The phrase "a single pathway in" is correct and usable in written English.
It can be used when describing a specific route or method of entry into a system, process, or location.
Example: "The research indicates that there is a single pathway in the brain that regulates emotional responses."
Alternatives: "one route into" or "a sole entry point to".
Accordingly, our gene profiling in early Fe deficiency strongly suggests that the induction of genes by Fe deficiency is not begun by a single pathway in the regulation network, but involves multiple pathways and multiple components of activators even in early Fe deficiency.
Involvement of a single pathway in the control of mutually exclusive processes may have relevant implication in the evolution of multicellularity.
Breast cancer treatment would be simpler if a single protein regulated a single pathway in all cancer cells.
Therefore "IL6 pathway" cannot be labelled as a subset of a single pathway, in this case only as a subset of two pathways.
These data suggest that targeting a single pathway in SCLC may not be efficient enough for successful treatment of this deadly disease.
Of these, 34 are assigned a single enzymatic activity rather than a panel of alternate substrates, with the reaction belonging to a single pathway in human as documented by KEGG.
However, the distribution is patchy, that is, NISE are scattered among different metabolic pathways, with not a single pathway identified in which all reactions would be catalyzed by multiple non-homologous isoforms.
The expansion of the PDCD4 gene family may have provided specificity of function if different PDCD4 isoforms are involved in different pathways or interact with different receptors within a single pathway such as in ethylene signaling.
Thus, a requirement of a maximum information rate of proteins at the NM implies that proteins from a single pathway travel together in a pulsed cloud, causing the largest number of proteins per unit area to reach the NM in the minimum amount of time.
Tel1 and the Mre11 complex seem to act in a single pathway for telomere length maintenance in budding yeast because single and double mutants have similarly short telomere lengths (Ritchie and Petes, 2000).
Not a single pathway consistently stratified prognosis in all five iterations in the five datasets.
