Related to gene expression: Regulation of gene expression

expression

 [eks-presh´un]
1. the aspect or appearance of the face as determined by the physical or emotional state.
2. the act of squeezing out or evacuating by pressure.
gene expression
1. the flow of genetic information from gene to protein.
2. the process, or the regulation of the process, by which the effects of a gene are manifested.
3. the manifestation of a heritable trait in an individual carrying the gene or genes that determine it.

gene ex·pres·sion

1. the detectable effect of a gene.
2. appearance of an inherited trait; for many genetic (for example, recessiveness, hypostasis, parastasis) and environmental (the absence of pertinent challenges) reasons, a gene may not be expressed at all. In those circumstances, it will have no impact on Darwinian evolution.

gene expression

Genetics The process by which a gene's coded information is translated into the structures present and operating in the cell. See Gene, mRNA, Protein, RNA, Transcription, Translation, tRNA.

gene ex·pres·sion

(jēn eks-presh'ŭn)
1. The detectable effect of a gene.
2. Appearance of an inherited trait; for many reasons, a gene may not be expressed at all.

gene expression

the processes effecting the transfer of information encoded in the GENE to the functional gene product (PROTEIN or RNA). Generally, gene expression is equated with the processes of TRANSCRIPTION and TRANSLATION. However, where the gene product is RNA only transcription is involved. A gene that is expressed is an active gene.

"As these processes require a lot of skilled labour and time, there is an indirect impact on the pricing of the entire gene expression products," elaborates Dr.
Expression profiling could also become a powerful diagnostic tool, with each disease state being characterized by a typical gene expression pattern, or "signature" (van Ommen et al.
The data demonstrated an agreement of 69% between gene expression in blood and brain amyloid using PET imaging as the reference.
The contribution of mining biological association between genes using improved Pearson's correlation proximity-based hierarchical clustering (PCPHC) for gene expression data analysis includes the following:
The RNA polymerase cannot bind to DNA and gene expression will be inhibited or silenced (Sirtuins are human enzymes analog to the Silent Information Regulation 2 -SIR 2 - proteins of yeast).

Results: BMAL1, CLOCK, PER2 and CRY2 gene expression levels were markedly suppressed after day-time anaesthesia in the both brain and liver, but night-time administration caused only temporary suppression of gene expression.
To assess whether the CsEXP 10 gene genetically regulated fruit set and early fruit development in cucumbers, the relative CsEXP 10 gene expression was studied in pollinated fruit and unpollinated ovaries at -2, 0, 1, 2, 3, 4, 5 and 6 DPA.
The new software was designed to be part of a comprehensive solution to make scalable single-cell gene expression analysis possible for every lab, from sample to discovery.
In the present study, we hypothesized that co-culture of preadipocytes with myoblasts would modify the effects of saturated and unsaturated fatty acids on adipogenic and lipogenic gene expression.
[USPRwire, Fri Jan 23 2015] Gene expression is the biological process where genetic information is used for the synthesis of a functional gene product, either RNA or protein.
Gene expression profiling can bring significant improvements to disease profiling and diagnoses based on genetic disposition.
