| paracrine | <endocrinology> Form of signalling in which the target cell is close to the signal releasing cell. Neurotransmitters and neurohormones are usually considered to fall into this category. (18 Nov 1997) |
|---|---|
| paracrine communication | Cellular signaling in which a factor secreted by a cell affects other cells in the local environment. This term is often used to denote the action of hormones on surrounding cells. (12 Dec 1998) |
| appetite regulation | Physiologic mechanisms which regulate or control the appetite and food intake. (12 Dec 1998) |
| gene expression regulation | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action at the level of transcription or translation. These processes include gene activation and genetic induction. (12 Dec 1998) |
| gene expression regulation, archaeal | Any of the processes by which cytoplasmic or intercellular factors influence the differential control of gene action in archaea. (12 Dec 1998) |
| gene expression regulation, bacterial | Any of the processes by which cytoplasmic or intercellular factors influence the differential control of gene action in bacteria. (12 Dec 1998) |
| gene expression regulation, developmental | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action during the developmental stages of an organism. (12 Dec 1998) |
| gene expression regulation, enzymologic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in enzyme synthesis. (12 Dec 1998) |
| gene expression regulation, fungal | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in fungi. (12 Dec 1998) |
| gene expression regulation, leukaemic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in leukaemia. (12 Dec 1998) |
| gene expression regulation, neoplastic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in neoplastic tissue. (12 Dec 1998) |
| gene expression regulation, plant | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in plants. (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) |
| gene regulation | The DNA and protein interactions in a gene that determine the temporal and spatial modes of expression as well as the amplitude of expression. (14 Nov 1997) |
| regulation | 1. <biology> The adaption of form or behaviour of an organism to changed conditions. 2. <embryology> The power of a pregastrula stage to form a whole embryo from a part. Origin: L. Regula = rule (18 Nov 1997) |
