The phrase "a much larger expression" is correct and usable in written English.
It can be used when discussing mathematical expressions, linguistic phrases, or any context where size or complexity is being compared.
Example: "In this equation, we will simplify the smaller terms before addressing a much larger expression that dominates the calculation."
Alternatives: "a significantly larger expression" or "a considerably larger expression".
QPCR is able to measure much larger expression changes than microarray because of the larger dynamic range of QPCR experiments [ 32].
Such a group-wise approach of GSA covers a much larger spectrum of expression patterns and hence exhibits higher statistical power than an individual-gene analysis: many genes with relatively weak signals as well as small number of genes with strong signals in a gene set could be significant.
Expression of a phosphorylation-resistant GRASP65 mutant T220A/T224A inhibited mitotic Golgi fragmentation to a much larger extent than the expression of the S277A and S376A mutants.
Since the women first burst onto the international spotlight after their 2012 "punk prayer" in Moscow's Christ the Savior Cathedral, the story of Pussy Riot has been emblematic of a much larger crackdown on free expression in Russia.
By contrast, the rpoS mutation had a much larger impact on gene expression in stationary phase.
The high dose exposure caused a much larger effect on mRNA expression, with over 100 transcripts disregulated.
5-aza-dC had a much larger effect on gene expression in HepG2 cells than did TSA, as measured using Affymetrix® HG-U133 Plus 2.0 microarrays.
Essentially, it is easy to imagine that a gene that is strongly differentially expressed in one organ may be determined to be non-differentially expressed in a much larger composite structure due to expression of the gene elsewhere washing out the signal from the small structure.
These results are not surprising since we have previously shown that environmental effects together with adaptation to life in captivity have a much larger influence on brain gene expression in foxes, than selection for tameness [ 11].
While further studies are necessary to explore these possibilities, ISRIB alone modulated the expression of 29 genes (P<0.001), but when combined with Gem, ISRIB altered expression of a much larger set of genes, including genes not previously reported to be associated with ISR pathways.
