It has also been reported that miR-142-3p effectively inhibits autophagy in a NOD2-dependent manner and
downregulates IL-8 mRNA expression [30].
Thus, according to these data, the most beneficial miR to combine with IL-27 for reducing inflammatory activity of macrophages would be miR-21 and miR-29b (Figure 6(c), yellow arrowheads), as they
downregulate or stabilize IL-17a levels and
downregulate TNF and Stat3, while enhancing the effect of IL-27 on Stat1 activation.
These data collectively indicate that RR
downregulates UVB-induced oxidative stress more potently than NR or R alone and therefore reduces its contribution to skin aging.
The regulatory basis for this inability to sufficiently
downregulate iron absorption is unknown, but disruptions in the hepcidin-ferroportin axis are likely candidates based on recent research in humans and laboratory rodents.
verticillata extract used in our study was found to
downregulate p53.
And in some cases, high doses
downregulate responses triggered by lesser exposures--in other words, different effects can appear and disappear at different doses.
To achieve their goal, a team chose to "
downregulate"-- a process that involves decreasing a cellular component--the caffeic acid 3-O-methyltransferase, or COMT, gene in the Alamo variety of switchgrass.
MicroRNA 150 has been shown to
downregulate the expression of C-MYB, a transcription factor that plays a significant role in megakaryopoiesis.
The kidneys perceive the pressure in the vessel and up- or
downregulate the amounts of these hormones, which determines the "tone" of the vessel or the outside pressure.
Among several approaches to prevention of Type 1 diabetes (T1D), "vaccination" using islet autoantigens (intact or altered peptides derived from insulin, [GAD.sub.65] or other proteins) stands out as potentially inducing long-term tolerance by induction of regulatory T cells that
downregulate immunity to autoantigens.
But the mitogen-activated protein (MAP) kinase pathway, which mediates vasoconstriction, is driven by high levels of insulin and thus, does not
downregulate with insulin resistance.
