The phrase "a markedly reduced level" is correct and usable in written English.
It can be used to describe a significant decrease in quantity, intensity, or quality of something.
Example: "The study found that there was a markedly reduced level of pollutants in the water after the new regulations were implemented."
Alternatives: "a significantly lower level" or "a considerably diminished level".
Our data demonstrated the correlation between the level of RR and the increased levels of dNTPs in the group of 0.5 μM treatment for 24-h with a markedly reduced level of dFdCTP.
Human DCs are comparable to murine DCs in exhibiting a markedly reduced level of lysosomal proteolysis.
Depletion of either PC4 or CK2 resulted in a markedly reduced level of in vitro transcription (Supplemental Figure S1B).
Mutants of D. melanogaster that express a markedly reduced level of eIF4E-2 show defects in anterior-posterior axis formation during early embryogenesis [ 48].
Men with coronary artery disease (CAD) confirmed by angiography have a markedly reduced level of circulating T as compared to those with normal coronary arteries [ 13- 18].
Electrophysiological recordings taken from DVMN neurons in acute brainstem slices showed a markedly reduced level of DVMN activity (~60%) in older αβγ−/− mice (1.2 ± 0.1 vs 2.3 ± 0.2 Hz in WT mice; P =.04, Wilcoxon rank sum test) Figure 6D and Figure 6E.
The markedly reduced level of maternal care shown by that strain, however, might mask potential effects of the GR mutation taking the form of a further decrease of maternal care, which might be at odds with the minimum requirement to ensure pups' survival.
In these epithelia, individual calyceal units were observed either to display a control-like pattern, with colocalization of CASPR1, tenascin-C and KCNQ4 in the junction area, or to display an abnormal pattern, with markedly reduced levels of CASPR1 and tenascin-C and dispersed KCNQ4 labeling (Fig. 6A).
Each of the infected mice developed markedly reduced levels of an OVA-specific IgG antibody compared to the controls (Fig. 6A).
These cells also expressed some surface CD74, an observation that explained their responsiveness, but contained markedly reduced levels of total cellular CD74.
Using the same polysomal profiling technique described above, we found that compared to wild type larvae, tor null larvae had markedly reduced levels of polysomes and an increase in subpolysomal fractions (Fig. 8A).
