Displaying results 1 to 10.

1. -oma
A suffix meaning a tumor or inflammation, as in granuloma.

2. 12-O-tetradecanoylphorbol-13-acetate (TPA)
A plant phorbol ester which promotes tumor formation by activating membrane protein kinase C.

3. 5-fluorouracil (5-FU)
An anti- cancer agent similar in structure to the nitrogenous base thymine , which inhibits the enzyme dihydrofolate reductase (DHFR) and thus nucleotide synthesis, so that it is particularly harmful to rapidly growing cells such as in tumors .

4. Acoustic neuroma
This is a tumor of Schwann cells in the cerebellopontine angle.

5. Acridine orange
3,6-bis(dimethylamino)acridinium chloride. A toxic, fluorescing dye that stains DNA and RNA and is typically used to identify cancerous tumor cells. When it binds to double-stranded DNA , it fluoresces green; when it binds with the phosphate groups of single-stranded DNA or RNA , it fluoresces orange. The chemical also causes frameshift mutations.

6. Actinomycin D
A relatively toxic antibiotic produced by the fungus like bacterium Streptomyces parvallum. It inhibits RNA transcription in eukaryotes and has antitumor properties, so it is often used in conjunction with other drugs in chemotherapy .

7. Adenocarcinoma
A cancerous tumor originating in glandular tissue.

8. Adenoma
A benign tumor that develops from glandular tissue.

9. Adenomatosis
Abnormal formation of glandular tumors, usually in more than one gland.

10. Agrobacterium tumefaciens
Agrobacterium tumefaciens is a Gram-negative bacterium found in soil which causes crown gall disease in plants (which causes tumor s to form at the crown and at the junction of the root and stem). The tumors are caused by the Ti plasmid in the bacterium; this plasmid is being heavily researched by plant genetic engineers because it is a useful way to introduce new genes into a plant cell.
