Why is the tumor microenvironment important to cancer progression?
Step by step
Solved in 3 steps
- The "initiation" stage of cancer refers to: a) The stage where DNA is mutated, and permanent DNA damage occurs b) The stage during which the mutated cells develop into a malignant cell population c) The stage during which "promoters" enhance the further development of the mutated cells d) The stage during which cancer breaks away from the primary origin and metastasizesWhat 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 the difference between benign and malignant tumors? What is the disadvantage of this classification?One of the major characteristics of cancer is uncontrolled proliferation of cells. There are several more characteristics of cancer, name TWO more:How is an inmortal cancer cell line different from a regular cancel cell line ?
- Which of the following is true of tumor suppressor genes? Group of answer choices a) If this gene is overactive, it becomes an oncogene b) If one of the alleles is mutated, there is usually little effect. Two inactivating mutations are usually required for loss of function (recessive mutation). c) If one copy is lost, the gene no longer functions (dominant mutation) d) Tumor suppressors genes usually cause mitosis or cell growth e) Tumor suppressor genes decrease apoptosisWhat does the cancer stage refer to?Although cancer is not a contagious disease in humans or other vertebrates, there have been rare cases in which cancers have spread from one organism to another. Describe three cases of these contagious cancers and what conditions might have led to their appearance.
