The phrase "action of the expression" is not commonly used in written English and may be unclear in meaning.
It could be used in contexts discussing the effects or implications of a particular expression or statement, but it may require additional clarification.
Example: "The action of the expression in this poem evokes a strong emotional response from the reader."
Alternatives: "effect of the expression" or "impact of the expression".
In order to explore whether VPA has potential as a treatment for pancreatic cancer, we examined the effects and mechanism of VPA action on the expression of MICA and MICB in human pancreatic cancer cells.
Taken together, all these results demonstrate that one of the mechanisms through which melatonin can modulate aromatase enzyme in breast tumour cells is through its downregulatory action on the expression of COX enzymes, which decrease the levels of PGE2.
Moreover, leptin upregulated its own receptor, Ob-R, that could reinforce leptin actions on the expression of IL-1 system.
To determine the mechanism of action of the DualU6GFP expression system, we examined transfected cells for dEGFP protein levels, dEGFP mRNA levels and the presence or absence of small RNAs encoded by the U6 convergent expression vector containing an EGFP-specific insert.
Amongst the specific molecular targets mediating the actions of neurosteroids, the expression of α2-GABAAR in the PVN (see Section 3.1 and Fig. 1) may be of particular significance for their anxiolytic and stress-protective actions (Fig. 1).
To investigate whether biochar has a similar mode of action, the expression of this callose synthase-encoding gene, OsGSL1, was investigated by quantitative reverse transcriptase PCR (qRT-PCR) in biochar-amended and non-amended plants.
We sought to examine how a combination of EMT inducers (EGF, ST), which each have different cellular effects and speed of action, influence the expression of the E-cadherin repressor gene set and downstream EMT effectors in this breast carcinoma cell line.
To examine their potential sites of action, the expression profiles of xSCT, xSCTR and lfSCTR transcripts were studied by the quantitative PCR technique (Fig. 4).
To determine the mode of gene action affecting the expression of phenotypic variation in fitness-related traits, we used line cross analyses, specifically joint scaling tests, as described in Chapter 9 of Lynch and Walsh [ 71].
In a second paper [ 14], Young and colleagues address the other side of metalloproteinase action, the expression of the inhibitor TIMP (tissue inhibitor of metalloproteinases).
