The phrase "analysing the expression of" is correct and usable in written English.
It can be used in contexts where you are examining or interpreting the way something is expressed, often in academic or analytical writing.
Example: "In this study, we are analysing the expression of gene activity in response to environmental changes."
Alternatives: "examining the manifestation of" or "investigating the representation of".
Gene expression profiling studies involving multiple clinical samples were performed analysing the expression of specific transcripts in different data sets available through Gene Expression Omnibus.
To evaluate the prognostic potential of serum CCL2 (sCCL2) and serum TNF-α (sTNF-α) in nasopharyngeal carcinoma (NPC) before treatment by analysing the expression of these two markers.
The osteoblastic phenotype of the cells was confirmed by analysing the expression of bone-specific genes (Runx2, osteocalcin, osteopontin, and osteonectin) by semiquantitative reverse transcriptase polymerase chain reaction (PCR).
Therefore, we undertook a study to examine miRNA expression and regulation of ATF6 in CF and non-CF airway epithelial cells in vitro and in vivo, and complemented these human studies by analysing the expression of key miRNAs in a mouse model of CF lung disease.
We followed the transcriptional responses downstream Smad2/3 activation in the absence of protein synthesis by analysing the expression of the direct target gene Pitx2, by quantitative PCR (Figure 3B).
The current study aims to rectify this situation by analysing the expression of the neuronal activity marker Fos to investigate the neuroanatomical substrates underlying primed reinstatement of cocaine-induced CPP.
To verify that Dp140 is indeed expressed in the adult cerebral cortex and cerebellum, we analysed the expression of Dp140 as described above for Dp427p.
After treatment with inducers, cells were lysed using RIPA buffer and total protein was used to analyse the expression of AhR, Cyp1A1 and Cldn4 by western blot.
To understand whether GC plants were able to induce a full defence response at the molecular level, we analysed the expression of the SA-dependent defence marker gene PR-1.
To test whether Treg cell population was changed or not in Rag2 KI mice, we analysed the expression of FoxP3 that acts as the transcription factor of regulatory T cell lineage specification on CD4+ T cells.
