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.

RNA sequencing and identification of differentially expressed genes
Based on the above mentioned 908 differential factors (including differentially expressed genes, miRNA and lncRNA), co-expression networks were constructed by using WGCNA package in R language.
With the aforementioned list of top 66 genes that were taken from the differentially expressed genes cutoff at adjusted p value < 0.01, we performed the analysis with the gene function classification tool from NIH DAVID [17], which has the capability of addressing the enriched and redundant relationships among many-genes-to-many-terms and can reduce the complexity of gene list.
Differentially expressed genes with FDR [less than or equal to] 0.05 were considered statistically significant.
Using TRED (Transcriptional Regulatory Element Database) database (http://rulai.cshl.edu/TRED), transcription factors interacting among the 1075 expressed genes were predicted and analyzed, and 887 genes were found to correspond to 18 transcription factors (Table 2).
The differentially expressed genes among treatment groups were analyzed using R package DESeq2 by the Laboratory for Statistical Genomics and Systems Biology at the University of Cincinnati with a [absolute value of log2 fold change] > 1.5 and [P.sub.adj] < 0.01 considered to be statistically significant.

In Siberian wild rye grass (Elymus sibiricus L.), this technique has been very useful for detection of heat stress-induced differentially expressed genes for first time (Lee et al., 2015).
The differentially expressed genes (24 h compared with 0 h, 48 h compared with 0 h and 96 h compared with 0 h) were selected using a threshold of absolute value of log2 (fold change) >1 and FDR 99%) were used for further analysis.
At the genetic level, the presence of abnormally expressed genes further confirmed the hypothesis that the ONH is closely related to the occurrence of POAG.
