| 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) |
| gene expression | <molecular biology> The full use of the information in a gene via transcription and translation leading to production of a protein and hence the appearance of the phenotype determined by that gene. Gene expression is assumed to be controlled at various points in the sequence leading to protein synthesis and this control is thought to be the major determinant of cellular differentiation in eukaryotes. (18 Nov 1997) |
| differential gene expression | Gene expression that responds to signals or triggers; a means of gene regulation; e.g., effects of certain hormones on protein biosynthesis. (05 Mar 2000) |
| expression, gene | A gene speaks. When a gene is expressed, the information encoded in the gene is translated into protein or RNA structures present and operating in the cell. Expressed genes include genes that are transcribed into messenger RNA (mRNA) and then translated into protein as well as those genes that are transcribed into RNA (such transfer and ribosomal RNAs) but not translated into protein.

| appetite regulation | Physiologic mechanisms which regulate or control the appetite and food intake. (12 Dec 1998) |
