The phrase "all classes of expression" is correct and usable in written English.
It can be used when referring to various types or categories of expression, such as artistic, verbal, or written forms.
Example: "The conference will explore all classes of expression, including literature, visual arts, and performance."
Alternatives: "all forms of expression" or "all types of expression".
Interestingly, the association between preferred codons and evolutionarily conserved residues was confirmed for all classes of genes regardless of expression breadth or expression level (table 5).
A set of 616 transcripts showing significant (false discovery rate <0.1) differences between the BMP4-treated Dicer-null and wild-type NS cells was hierarchically clustered to aid visualisation of the different classes of expression differences detected (Fig. 5J, K).
Expression was detected across all four genotypes for 27,355 unigenes, genome-specific expression patterns were observed for 7,851 unigenes and 180 unigenes displayed other classes of expression pattern.
This analysis confirmed the expression profile predicted by AFLP for the ESTs analyzed and identified three classes of expression profiles.
This difference indicates that, in contrast to metazoans, fungal genes might not generally fall into two main classes of expression.
In such cases, all available data are analyzed but with an artefact due to the misalignment of values included in similar classes of expression level, compared to their sample of origin.
We grouped the 349 genes into three classes of expression levels with respect to their intensity values above background levels (i.e, BG-tag) with class 1 as low (not-detected), class 2 as medium (possibly detected) and class 3 as high level of expression (detected), respectively.
For validation qRT-PCR was performed for 20 randomly selected genes from different classes of expression levels and fold changes resulting in a significant correlation of r = 0.98 (Additional files 17 and 18).
Importantly, lower conservation in larger genomes was observed for all classes of operons in terms of gene expression, essentiality, and balanced protein concentration.
Thus, transcripts exhibiting highly significant over expression in all classes of abnormal astrocytes, including trisomic BG01V APCs, CCF-STTG1 astrocytoma cells and glioblastoma patient samples with respect to diploid H9 APCs (Table 1, GND > C) may be diagnostic markers of transformation and/or potential therapeutic targets (i.e. changes in gene expression that are consequences of transformation).
