AP Art History

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Term
Definition
Proteins that regulate cell check points   Retinoblastoma protein (pRb), p53, p21  
🗑
Proteins in BCL-2 Family   Bak, Bax, bcl-2  
🗑
Bak   Encourages apoptosis. Stimulated release of cytochrome c from mitochondria, activating classes, stimulating death  
🗑
Bax   Encourages apoptosis. Stimulated release of cytochrome c from mitochondria, activating classes, stimulating death  
🗑
Bcl-2   Prevents apoptosis  
🗑
Hyperplasia   Increase in number of normal cells  
🗑
Dysplasia   Presence of cells that are abnormal but not cancer  
🗑
Mutation in which gene causes Li-Fraumeni syndrome   p53  
🗑
Sex Hormone-Binding Globulin   Made by liver. Bonds to sex hormones to keep their levels regulated  
🗑
Insulin-like growth factor 1   Stimulates tumor growth, angiogenesis, and metastasis  
🗑
mSEPT9   Involved in cell division. Form of this protein tested for in colon cancer blood tests. Found in colorectal cancer cells.  
🗑
CA-125   Cancer Antigen 125. Protein found in blood. Cancer cells secrete more of it  
🗑
Carcinoma   In epithelial cells (skin, hollow organ lining, various tissues)  
🗑
Basal cell and squamous cell carcinomas   Carcinomas in skin cells  
🗑
Adenocarcinomas   Form in glandular cells in epithelial tissues that secrete fluids. (Some breast cancers, prostate cancer, lung sometimes, and pancreatic sometimes)  
🗑
Melanoma   Melanocytes are cells that secrete melanin. Located in stratum basale (chemo resistant)  
🗑
Sarcoma   Mesoderm turns into mesenchyme. Mesenchyme develops into connective tissue (bone, fat, cartilage, blood). Sarcomas=cancer from mesenchyme tissues. Rare but return and spread  
🗑
Osteosarcoma   Bone sarcoma. High grade (usually in kids) divide a lot and don’t resemble bone  
🗑
Soft tissue sarcoma   Develop in muscle, fat, nervous tissue, and blood vessels  
🗑
Lymphoma   Originate in white blood cells (lymphocytes). Hodgkins and non-hodgkins  
🗑
Leukemia   Start in bone marrow or blood. Lymphoblastic come from immature white blood cells. Myeloid come from immature blood cells. White blood cell count increased  
🗑
Blastoma   Come from immature cells in fetus. Genetically formed  
🗑
Alkylating agents   Chemo type. Create bulk adduct. Create DNA damage cancer cell can’t repair. P53 will then stimulate cell death.  
🗑
Alkylating agents drawbacks   Doesn’t work for p53 mutated cells. Bone marrow suppression  
🗑
Antimetabolties   Chemo type. Look like components used in copying DNA during S phase. Interfere with DNA copying (block folic acid, insert themselves into dna (intercalation), block transcription, cause breaks in DNA)  
🗑
Topoismerase inhibitors   Chemo type. Topoismerase enzymes prevent dna from supercooling. These stall replication machinery  
🗑
Mitotic inhibitors   Chemo type. Block cells from doing mitosis. Bind to spindle apparatus, microtubules, and actin components  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
