The phrase "average expression at" is correct and usable in written English.
It can be used in contexts where you are discussing the mean or typical value of a certain expression or measurement at a specific point or condition.
Example: "The average expression at this time point indicates a significant increase in gene activity."
Alternatives: "mean expression at" or "typical expression at".
A total of 293 genes with an average expression at least 3-fold or higher in adenocarcinomas compared to non-adenocarcinoma samples were identified, with a false discovery rate of<.00001%.
Based on a re-sampling analysis, each of these 51 peaks and 49 troughs was significantly different than the average expression at all time points in the cluster from which they were identified (P < 0.01; see Methods).
The average expression at baseline was 2.3 fold lower in T2DM compared to controls (p = 0.003) and MetS subjects showed a 1.5 fold lower expression compared to controls (p = 0.03).
They show, on average, expression at 2 logarithmic lower levels than protein-coding genes and it has been suggested that they can be expressed in a more cell type-specific manner than protein-coding genes [ 11, 13, 14].
Probe sets whose average expression differed at least 1.5- or 2-fold at p<0.05 between cells maintained in the presence or absence of tetracycline were considered as differentially expressed.
Subsequently, we compared all possible combinations of average expression value at each time point, and selected expressed targets with more than two-fold differences in at least one pairwise comparison from cycling genes.
Initially we selected for tags with an average expression of at least 3 per 100,000 tags.
In our method, one cycle with average expression value at every time point of three successive cycles is used to reduce the noise and error.
For PrImR, average expression patterns at 48 hpf were obtained after image registration of in situ confocal scans on a common reference axonal scaffold, as described in [ 47].
We extracted the data for these 16 genes, as well as all of the genes in each of the GO or KEGG categories identified by the GeneTrail analyses, and calculated an average expression value at each time point.
Next we applied a filter that would include only those tags with an average expression of at least 5 or 10 counts per 100,000 tags in 30% or more of the tumors, respectively for anaplastic astrocytomas and glioblastomas.
