Incoming air flow is regulated solely by varying the opening of the intake valves.
Rejecting the industry's view that it should be regulated solely by antitrust principles, the court said the F.C.C. rules were a justified deterrent to "monopolistic domination in the broadcasting field".
Since we possess little information on the regulation of ERK5 activity, in particular to its specific-phosphatase and the regulation of this phosphatase, we have hypothetically defined an ERK5-specific phosphatase (BMKSP), which is regulated solely by pERK5, and feeds back to negatively regulate pERK5.
To ensure identifiability, we included three genes that are regulated solely by hsf1 (HSPA80, HSPandand COL4A1), and two genes that are regulated solely by ppara (ACSL1 and HMGCS1).
Using this system, we describe novel LTβR-responsive genes that were regulated solely by RelA or RelB or by both RelA and RelB.
NO differs from other neurotransmitters in that its levels are regulated solely by synthesis, rather than by storage, release or targeted degradation.
Additional predicted alternative promoter regions must be studied to verify whether SEPT9 isoforms are regulated solely by DNA methylation or by alternative mechanisms as suggested previously [ 48].
These findings suggest that Enh and PrL candidates coordinately regulate transcription of a subset of target genes in mouse ES cells, while other genes are regulated solely by PrL signatures.
If the activity of a transcription factor is regulated solely by phosphorylation, for example, this approach will not be able to identify it as a regulatory influence on its target genes.
Interestingly, EFNA3 appeared to be regulated solely by HIF-1 (78% reduction in EFNA3 expression by siHIF-1α relative to siLuc), where HIF-2α knockdown was without effect on the hypoxia-induced transcript level.
