| genes, suppressor | Genes that inhibit expression of a previous mutation. They allow the wild-type phenotype to be wholly or partially restored. (12 Dec 1998) |
|---|---|
| genes, suppressor, tumour | Genes that inhibit expression of the tumourigenic phenotype. They are normally involved in holding cellular growth in check. When tumour suppressor genes are inactivated or lost, a barrier to normal proliferation is removed and deregulated growth is possible. (12 Dec 1998) |
| breast cancer susceptibility genes | Inherited factors that predispose to breast cancer. Put otherwise, these genes make one more susceptible to the disease and so increase the risk of developing breast cancer. Two of these genes, BRCA1 and BRCA2, have been identified (and prominently publicised). Several other genes (those for the Li-Fraumeni syndrome, Cowden disease, Muir-Torre syndrome, and ataxia-telangiectasia) are also known to predispose to breast cancer. However, since all of these known breast cancer susceptibility genes together do not account for more than a minor fraction (1/5th at most) of breast cancer that clusters in families, it is clear that more breast cancer genes remain to be discovered. (12 Dec 1998) |

See related entries to: BRCA1; BRCA2; Breast cancer, familial. (12 Dec 1998) |
| amber suppressor | <molecular biology> A tRNA molecule which suppresses amber mutations because it has mutated to recognise the amber codon UAG (which normally signals that the translation of mRNA into an amino acid chain should stop) as a signal for inserting whatever amino acid it carries into the chain. As a result, it can prevent the amino acid chain from ending before it is completed. (09 Oct 1997) |
| suppressor | A compound that suppresses the effects of mutation or suppresses what would be a normal course of events. (05 Mar 2000) |
| suppressor cell | <immunology> Lymphocyte class of cells suppressing T or B antigen dependent responses. (18 Nov 1997) |
| suppressor cells | Cells of the immune system that inhibit or help to terminate an immune response, e.g., suppressor macrophages and suppressor T-cells. Synonym: cytotoxic cell. (05 Mar 2000) |
| suppressor factor | <immunology> Factors released by T suppressor cells. See: suppressor mutation, ochre suppressor, opal suppressor. (19 Jan 1998) |
| suppressor factors, immunologic | Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-j) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory. (12 Dec 1998) |
| suppressor mutation | <molecular biology> Mutation that alleviates the effect of a primary mutation at a different locus. May be through almost any mechanism that can give a primary mutation, but perhaps the most interesting class are the amber and ochre supressors, where the anticodon of the tRNA is altered so that it mis reads the termination codon and inserts an amino acid, preventing premature termination of the peptide chain. (18 Nov 1997) |
| suppressor-sensitive mutant | A conditionally lethal, host range, bacteriophage mutant that produces nonsense codons and can replicate only in a host bacterium able to translate the nonsense codon; the mutation's effects are lethal (i.e., prevent replication of the virus) in a bacterium without such a suppressor mechanism. (05 Mar 2000) |
| suppressor T-cell | <immunology> See T-cells. (18 Nov 1997) |
| suppressor tRNA | The tRNA associated with a suppressor mutation. (05 Mar 2000) |
