Answer #1

Cancer cells divide progressively from one tissue to the another tissue, this is nown as metastasis. Apoptosis is a process which causes programmed cell death with the help of protease enzyme called caspase.The cancer cell mutate the tumour suppresive genes and overexpressed the antiapoptopic genes which prevent tumour formation.

Cancer cell activates the enzyme telomerase which increase the cells life spam. That's why cancer cells are immortal. Cancer cells also have ability of angiogenesis.

Cardamine is a drug that prevents the corpus luteum from forming; follicular cells undergo apoptosis immediately following ovulation. How, if at all, would the hormonal profiles differ between those women taking cardamine and those that were not taking the drug (think about all the hormones levels that may be different)? Why do you expect that?

Which of the following statements about apoptosis is true? Group of answer choices Cells undergoing apoptosis trigger inflammation. Apoptosis does not require an expenditure of cellular energy. Gain of function mutations in apoptosis inhibitors, or loss of function mutations in apoptosis promoters can contribute to development of hematological cancers. Cells undergoing apoptosis swell and then burst open.

How have our perceptions of cancer development changed? Should we be targeting the “Hallmarks of Cancer” by Hanahan and Weinberg that define cancer (sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis), or should the focus be on targeting enabling characteristics that may set the stage for tumor development? Please explain all details, thank you
