Thus, in addition to mature OLs, the activity of the classic MBP promoter appeared to drive expression of golli J37 in OPCs, later-stage OL progenitors and immature OLs.
To assure that the 30 kDa band of p30 protein was representative for mature MLV, the activity of reverse transcriptase (RT) in the spleen homogenates was analyzed.
GPDH activity is high in mature adipocytes; the activity of this enzyme is therefore routinely measured to assess adipogenic differentiation in cultured cells [ 35] and has been used as an index for monitoring triglyceride synthesis [ 21].
In mature T cells, the activity of these DGK isoforms aids in the maintenance of self-tolerance by preventing T-cell hyperactivation upon T cell receptor stimulation and by promoting T-cell anergy.
HDL arises as nascent discoidal particles, which are remodeled to mature spherical HDL through the activity of lecithin cholesterol acyltransferase (LCAT; ref. 1).
However, in late differentiation, the kinase activity of mTOR becomes necessary for the formation of mature myotubes, by modulating the activity of 4E-BP1 and S6K1 [34].
We believe that such analyses can only establish correlations, but not causal relationships, between the levels of mature miRNA expression and the activity of miRNA genes.
As recently reviewed, the 5-HT neurons are involved in respiratory function and dysfunction [14], they synaptically contact the RRG [15], modulate the activity of the maturing RRG [16], are intrinsically chemosensitive in vitro, are stimulated by hypercapnia in vivo, and their disruption alters the ventilatory response to CO2/pH changes [12], [17], [18].
Previous studies demonstrated that reversible oxidation inhibited HIV-1 maturation through the inhibition of protease activity and that the activity of mature protease could be regulated by such oxidation of residues at the dimer interface, thus interfering with dimerization[7], [8], [23].
Their fate during differentiation and development and the activity of mature neurons are significantly determined and regulated by chromatin.
Thus we show that the levels of proBDNF decreased and the activity of mature BDNF increased in CA1 after fear conditioning.
