Step by step
Solved in 2 steps
- How efficient the whole process of apoptosis inducing ion channels can be?Which component of cell division machinery is frequently targeted by anti-cancer drugs? Can you explain the common side-effects of chemotherapy (e.g. hair loss, mucositis) based on this information?How is apoptosis involved in cancer? Describe the role of apoptosis in cancer and identify what molecules are involved. Cite your references. asap.
- The frog Xenopus laevis has often served as a model system for the study of apoptosis. Can you think of some reasons that frogs are particularly good models for the study of apoptosis?Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent of human breast cancers, HER2 is permanently activated, resulting in unregulated cell division. Lapatinib, a drug used to treat breast cancer, inhibits HER2 receptor tyrosine kinase autophosphorylation (the process by which the receptor adds phosphates onto itself), thus reducing tumor growth by 50 percent. Besides autophosphorylation, which of the following steps would be inhibited by Lapatinib? Signaling molecule binding, dimerization, and the downstream cellular response. Dimerization, and the downstream cellular response. The downstream cellular response. Phosphatase activity, dimerization, and the downsteam cellular response.A cell begins to undergo apoptosis due to stress. Which of the following are true about this cell? (select all that apply) The cell can exit apoptosis if the stressful factor is removed The cell has high levels of p53. The cell's DNA will inevitably degrade The cell may undergo mitosis before completing apoptosis
- Mention what are the important functions of apoptosis? discuss brieflyArtificially induced apoptosis (controlled cellular death) is found to be an effective treat- ment for some forms of cancer. Which of the following describes the most likely mechanism by which apoptosis might be induced? A B с D by causing ribosomes to increase the rate of protein synthesis by triggering the division of mitochondria in the cell to increase ATP production by increasing the expression of membrane-bound glucose protein channels by causing lysosomes to release digestive enzymes into the cytosolHow interfered regulatory machinery results in production of tumor?
