The phrase "a direct functional" is not correct in standard written English.
It seems to be an incomplete expression and lacks clarity without additional context.
Example: "The system requires a direct functional approach to solve the problem effectively."
Alternatives: "a direct function" or "a straightforward function".
These observations, however, are correlative rather than proof of a direct functional role for CD38 in this cellular function.
Experimental studies have demonstrated a direct functional role of serotonin in bone metabolism, independently of hyperprolactinemia or growth hormone levels.
To further examine whether PLD1 is a direct functional target of miR-638 in GC cells, we performed a series of functional restoration assays.
As to the high salt derived particles, it appears that they might not have a direct functional relevance to RbfA and RsgA, due to the high salt treatment.
This method, which has a direct functional analysis approach, does not approximate the eigenvalues of the Laplacian as those of a finite linear operator.
Combinatorial stimulation-inhibition analysis using a direct functional reengineering approach can aid in rapidly unravelling stable information about the coarse-grained structure of large-scale drug action from high throughput screening experiments.
Thus, we conclude PKIα is a direct functional target of miR-155.
Therefore, this will be the first time a direct functional link between Akt and Bmi-1 is made.
For example, the positive or negative genetic interaction between two genes does not specify a direct functional relationship without additional information [18].
To overcome these difficulties we combined a direct functional assay based on electrophysiology with a direct binding assay based on label-free tryptophan fluorescence.
This is in agreement with a recently described transcriptional independent role of STAT3 in mediating MTs dynamics and cell migration through a direct functional interaction with stathmin [27].
