Step by step
Solved in 2 steps
- In order for certain cancers to propagate, they require a growth factor known as Vascular Endothelial Growth Factor (VEGF). What does VEGF signal the cell to do and how does this promote the propagation of cancer cells?What properties are gained during tumor progression that contribute to malignant behavior and metastasis?What are the heritable changes in cells that contribute to cancer development?
- What is the role of the microenvironment in cancer development and progression?What are the underlying biological mechanisms that differentiate the various types of cancer, and how can a better understanding of these mechanisms lead to more targeted and effective treatments for each specific type of cancer?What is Cancer Epigenetics ?
- What is required to enable a cancercell to metastasize?Explain what is fundamental aberrations in all cancer cells ?#1) Hyperplastic growth are not cancerous yet but show a higher than normal proliferation rate. True False #2) When cancer cells have not spread beyond its original site, the term used to describe it is benign growth intraepithelial neoplasia carcinoma stage 3 carcinoma in situ #9) Cancer cells generally have missense mutations in p53 gene, resulting in truncated p53 normally active p53 dominant negative p53 inactive p53 #10) Single or double stranded breaks in DNA activate Chk 1 and 2 kinases, which phosphorylates p53. This results in --- in the level of p53 in the cell. increase decrease
