Cancer cells do not respond to the body's normal stop and go signals for growth and differentiation, becoming "deaf" to the community of cells that make up the human body. In this sense, which of the following are ways that a cancer cell becomes "deaf"? Cancer cells may make their own growth factor to stimulate their own growth Cancer cells may activate a receptor that signals growth in the absence of a growth factor Cancer cells may produce pro-apoptotic proteins to signal their own death Cancers cells may express cyclins that override cell cycle arrest controls Cancer cells can transmit vascular endothelial growth signals to recruit their own network of blood vessels Cancer cells up-regulate surface proteins that enable the immune system to detect them

Step 1
Cancer cells may make their own growth factor to stimulate their own growth: This statement is true, as cancer cells can produce growth factors that stimulate their own growth, making them "deaf" to the normal stop signals. Show more…

Cancer cells have a number of key features in common, which were described in class as a list and have also been put forth in a model of the Hallmarks of Cancer. For Question 4 (parts 1-4), match each description with the cancer hallmark to which it most applies. There is only one answer for each description, so pick the best option from the hallmarks listed. Not all the hallmarks will be used. In cell culture, cells are no longer subject to contact inhibition and growth in a monolayer, and will grow above the monolayer in clusters. [ Choose ] Cells divide in the absence of mitogen signalling and grow in the absence of growth factor stimulation. [ Choose ] Loss of functional p53 leads to loss of response to cellular stress and DNA damage signals. Evading apoptosis Cells maintain telomere length by expressing

A cancer cell undergoes cell division in an unregulated manner (for example, when no growth factors are present). Alterations of the following factors could cause cells to exhibit such 'uncontrolled growth' characteristics. Determine whether the gene encoding the specified factor behaves like an oncogene/proto-oncogene or a tumor suppressor gene. Briefly explain your reasoning. A kinase that functions in a growth factor signal transduction pathway. A CDK that functions in cell cycle regulation. A kinase that functions to turn off the CDK described in part b. A cyclin that functions with the CDK described in part b. A growth factor receptor.
