The phrase "a mean expression level" is correct and usable in written English.
It can be used in contexts related to statistics, biology, or data analysis when discussing the average or typical level of expression of a variable or measurement.
Example: "The study found that a mean expression level of the gene was significantly higher in the experimental group compared to the control group."
Alternatives: "average expression level" or "typical expression level".
In addition, a mean expression level lower than the maximum expression level subtracted with 2 standard deviation (SD) was a prerequisite for a candidate housekeeping gene.
Other examples include miR-9 with a mean expression level of 15.7, miR-146a with 9.62, miR-134 with 9.81, and miR-195 with 13.2.
We observed increased mRNA expression levels of DNMT3b in the high β group of breast tumors (P = 0.034), with a mean expression level of 5.76 in the low β tumor group and 6.52 in the high β tumor group.
The advanced search option was used to detect probe sets with at least an LRS of 8 (LOD>1.73; p<0.02) and a mean expression level of 8 and 11 in the M430 and exon databases, respectively.
For example, miR-124a had a mean expression level
As a result, a list of 15 genes was suggested with the most constant expression level, based on a coefficient of variation smaller than 4%, a maximum fold change smaller than 2 and a mean expression level lower than the maximum expression level minus 2 times the standard deviation.
(A ) Mean expression levels of genes in both groups.
In previous works, we proposed a gene synthetic circuit to reduce gene expression noise while achieving a desired mean expression level.
Full results of the analysis are shown in Additional file 2. Figure 2 shows the relationship between log2 fold change in expression between Ribo-Zero and poly(A) and mean expression level across all samples.
We found no clear evidence for a correlation between mean methylation level of a CGI and mean expression level of the corresponding genes, but this may be due to the fact that many other factors impact the expression level of a gene, including biological and technical ones.
For the scg-sample MAS5 however provides a considerably larger mean expression level.
