Chapter 21, Problem 3NST

Because of its accessibility and biological significance, the proteome of human plasma has been intensively studied and used co provide biomarkers for such conditions as myocardial infarction (troponin) and congestive heart failure (B-type natriuretic peptide). Polanski and Anderson compiled a lise of 1261 proteins, some occurring in plasma, that appear to be differentially expressed in human cancers [Polanski, M., and Anderson, N. L. (2006) Biomarker Insights 2:1–48]. Of these 1261 proteins, only 9 have been recognized by the FDA as tumor-associated proteins. First, what advantage should there be in using plasma as a diagnostic screen for cancer? Second, what criteria should be used to validate that a cancerous state can be assessed through the plasma proteome?

A particular type of anemia in humans, called b-thalassemia,results from a severe reduction or absence of the normal b-globinchain of hemoglobin. However, the g@globin chain, normally onlyexpressed during fetal development, can functionally substitutefor b-globin. A variety of studies have explored the use of thenucleoside 5-azacytidine for the expression of g-globin in adultpatients with b-thalassemia.(a) How might 5-azacytidine lead to expression of g-globin inadult patients?(b) Explain why this drug may also have some adverse side effects.
Briefly describe the following properties of the Ras GTPases: a) Size, structure and cellular localization (for structure I want to know if they are lipidated and any other unique features) , b) How are they activated and inactivated (i.e. include the GEFs and GAPs), c). Give an example of downstream effector proteins, d). Are they or could they be involved in human cancer.
Cancer can be defined as an abnormal proliferation of cells that defy the normal regulatory controls observed by normal cells. Recently, histone deacetylation therapies have been attempted in the treatment of certain cancers [reviewed by Delcuve et al. (2009)]. Specifically, the FDA has approved histone deacetylation (HDAC) inhibitors for the treatment of cutaneous T-cell lymphoma. Explain why histone acetylation might be associated with cancer and what the rationale is for the use of HDAC inhibitors in the treatment of certain forms of cancer.
