  1. When Good Cells Go Bad!! Regulators of Cell Growth and Cancer

  2. Standard(s): • BI5. a. Students know the general structures and functions of DNA, RNA, and protein. • Explanation-5.a.-DNA-double helix-contain genetic info, RNA-single-stranded, copy of a section of DNA, protein-make up many parts of the body

  3. Objectives: SWBAT… • Explain the origin of new cells. • Describe the structure and function of DNA. • Understand that cancer is caused by a malfunction of the cell cycle.

  4. Cell Cycle Regulation • Injuries (broken bones and cuts), need new cells • Cells at edge of injury will rapidly divide producing new cells • When the injury heals cell division slows down

  5. Cell Cycle Regulation • What tells cells to divide, make copies of their chromosomes, or enter another phase of the cell cycle? • Many proteins regulate the cell cycle. • Cyclin – causes a mitotic spindle to form in a non-dividing cell. • Internal and External Regulators (proteins)

  6. What is Cancer? • Body’s cells lose the ability to control growth. • Cancer cells do not respond to signals that control cell growth. • Disease of cell cycle. • Tumors (masses of cells)

  7. Causes of Cancer • Causes – smoking tobacco, radiation exposure, and viral infections • Science can lead us to the cure for cancer • Cancer affects all of us

  8. Cancer Factshttp://www.cancer.org/acs/groups/content/@epidemiologysurveilance/documents/document/acspc-029771.pdf • 2011-571,950 expected cancer deaths • Women-over 240,000 women expected to be diagnosed with breast cancer this year • Men-over 240,000 men expected to be diagnosed with prostate cancer this year • Cancers common in teenagers: Ewing’s sarcoma, leukemia, lymphoma, astrocytoma

  9. Lung Cancer Cells

  10. SkinCancer

  11. Breast Cancer Cells

  12. Summary Questions • How does your body replace a cell after an injury? • Which type of molecules tell the cells to divide and grow? • What is cancer? • How can cancer be caused? • Which types of cancer are commonly found in teenagers?
