| regulatory region | <molecular biology> A DNA base sequence that controls gene expression. (14 Oct 1997) |
|---|---|
| regulatory regions or sequences | A DNA base sequence that controls gene expression. (05 Mar 2000) |
| regulatory sequence | <molecular biology> DNA sequence to which regulatory molecules such as promotors or enhancers bind, thereby altering the expression of the adjacent gene. (18 Nov 1997) |
| regulatory sequences, nucleic acid | DNA sequences involved in regulating the expression of other genes. (12 Dec 1998) |
| regulatory T-cell | <immunology> Vague term for any class of T lymphocyte not directly involved in the effector side of immunity, but involved in controlling responses and actions of other cells, especially T helper and T suppressor cells. (18 Nov 1997) |
| myogenic regulatory factors | A family of muscle-specific transcription factors which bind to DNA in control regions and thus regulate myogenesis. All members of this family contain a conserved helix-loop-helix motif which is homologous to the myc family proteins. These factors are only found in skeletal muscle. Members include the myod protein (myod protein), myogenin, myf-5, and myf-6 (also called mrf4 or herculin). (12 Dec 1998) |
| public utility regulatory policies act | (PURPA) A federal law requiring a utility to buy the power produced by a qualifying facility at a price equal to that which the utility would otherwise pay if it were to build its own power plant or buy power from another source. (05 Dec 1998) |
| sequence, regulatory | A sequence of bases in DNA that controls the expression of a gene. (12 Dec 1998) |
| acute viral conjunctivitis | An epidemic inflammation of the conjunctiva marked by follicles, especially in the lower fornix; may be caused by adenoviruses, herpesvirus, and Newcastle disease virus. (05 Mar 2000) |
| antibodies, viral | Immunoglobulins produced as a response to viral antigens; includes all classes of immunoglobulins elicited by all viral components. (12 Dec 1998) |
| antigens, viral | Substances elaborated by viruses that have antigenic activity. (12 Dec 1998) |
| antigens, viral, tumour | Those proteins recognised by antibodies from serum of animals bearing tumours induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation. (12 Dec 1998) |
| avian viral arthritis virus | A virus of the genus Reovirus, family Reoviridae, causing tenosynovitis and arthritis in chickens. (05 Mar 2000) |
| bronchiolitis, viral | An acute inflammatory disease of the upper respiratory tract, caused by paramyxoviruses, occurring primarily in infants and young children; the viruses most commonly implicated are parainfluenza type 3 and respiratory syncytial virus. (12 Dec 1998) |
| gene expression regulation, viral | Any of the processes by which cytoplasmic factors influence the differential control of gene action in viruses. (12 Dec 1998) |
