The phrase "are regulated at a" is correct and usable in written English.
It can be used in contexts discussing rules, laws, or standards that apply to a specific area or subject.
Example: "The emissions from factories are regulated at a national level to ensure compliance with environmental standards."
Alternatives: "are governed at a" or "are controlled at a".
This can be partially explained by observations that the autophagosome marker ATG8 is rapidly up regulated under starvation conditions in yeast, and that most of the autophagy genes are regulated at a transcriptional level [ 62].
An integrated cellular transcriptomic analysis of small intestinal neuroendocrine tumors identified that they are regulated at a developmental level, have key activation of hypoxic pathways (a known regulator of malignant stem cell phenotypes) as well as activation of genes involved in apoptosis and proliferation.
This manuscript provides an integrated transcriptomic view of small intestinal neuroendocrine tumors and identifies that these lesions are regulated at a developmental level, have key activation of hypoxic pathways (a known regulator of malignant stem cell phenotypes) as well as activation of genes involved in apoptosis and proliferation.
The data show that planktonic bacteria seem to be regulated at a landscape scale controlled by land use, whereas biofilm bacteria are regulated at a biofilm matrix scale controlled by autochthonous production.
Most central metabolic pathways are regulated at a few key steps, typically through enzymes whose activity involves the hydrolysis of ATP.
Vehicle travel on the Foothill (210) Freeway was not included in the local emissions report, as freeways are regulated at a level beyond La Cañada's jurisdiction.
The cornerstones of ED are that (a) movement behaviors are examined and understood at the performer-environment scale of analysis; (b) perception of information provides opportunities for action (i.e., affordances) and is the basis of how behaviours are regulated at an individual level; and (3) performance behaviours are self-organized over time under interacting constraints [34, 52, 53].
There is also the possibility several indirectly regulated proteins may be regulated at a tertiary level involving secondary regulators that control expression of additional tertiary transcription factors that subsequently affect cyst development (Fig. 4).
For example, mRNA levels in Drosophila [68] were found to be regulated at a post-transcriptional level without evident transcriptional regulation; however, simultaneous inhibition of both Erk and p38 kinase pathways decreased the levels of cytokine gene transcription (IL-6 and TNF-α) [69].
Cre-EBD can also be regulated at a transcriptional level by cell-cycle specific or constitutive promoters.
They also contribute to the understanding of how the nucleotide salvage pathway is regulated at a molecular level.
