But regulations it plans to introduce at a later date to regulate emissions from existing plants would happen through a different section of the Clean Air Act, one enforced by the states.
Recently, a search for mitochondrial proteins that bind pioglitazone identified a novel protein, mitoNEET, which was later shown to regulate the oxidative capacity of the mitochondria.
HIF-1 was discovered in an investigation of the regulation of human erythropoietin gene, which encodes erythropoietin [ 56], and it was later shown to regulate VEGF expression [ 57].
The main difference was that the South African government contracted CSOs to provide CHBC services whereas in Malawi and Zambia the programmes had been set up independently of government PHC initiatives and governments later sought to regulate them; for example, by introducing common standards for training of caregivers and provision of care.
It was originally identified as a binding partner of the transcription factor Oct-4 in ES and embryonal carcinoma (EC) cells, where it is crucial for the expression of FGF-4 (13), and was later shown to regulate the expression of many other ES cell-specific genes.
PAR-1 (Ser/Thr kinase) appears dispensable for flows, but is required later to negatively regulate the activity and stability of MEX-5/MEX-6, and to restrict P granules and PIE-1 to the posterior [ 31].
The mightier of the later Carolingians attempted to regulate local magnates and enlist them in their service, but the power of local elites was never effaced.
From these data we conclude that FGF20 alone does not affect progenitor cell number, but rather functions later in development to regulate epithelial patterning (differentiation).
A challenging concept that needs further testing is whether the chromatin loops (captured at 45 minutes) are stable over time or whether they change, leading to the formation of new loops at later time points to regulate transcription of the 'late' target genes.
In mammals, Foxa1 binds and activates genes expressed in foregut endoderm derived lineages and is required for fetal development, but gene deletion in adulthood shows that Foxa1 function later in life is to regulate glucose homeostasis.
