Cancer Cells Gone Wild!
Cancer Cell Surrounded by T-cells and dead
How are cancer cells different from most cells? Do not have a normally functioning cell cycle Divide excessively and can invade other tissue
Tumor Abnormal mass of cells Skin Lung
Normal vs. Tumor Growth
Benign Vs. Malignant Benign-mass of normal cells at original site Malignant- cancerous and can spread to other cells
Tumor Abnormal mass of cells
Metastasis Spread of cancer cells beyond their original site
Metastasis of prostate tumor cells Into bone cells
Carcinogens Any substance involved in the promotion of cancer: gamma rays, X-rays, UV rays Dioxin (pesticide) Tobacco smoke Asbestos HPV virus
Cancers are named According to the tissue or organ in which they originate
4 types of Cancers Carcinomas Sarcomas Lymphomas Leukemias
Carcinomas Cancers that originate on external or internal coverings (skin, lining of intestine)
Sarcomas Arise in tissue that support the body (bone and muscle)
leukemia cancer in leukocytes (white blood cells) in bone marrow (too many white blood cells and not enough red blood cells)
lymphomas malignant cells in the lymph system
Lymphatic System Works with circulatory system to filter clear fluid (transports white blood cells) Lymphatic System You TubeLymphatic System You Tube
Cancer Gene Checker The p53 Tumor Suppressor Gene Triggers Cell Suicide
FYI p27 on chromosome 12 Inhibitor of cdk regulator of cell cycle High levels of p27 shown in breast cancers
Normal Cell Divisions Mammalian Cells will divide about 50 times in a culture
3 ways to treat cancer 1. Surgically remove 2. Radiation 3. Chemotherapy
Radiation Treatment To kill cancer cells Usually X-rays and gamma rays to target the cancer cells
Cancer Fighting Drugs: work on mitotic spindles TAXOL Paclitaxol Freezes the mitotic spindles after it forms From Yew plant VINBLASTIN Prevents mitotic spindles from forming From periwinkle
Cancer. Cancer is one of the most common diseases in the developed world: 1 in 4 deaths are due to cancer 1 in 17 deaths are due to lung cancer Lung cancer.
CELL DIVISION AND CANCER Unit 7 - Mitosis. Mitosis All cells in your body divide In children and teens, cells divide to assist in growth In adults,
Cancer “Mitosis Gone Wild”.
CANCER By: Amanda Herrod.
Cancer What is cancer? How does it form? How can it be treated?
Another way to think of cancer is “Mitosis Run Amok.”
Understanding Cancer and Related Topics
+ How is the cell cycle regulated? Sections 8.8 and 8.9.
What do you know about cancer?
A cancerous cell is caused by a faulty reproduction system. The cell continues to reproduce at a very fast rate When cells reproduce at an abnormally.
Cell Cycle Regulation & Cancer
Your “Do Now” 3/19 Take a paper from up front
Sexual v. Asexual Reproduction. Binary Fission Chromosome Structure Eukaryotic chromosomes contain DNA and protein tightly packed together to from chromatin.
10.3 Regulating the Cell Cycle
SC430 Molecular Cell Biology
1. Cancer and the cell cycle
8.7 Mutations KEY CONCEPT Mutations are changes in DNA that may or may not affect phenotype.
Non-infectious Disease. What is it? Disease that does not spread from person to person Usually chronic Examples: –Cancer –Allergies –Diabetes –Autoimmune.
