells are characterized by controlled cell division

Cancer cells are resistant to apoptosis

Cancer is a group of diseases

A

Cancer cells are characterized by controlled cell division

20
Q

Why is cancer so difficult to treat?

A

Cancer cells continue mutating and become resistant to therapies

Many chemos are cytotoxics and reach dose-limiting toxicities before cancer can be eradicated

Targets for inhibition which have counterparts w/ important functions in normal cells

Cancer trends can change over time

21
Q

In the cell cycle, where is cancer formed?

A

From G0 to G1 transition; cancer cannot enter G0

22
Q

T/F

Cancer is caused by novel genes

A

False; caused by mutations of existing genes

23
Q

What are the main types of protein kinases?

A
  1. Tyrosine
  2. Serine
  3. Threonine
