The mean expression rate was <γ> = 7.3±0.3, with moderate cell-to-cell dispersion (COV = 0.25).

Plosone

The rate and radicality in paralogs displays a weaker relation with mean expression rate and variance of expression rates across tissues than in single copy genes.

BMC Genomics

Logarithm of mean expression rate across 26 tissues [ 39] was used as a measure of expression rate in each paralog; coefficient of variation across tissues was used as a measure of non-uniformity of gene expression.

Biology Direct

As expected, substitution rates and radicalilty decreased with mean expression rate in the whole fly and increased with the coefficient of variance of expression rate across larval and adult tissues [ 22] (Fig. 5), corroborating previously observed patterns of stronger selective constraints in highly expressed genes and in household genes [ 23- 25].

BMC Genomics

As predicted, there was a strong positive correlation between asymmetry of paralogs' evolution and their mean expression rate and a negative correlation (with a statistically intangible hint of a maximum) with the CV of expression across 26 tissues sampled by FlyAtlas [ 39].

BMC Medical Genomics

Signed difference between log-transformed mean expression rates (faster paralogs – slower paralogs) was significantly less than 0 (Two-tailed t-test: df = 275, t = 6.53, P < 2E-10 for all pairs; df = 162, t = 7.39, P < 4E-12 for pairs with Z > 1 and df = 49, t = 6.60, P < 2E-8 for pairs with asymmetry surviving χ2 test with false discovery rate adjustment [ 39] at q < 0.1).

Each overexpressed gene in the list can then be assessed by the Student t test to calculate the P or Q values (false discovery rate) [21] [23], mean expression values (mean 1, mean 2), and the normalized Student t value.

Plosone

We compared the expression noise of genes with the same effective transcription and translation initiation rates resulting from the action of different repressors, whereas previous studies compared the noise of genes with the same mean expression level but different initiation rates.

Biophysical Journal

The stochastic variation in all simulations in this study is determined by adding a zero-mean Gaussian value to the basal expression rate.

Expert writing Tips

Best practice

When reporting the "mean expression rate", always specify the units of measurement (e.g., transcripts per cell per hour) and the statistical measure of dispersion (e.g., standard deviation or standard error of the mean).

Common error

Avoid using the term "mean expression rate" without specifying the gene or protein being analyzed. Provide sufficient context to ensure clarity and avoid ambiguity.

Linguistic Context

The phrase "mean expression rate" functions as a noun phrase that typically serves as the subject or object of a sentence. It refers to the average speed or frequency at which a gene is transcribed and translated into a protein. As Ludwig AI suggests, it is a correct and usable phrase.

FAQs

How is "mean expression rate" typically measured?

The "mean expression rate" is commonly measured using techniques like qRT-PCR, RNA sequencing, or flow cytometry, followed by statistical analysis to determine the average expression level across a population of cells or samples.

What does a high "mean expression rate" indicate?

A high "mean expression rate" generally indicates that a gene is highly active or expressed in a particular cell or tissue, leading to increased production of its corresponding protein. But remember that depending on the protein's normal function, it can have different consequences in the context of biological experiments.

What factors can affect the "mean expression rate" of a gene?

Various factors can influence the "mean expression rate" of a gene, including transcription factors, epigenetic modifications, environmental stimuli, and cellular signaling pathways.

What is the difference between "mean expression rate" and "gene expression level"?

While related, "mean expression rate" refers to the speed at which a gene is expressed, while "gene expression level" refers to the amount of gene product present at a given time. The rate influences the level, but other factors like degradation rates also play a role.
