The phrase "a marginal expression" is correct and usable in written English.
It can be used to describe an expression or phrase that is not widely accepted or is used infrequently in a particular context.
Example: "In academic writing, using a marginal expression can sometimes confuse readers who are unfamiliar with the terminology."
Alternatives: "a peripheral expression" or "a minor expression".
For these pixadores, ensuring that pixação remains a marginal expression of the urban periphery – as opposed to a marketable commodity – is essential to its very survival.
Immunocytochemical staining of these cells revealed the expression of alpha smooth muscle actin (α-SMA, Fig. 3L, M), whereas the formed bodies showed only a marginal expression of the α-SMA (Fig. 3G).
When expressed in E. coli, full-length caspase-3 (procaspase-3) undergoes presumable autoprocessing to yield the appropriate subunits characteristic of the active enzyme with only a marginal expression level, probably due to its cytotoxicity [ 19].
By identifying genes with the highest expression in a population of canine osteosarcoma and marginal expression in a population of human osteosarcoma patients, two of four "dog-like" genes, IL8 and SLC1A3 (IL-8, p = 0.0201; SLC1A3, p = 0.0264), were defined that were negatively associated with survival in a distinct human osteosarcoma data set.
Interestingly, we observed that the inhibition of Nodal signaling with increasing doses of Lefty leads to a progressive reduction of rasl11b marginal expression (Figs. 3J M, here only four representative doses are displayed).
For this reason, it is important to determine whether a marginal level expression can improve life quality and prolong lifespan.
With the exception of a marginal elevated expression of HLA-DR in the presence of HBV, which may lead to enhanced DC-T cell interactions and viral immunity, the overall inability of HBV to activate pDC may underlie this defective innate immune response.
It is currently unclear whether such marginal expression can improve the clinical outcome in a severe DMD model.
The 180 genes that had been 'gained' at S/N = 6 were ubiquitously expressed within all CNS samples and in addition showed marginal expression outside the CNS.
In this analysis, probesets associated with no or marginal expression across all 45 samples were discarded resulting in 5,865 differentially expressed genes.
For the ligand-receptor compatibility analysis, probesets associated with no or marginal expression across all 45 samples were discarded resulting in 5,865 differentially expressed genes.
